ADC1213D series Dual 12-bit ADC; 65 Msps, 80 Msps, 105 Msps or 125 Msps Rev. 05 -- 23 April 2010 Preliminary data sheet 1. General description The ADC1213D is a dual-channel 12-bit Analog-to-Digital Converter (ADC) optimized for high dynamic performances and low power at sample rates up to 125 Msps. Pipelined architecture and output error correction ensure the ADC1213D is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a 3 V source for analog and a 1.8 V source for the output driver, it embeds two serial outputs. Each lane is differential and complies with the JESD204A standard. An integrated Serial Peripheral Interface (SPI) allows the user to easily configure the ADC. A set of IC configurations is also available via the binary level control pins taken, which are used at power-up. The device also includes a SPI programmable full-scale to allow flexible input voltage range from 1 V to 2 V (peak-to-peak). Excellent dynamic performance is maintained from the baseband to input frequencies of 170 MHz or more, making the ADC1213D ideal for use in communications, imaging, and medical applications. 2. Features and benefits SNR, 70 dBFS; SFDR, 86 dBc Sample rate up to 125 Msps Clock input divider by 2 for less jitter contribution 3 V, 1.8 V single supplies Flexible input voltage range: 1 V to 2 V (peak-to-peak) Two configurable serial outputs INL 1 LSB; DNL 0.5 LSB Pin compatible with the ADC1213D series HVQFN56 package Input bandwidth, 600 MHz Power dissipation, 995 mW at 80 Msps SPI register programming Duty cycle stabilizer High IF capability Offset binary, two's complement, gray code Power-down mode and Sleep mode Compliant with JESD204A serial transmission standard 3.

SPI timings 14. Application information 14.1 Analog inputs 14.1.1 Input stage description The analog input of the ADC1213D supports differential or single-ended input drive. Optimal performance is achieved using differential inputs with the common-mode input voltage (VI(cm)) on pins INxP and INxM set to 0.5VDDA. The full scale analog input voltage range is configurable between 1 V (p-p) and 2 V (p-p) via a programmable internal reference (see Section 14.2 and Table 21 for further details). Figure 6 shows the equivalent circuit of the sample and hold input stage, including ElectroStatic Discharge (ESD) protection and circuit and package parasitics.

Input sampling circuit The sample phase occurs when the internal clock (derived from the clock signal on pin CLKP/CLKM) is HIGH. The voltage is then held on the sampling capacitors. When the clock signal goes LOW, the stage enters the hold phase and the voltage information is transmitted to the ADC core. 14.1.2 Anti-kickback circuitry Anti-kickback circuitry (RC filter in Figure 7) is needed to counteract the effects of a charge injection generated by the sampling capacitance. The RC filter is also used to filter noise from the signal before it reaches the sampling stage. The value of the capacitor should be chosen to maximize noise attenuation without degrading the settling time excessively. R INP C R INM 005aaa073 Fig 7. Anti-kickback circuit The component values are determined by the input frequency and should be selected so as not to affect the input bandwidth.

This reference voltage can be set internally via SPI or with pin VREF an SENSE (see Figure 11, Figure 12, Figure 13 and Figure 14), in 1 dB steps between 0 dB and -6 dB, via SPI control bits INTREF[2:0] (when bit INTREF_EN = 1; see Table 21). The equivalent reference circuit is shown in Figure 10. External reference is also possible by providing a voltage on pin VREF as described in Figure 13.

This feature allows the user to deliver a higher clock frequency with better jitter performance, leading to a better SNR result once acquisition has been performed. 14.3.4 Duty cycle stabilizer The duty cycle stabilizer can improve the overall performances of the ADC by compensating the input clock signal duty cycle. When the duty cycle stabilizer is active (bit DCS_EN = 1; see Table 20), the circuit can handle signals with duty cycles of between 30 % and 70 % (typical). When the duty cycle stabilizer is disabled (DCS_EN = 0), the input clock signal should have a duty cycle of between 45 % and 55 %.

It provides access to the registers that control the operation of the chip in both read and write modes. This interface is configured as a 3-wire type (SDIO as bidirectional pin). SCLK acts as the serial clock, and CS acts as the serial chip select bar. Each read/write operation is sequenced by the CS signal and enabled by a LOW level to to drive the chip with 2 bytes to 5 bytes, depending on the content of the instruction byte (see Table 14). Table 14. Bit Description Instruction bytes for the SPI MSB 7 R/W[1] A7 [1] LSB 6 W1 A6 5 W0 A5 4 A12 A4 3 A11 A3 2 A10 A2 1 A9 A1 0 A8 A0 R/W indicates whether a read or write transfer occurs after the instruction byte Table 15.

Preliminary data sheet Rev. 05 -- 23 April 2010 23 of 41 NXP Semiconductors ADC1213D series ADC1213D series Bits A12 to A0 indicate the address of the register being accessed. In the case of a multiple byte transfer, this address is the first register to be accessed. An address counter is incremented to access subsequent addresses. The steps involved in a data transfer are as follows: 1. The falling edge on CS in combination with a rising edge on SCLK determine the start of communications. 2. The first phase is the transfer of the 2-byte instruction. 3. The second phase is the transfer of the data which can be vary in length but will always be a multiple of 8 bits. The MSB is always sent first (for instruction and data bytes): CSB SCLK SDIO R/W W1 W0 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 D7 D6 D5 D4 D3 D2 D1 D0 D7 D6 D5 D4 D3 D2 D1 D0 Instruction bytes Register N (data) Register N + 1 (data) 005aaa086 Fig 23. Transfer diagram for two data bytes (3-wire type) 14.6.2 Channel control The two ADC channels can be configured at the same time or separately. By using the register "Channel index", the user can choose which ADC channel will receive the next SPI-instruction. By default the channel A and B will receive the same instructions in write mode. In read mode only A is active. ADC1213D_SER_5 All information provided in this document is subject to legal disclaimers. (c) NXP B.V. 2010. All rights reserved.

Please consult the most recently issued document before initiating or completing a design. The term `short data sheet' is explained in section "Definitions". The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status information is available on the Internet at URL http://www.nxp.com. 17.2 Definitions Draft -- The document is a draft version only. The content is still under internal review and subject to formal approval, which may result in modifications or additions. NXP Semiconductors does not give any representations or warranties as to the accuracy or completeness of information included herein and shall have no liability for the consequences of use of such information. Short data sheet -- A short data sheet is an extract from a full data sheet with the same product type number(s) and title. A short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information. For detailed and full information see the relevant full data sheet, which is available on request via the local NXP Semiconductors sales office. In case of any inconsistency or conflict with the short data sheet, the full data sheet shall prevail. Product specification -- The information and data provided in a Product data sheet shall define the specification of the product as agreed between NXP Semiconductors and its customer, unless NXP Semiconductors and customer have explicitly agreed otherwise in writing. In no event however, shall an agreement be valid in which the NXP Semiconductors product is deemed to offer functions and qualities beyond those described in the Product data sheet. malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage. NXP Semiconductors accepts no liability for inclusion and/or use of NXP Semiconductors products in such equipment or applications and therefore such inclusion and/or use is at the customer's own risk.
