GENERAL INFORMATION The CRD4614-5 is a reference design of a production-grade AC `97 PCI Audio card using the CrystalClear CS4614 SoundFusion PCI Audio Accelerator and the CS4297 SoundFusion Audio Codec `97. These two integrated circuits demonstrate Cirrus' powerful DSP controller and unsurpassed CrystalClear audio quality in a single PCI add-in card reference design. The CRD4614-5 audio measurements meet or exceed Microsoft's PC'97 and PC'98, both required and advanced, audio preformance requirements. Today's multimedia applications demand high quality PC audio and numerous audio connections. To meet this demand, Intel(R) defined the AC `97 (Audio Codec `97) specification that defines a two chip audio solution [1]. The advantage of a two chip audio solution is that the analog section of a system can be completely separated from the noisy digital environment of a personal computer. A 5-wire digital link is all that is required to connect the audio codec to the PCI bus-based AC'97 controller. This allows the audio section to reach the required signal to noise ratio of ~90 dB while making the layout and placement of the audio section easier to implement. In the Windows 95 environment, a MIDI stream and a number of simultaneous audio streams from Windows 95 applications can be sent to the CS4614 over the PCI bus. The CS4614 performs hardware accelerated audio stream mixing and processing, including sample rate conversion, 3D positional audio processing and wavetable synthesis, then sends the output stream over the AC `97 Link to the CS4297. The CS4297 performs the Digitalto-Analog Conversion (DAC) for this digital audio output stream and also provides multiple analog audio inputs and outputs, analog mixing and Analog-to-Digital Conversion (ADC). In the native DOS environment, the CS4614 provides legacy games compatibility in hardware. DOS applications may directly address the legacy register set for SoundBlaster Pro compatibility, an integrated FM synthesizer, as well as the gameport. The CS4614 also provides an MPU-401 interface in native DOS. In this environment the CS4614 receives the MIDI data through legacy compatible I/O. The CS4614 performs the wavetable synthesis function and sends the synthesized audio stream to the CS4297 via the AC Link for digital to analog conversion. This card is designed to provide the highest possible functionality, along with industry leading audio performance at a low manufacturing cost. Care was taken with component placement and signal routing to minimize sources which can degrade audio performance. Cirrus' analog design know-how has resulted in a board which preserves the exceptional analog performance of the CS4614 and CS4297. CIRRUS LOGIC ADVANCED PRODUCT DATABOOK 2 DS292RD1E1 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter REFERENCE DESIGN FEATURES The CRD4614-5 reference design illustrates a low cost two-layer, single sided add-in card layout. The card is sectioned into three main parts: the CS4614 PCI Audio Accelerator section, the CS4297 Audio Codec `97 section, and the Analog I/O section. also take MIDI data from an external source to the CS4614. A buffer circuit allows the MIDIOUT pin of the CS4614 to drive an external MIDI input. External EEPROM The CS4614 EEPROM contains the required Subsystem Vendor ID and Subsystem ID values as well as two configuration registers which configure the software driver of the CS4614 to operate in AC `97 link mode. The CS4614 currently requires 7 data bytes in the EEPROM for configuration. The PCI Special Interest Group assigns manufacturers a Subsystem Vendor ID. To meet WHQLTM standards, the Subsystem ID must be a non-zero value. A utility, PCIRSRC.EXE, is supplied in this kit to download configuration and OEM specific data to the EEPROM. Please call Cirrus Logic PC Products Audio Division at (512) 445-7222 to have a Subsystem ID assigned to a particular project. For information regarding the programming and timing of the EEPROM, refer to the CS4614 Data Sheet [3]. CS4614 PCI Audio Accelerator Section The CS4614, a PCI 2.1 compliant device, is a bus mastering, 255 MIPS DSP optimized for audio signal processing. An efficient on-chip DMA controller and stream processor DSP core provide a number of signal processing functions including: * Hardware acceleration for Windows 95 DirectSound(R), DirectSound3D(R), DirectShowTM and Aureal A3D API's 3-D positional processing for DirectSound3D API calls using HRTF-based 3D algorithms Mixing and sample rate conversion for multiple concurrent 2D and 3D digital audio streams Concurrent General MIDI compliant, wave- table synthesis with 64-note polyphony and chorus/reverb effects processing * * * Power Requirements The area around the CS4614 includes the required bypass capacitors, PLL power supply filter components, an EEPROM, the components for the joystick connection and a buffer circuit for the external MIDI connection. The layout of this section complies with the PCI specification version 2.1 [2] for add-in cards. Please refer to the schematic and layout sections of this document for more information. For more information on the CS4614, refer to the CS4614 Data Sheet [3]. 