PRODUCT SUMMARY
CX20524 Mixed Signal Device for GSM and GPRS Applications
Applications
* GSM handsets and modules (850/900/1800/1900 MHz) * GPRS handsets and modules (850/900/1800/1900 MHz)
Description
The CX20524 Mixed Signal Device (MSD) is a highly integrated device designed for use in multi-band Global System for Mobile communications (GSM) and General Packet Radio Service (GPRS) handsets. The MSD includes all the power management, voice-band, mixed signal, and radio control functions required in a GSM/GPRS handset and module.
Features
* Supports multi-slot GPRS up to Class 12 * Analog-to-Digital Converters (ADCs) for digitization of In the receive path, the MSD digitizes the baseband Inbaseband receive signal Phase/Quadrature (I/Q) inputs. Digital samples are then sent to * Receive path PGA for AGC of received signal the Baseband Processor (BP) via the Rx serial interface. The * GMSK Digital Modulator receive path features a programmable gain amplifier (PGA) for * Digital-to-Analog Converters (DACs) for analog conversion of Automatic Gain Control (AGC) of the receive signal. the GMSK modulator output * Transmit power ramping and power level control In the transmit path, bursts of digital data are input to the MSD * Low noise voiceband ADC for direct interface to handset and over the control port. A Gaussian Minimum-Shift Keying headset microphone (GMSK) modulator generates modulated I and Q waveforms * Low noise voiceband DAC for direct interface to handset and from the input data. The I and Q waveforms are converted into headset speaker analog waveforms and output from the MSD. * Auxiliary 8-bit ADC for monitoring system signals The CX20524 generates an analog signal to control the .com * 3 V/1.8 V SIM card interface handset Power Amplifier (PA) output level. * Temperature sensor The device voiceband Codec section provides an interface to a * High speed asynchronous serial ports for interface to 32 handset speaker and microphone. Line In/Out signals are Skyworks Baseband Processor device also available to interface with audio accessories, such as a * Low speed asynchronous serial port for power management headset or car kit. functions * Voltage regulators for both internal (fixed voltage) and The MSD is designed to operate directly from a single cell, system (programmable voltage) needs 3.6 V Li Ion battery with no external regulation required. The * Low power operation MSD integrates all necessary Low Drop Out (LDO) voltage * Control circuit for multi-chemistry advanced battery charger regulators that generate the required device and system power * Power-On Reset (POR) generation supplies from battery input. * Over current-limiting An integrated SIM interface circuit allows direct interface to 3.0 * Power On/Off control inputs V and 1.8 V SIM cards with no external components. * CX20524-12: 160-pin FPBGA 12 mm x 12 mm package An integrated battery charger control circuit provides charging * CX20524-13: 180-pin FPBGA 10 mm x 10 mm package capabilities for multi-chemistry batteries. The CX20524-12 is packaged in a compact, 160-pin (12 mm x 12 mm) Fine Pitch Ball Grid Array (FPBGA), shown in Figure 2. The CX20524-13 is packaged in a compact, 180 pin 10 mm x 10 mm, 0.5 mm pitch, Fine Pitch Ball Grid Array (FPBGA), shown in Figure 3.