3.3 V power for the CS4614 is generated from the +5 V on the PCI connector and regulated to +3.3 V using a low dropout linear voltage regulator. This is required since all PCI slots are not guaranteed to have +3.3 V power pins available in the PCI connector slot. The maximum current requirement for the +3.3 V power supply is 225 mA with a typical operating current in the 150-200 mA range during normal audio processing tasks. CS4297 Audio Codec `97 Section This section contains the components for the Mic In, Line In, and Line Out audio connections. It also includes a 24.576 MHz crystal that acts as the master clock in an AC `97 configuration. The capacitors required for the CS4297 and their placement are discussed in the CS4297 Data Sheet[4]. Refer 3 Joystick/MIDI connection The DB-15 connector allows a joystick or an external MIDI device to be connected to the CS4614. In the AC' 97 configuration, the CS4614 handles the joystick operation. The external connection can CIRRUS LOGIC ADVANCED PRODUCT DATABOOK DS292RD1E1 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter to the Grounding and Layout section of the data sheet for the recommended routing the audio section. Three external 1/8" jacks and four internal header connections are used for analog inputs and outputs. Line Out The output of the CS4297 is capable of driving impedances greater than 10 k with a maximum output voltage of 1 Vrms. These loads are generally self powered speakers. Two additional population options are available. The first option is a lownoise, low distortion amplifier for driving headphones, typically impedancies greater than 32 . The second option is a power amplifier for driving 8 or 4 speakers. The Line Out connection is through the external 1/8" jack. * Maximum output level: 1 Vrms Power Requirements A Motorola MC78L05CDT regulates the PCI +12 V supply down to provide a clean +5 V analog supply for the CS4297. A power regulator is recommended for the analog voltage supply to provide good audio signal quality. The MC78L05CDT regulator can provide up to 100 mA of current, which is enough power for the CS4297 and associated analog circuitry. Analog I/O Section The CS4297 has many analog inputs and outputs that may or may not be used depending on the system's application. Unused inputs should be tied to Vrefout (pin 28) or capacitively coupled to the analog ground plane. The analog section contains the components for a headphone amplifier or power amplifier as a stuff option. The Modem Audio, CD ROM, Video In and Aux In headers are also part of the Analog I/O section. Each header has a few resistors and capacitors associated with it. The header and its associated components may or may not be necessary depending on the audio inputs implemented. Headphone Amp output option: * * Capable of driving low impedance loads such as 32 headphones Maximum output level: 2.0 Vrms Power Amp output option: * * Capable of driving low impedance loads such as 4 or 8 speakers Maximum output level: 2.9 Vrms into 4 or 8 Mic In The Microphone In 1/8" jack provides a singleended microphone input (as opposed to differential), supporting most common types of dynamic or phantom powered microphones. The microphone input provides no signal amplification, but a 20 dB gain block inside the CS4297 can be software enabled (the "Boost" button in the Windows input applet) if signal levels are too low. In many cases, the additional "Boost" will be required with the CRD4614-5 implementation in order to achieve a desirable audio level. * Supports 3-pin phantom power and dynamic microphones Audio Inputs and Outputs A full feature set of the CS4297's analog I/O is represented on the reference design card through internal headers and external connectors: * * * * * * * Line Out Mic In Line In CD ROM In Modem audio connection Aux In Video In CIRRUS LOGIC ADVANCED PRODUCT DATABOOK 4 DS292RD1E1 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter * Microphone power is provided on the ring connection of the 1/8" stereo jack * Wired as: * * Pin 1 : Phone_In (from modem) Pin 2 : Analog Ground Pin 3 : Analog Ground Pin 4 : Mono_Out (to modem) Line In The Line In 1/8" jack provides an input to the Line In pins of the CS4297. * Maximum input level: 1 Vrms Phone_In maximum input level : 1 Vrms Mono_Out maximum output level: 0.7 Vrms CD ROM In The CD-ROM audio input headers are connected in parallel, which means only one can be active at a time. The first header is a 4 pin (0.1 inch center) shrouded connector that fits most CD ROM audio adapter cables. The second is a 4 pin ( 2 mm center) shrouded connector. The OEM will need to make it clear to end users which one to use, or delete the unused connector entirely. * * * Maximum input level: 1 Vrms Differential input using the CD common pin as the ground 0.1 inch connector wired as: * Pin 1 : Left Channel Pin 2 : Analog Ground Pin 3 : Analog Ground Pin 4 : Right Channel Pin 1 : Right Channel Pin 2 : Analog Ground Pin 3 : Left Channel Pin 4 : Analog Ground Aux In * * Internal 4 pin header (0.1 inch center) Wired as: * Pin 1 : Left Channel Pin 2 : Analog Ground Pin 3 : Analog Ground Pin 4 : Right Channel Maximum input level: 1 Vrms Video In * Internal 4 pin header (0.1 inch center) * Wired as: Pin 1 : Left Channel Pin 2 : Analog Ground Pin 3 : Analog Ground Pin 4 : Right Channel 2 mm connector wired as: Maximum input level: 1 Vrms SCHEMATIC DESCRIPTION Figures 1 through 8 show the schematics for the CRD4614-5 card. This section will describe particular pages of the schematic that need to be discussed. Modem Audio Connection The Modem audio header provides an audio interface between the sound card and a modem. The Mono Out signal from the CRD4614-5 transfers audio to the Modem, and Phone In receives audio from the modem. * Internal 4 pin header (0.1 inch center) Figure 2 : CS4614 PCI Accelerator The 0.1 F capacitors connected to the power pins of the CS4614 should be as close as possible to the chip. L3, C56, and C57 are used to filter the power supply for the internal PLL circuit. R19 and R20 CIRRUS LOGIC ADVANCED PRODUCT DATABOOK DS292RD1E1 5 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter are termination resistors in the serial AC link between the CS4297 and the CS4614. The low drop out voltage regulator, the Micrel MIC2920A, is used to provide the required +3.3 V to the CS4614 in the absence of +3.3V on the PCI bus. Two packaging options are supported. U8 is a SOT-223 surface mount package, and U9 is a TO-220 pin-inhole package. Zero ohm resistors are provided as a stuffing option if +3.3V is known to be available on the PCI bus. populating R3 is not compliant with PC-99 Audio Specifications. An additional CD-ROM connector footprint, J2, is provided to support the legacy 2mm, Panasonic style, analog connector. Since J1 and J2 are in parrallel, only one CD-ROM audio cable can be installed. It is recommended that only one connector be installed at build time. If both are populated for maximum flexability, care should be taken by the OEM to notify users that only one device can be attached. Figure 3 : CS4297 AC'97 Audio Codec For the best audio performance, the analog voltage regulator, an MC78L05, should be located near the CS4297. Two packaging options are supported. U2 is an SO8 surface mount package, and U3 is a TO92 pin-in-hole package. R17 and R18 are termination resistors in the serial AC link between the CS4297 and the CS4614. NPO-type capacitors should be used on all loading capacitors of audio signals to ensure minimal added distortion. Two footprints are also provided for the crystal, XTAL. A CA-301 pin-in-hole footprint, Y1, for miniature crystals, and a standard HC-49U package, Y2, which can be bent over and soldered to the card. Figure 5 : Aux In, Video In, Modem The 220 pF capacitors on these input lines are provided for EMC suppression. These may be removed if EMC testing determines they are not required. No standard exists for the internal modem connector. R34, R35, and R36 are added in case voltage dividers are required to adjust signal levels. Figure 6 : Line Out, Headphone Amp, Power Amp Three population options are provided for audio out. The first population option is a headphone amplifier, the Motorola MC1458, which is capable of driving stereo headphones with impedances greater than 32 or powered speakers. A jumper must be installed across pins 2 & 3 of J7 and J9 for proper operation. The headphone amp can be bypassed by the OEM or customer by installing the jumper across pins 1 & 2 of J7 and J9. The second population option is the addition of a power amplifier, the Philips TDA1517P. This op amp is capable of driving 4 or 8 speakers as well as headphones and powered speakers with a marginal decrease in audio performance. A jumper must be installed across pins 2 & 3 of J7 and J9 for proper operation. The power amp can be bypassed by the OEM or customer by installing a jumper across pins 1 & 2 of J7 and J9. Figure 4 : Line In, Mic In, CD-ROM In The 220 pF capacitors on these input lines are provided for EMC suppression. These may be removed if EMC testing determines they are not required. 1 F capacitors are used on the Line In circuit to decrease the low-end frequency corner. Notice the absence of a voltage divider on these inputs. The maximum signal level that can be apply to these inputs is 1 Vrms. Phantom power, derived from the clean +5VA, is applied to the "ring" of the Mic In jack. A 10 F capacitor is added for additional filtering. If a microphone that requires phantom power on "tip" is shipped with this product by the OEM, then R3 should be populated and R2 removed. Note that CIRRUS LOGIC ADVANCED PRODUCT DATABOOK 6 DS292RD1E1 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter The third and least expensive option is to not populate either the headphone amp or power amp. This option is the least flexible since only powered speakers can be driven. A jumper must be installed across pins 1 & 2 of J7 and J9 for proper operation. * * * 8 pin devices will be in surface mount packages. the TDA1517P power amp will be pin in hole package dual footprint for XTAL. Standard H49U with GND pad and small circular CA-301 pin in hole package Dual footprint for +5 V and +3.3 V regulators. Surface mount and pin in hole packages are supported. Figure 7 : MIDI and Joystick Connection A buffer driver circuit is used on the MIDIOUT pin to provide necessary 5V TTL compatible output on the DB-15 connector. This circuit can be removed, and R37 populated to bypass the buffer circuit if a 3.3V compatible output is sufficient. Pull-up resistors are required for the joystick buttons and the MIDI input. L4, C72, C77, C78, C79 are provided for EMC suppression and can be removed if EMC testing shows they are not required. Replace L4 with a 0 ohm resistor. C73 - C76 and C80 - C83 are functional to the joystick circuitry as well as provide for EMC suppression and therefore must not be removed. * EMC Components A number of capacitors and inductors are included to help the board meet EMC compliance tests, such as FCC Part 15. These components are outlined in the schematic. They may or may not be needed in a particular design, so the footprints are added in case they are necessary. EMC testing should show where problem areas exist, and components can be added to those areas. EMC components can also be removed in areas that do not show problems. Figure 8 : PCI Bus Connection The PCI 2.1 specification requires that each unused +3.3 V power pin should be connected with an average of 0.01 F capacitor [2]. Seven 0.1 F capacitors in parallel provide the required capacitance for the +3.3 V power pins. Zero ohm resistors R43 and R44 can be used to omit the +3.3V regulator if this voltage is known to be provided on the PCI bus. GROUNDING AND LAYOUT The component layout and signal routing of the CRD4614-5 provides a good example of how to layout a PCI add-in card. PCI-bus based add-in cards have explicit requirements on trace lengths that are not imposed on motherboard designs. These trace length limits for add-in cards are as follows: * * * * Maximum trace length for 32-bit signals on 32bit and 64-bit cards is 1.5 inches. Maximum trace lengths for signals on the 64bit extension are 2 inches. Trace length for the PCI CLK signal is 2.5 inches 0.1 inch. The PCI CLK signal must drive only one load. Component Selection Great attention was given to the particular components used on the CRD4614-5 board with costs, performance, and package selection as the most important factors. Listed are some of the guidelines used in the selection of components: * * * all capacitors greater than 1 F will be pin in hole aluminum type. no components smaller than 0805 package use single package components - no resistor pacs Please refer to the PCI 2.1 Specification[2], Section 4.3.6, for information on routing PCI bus signals on a motherboard. CIRRUS LOGIC ADVANCED PRODUCT DATABOOK DS292RD1E1 7 CRD4614-5 CrystalClearTM AC '97 Low Cost PCI Audio Adapter Partitioned Voltage and Ground Planes The CRD4614-5 is partitioned into a digital and analog section to keep digital and analog ground currents from crossing. Ground currents from digital signals are inherently noisy with respect to analog signals and should be isolated from the audio section. The first rule in laying out mixed signal PCBs is to keep all digital signals over the digital ground plane and all analog signals over the analog ground plane. When digital and analog signals cross planes, they introduce noise into the audio section reducing performance. The pinout of the CS4297 allows the ground split to completely separate digital signals on one side and analog signals on the other. This split is located very close to the CS4297 so analog and digital ground return currents originating from the CS4297 may flow through their respective ground planes. A bridge is made across the split to maintain the proper reference potential for each ground plane. The area around the crystal oscillator and the two XTAL signals should be filled with copper on the top and bottom sides and attached to digital ground. This ground plane serves to keep noise from coupling onto these pins. All data converters are highly susceptible to noise on the crystal pins. A separate chassis ground is also used for EMC purposes. All of the components that are for EMC compliance are referenced to this plane. The chassis ground plane is connected to the analog ground plane at the external jacks. Chassis ground is also connected to digital ground near the joystick connector. CS4297 Layout Notes Refer to the CS4297 Data Sheet[4] on how the area under the chip should be partitioned and how the bypass capacitors should be placed. Pay close attention to the suggestions for the bypass capacitors on REFFLT, AFLT1, AFLT2 and the power supply capacitors. The pinout of the CS4297 is designed to keep digital and analog signals from crossing when laying out the board.
