ADC1213S series
Single 12-bit ADC; 65 Msps, 80 Msps, 105 Msps or 125 Msps; serial JESD204A interface
Rev. 1 -- 14 March 2011 Product data sheet
1. General description
The ADC1213S is a single channel 12-bit Analog-to-Digital Converter (ADC) optimized for high dynamic performance and low power at sample rates up to 125 Msps. Pipelined architecture and output error correction ensure the ADC1213S 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 outputs data in serial mode via a single differential lane, which complies with the JESD204A standard. The integration of Serial Peripheral Interface (SPI) allows the user to easily configure the ADCs and the serial output modes. The device also includes a programmable full-scale SPI to allow a flexible input voltage range from 1 V (p-p) to 2 V (p-p). Excellent dynamic performance is maintained from the baseband to input frequencies of 170 MHz or more, making the ADC1213S ideal for use in communications, imaging, and medical applications.

11. Application information
11.1 Analog inputs
11.1.1 Input stage description
The analog input of the ADC1213S supports a differential or a single-ended input drive. Optimal performance is achieved using differential inputs with the common-mode input voltage (VI(cm)) on pins INP and INM 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 11.2 and Table 21). 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.
11.1.2 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.

11.2 System reference and power management
11.2.1 Internal/external reference
The ADC1213S has a stable and accurate built-in internal reference voltage to adjust the ADC full-scale. This reference voltage can be set internally via SPI or with pins VREF and SENSE (see Figure 11 to Figure 14), in 1 dB steps between 0 dB and -6 dB, via SPI control bits INTREF[2:0] (when bit INTREF_EN = logic 1; see Table 21). The equivalent reference circuit is shown in Figure 10. An external reference is also possible by providing a voltage on pin VREF as described in Figure 14.

11.2.3 Common-mode output voltage (VO(cm))
An 0.1 F filter capacitor should be connected between pin VCM and ground to ensure a low-noise common-mode output voltage. When AC-coupled, this pin can be used to set the common-mode reference for the analog inputs, for instance via a transformer middle point.

Single-ended or differential clock inputs can be selected via the SPI (see Table 20). If single-ended is selected, the input pin (CLKM or CLKP) is selected via control bit SE_SEL. If single-ended is implemented without setting bit SE_SEL accordingly, the unused pin should be connected to ground via a capacitor.
11.3.3 Duty cycle stabilizer
The duty cycle stabilizer can improve the overall performance of the ADC by compensating the input clock signal duty cycle. When the duty cycle stabilizer is active (bit DCS_EN = logic 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 = logic 0), the input clock signal should have a duty cycle of between 45 % and 55 %.

11.3.4 Clock input divider
The ADC1213S contains an input clock divider that divides the incoming clock by a factor of 2 (when bit CLKDIV2_SEL = logic 1; see Table 20). 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.

11.5.1 Digital JESD204A formatter
The block placed after the ADC core is used to implement all functions of the JESD204A standard. This ensures signal integrity and guarantees the clock and the data recovery at the receiver side. The block is highly parameterized and can be configured in various ways depending on the sampling frequency and the number of lanes used.

11.6 Serial Peripheral Interface (SPI)
11.6.1 Register description
The ADC1213S serial interface is a synchronous serial communications port allowing for easy interfacing with many industry microprocessors. 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). Pin SCLK acts as the serial clock and pin CS acts as the serial chip select. Each read/write operation is sequenced by the CS signal and enabled by a LOW level to to drive the chip with N 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 (logic 1) or write (logic 0) transfer occurs after the instruction byte.
Table 15. R/W[1] 0 1
[1]
Read or Write mode access description Description Write mode operation Read mode operation
Bits W1 and W0 indicate the number of bytes transferred.
Table 16. W1 0 0 1 1
Number of bytes to be transferred W0 0 1 0 1 Number of bytes transferred 1 byte 2 bytes 3 bytes 4 or more bytes
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 pin CS in combination with a rising edge on pin 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 is always a multiple of 8 bits. The MSB is always sent first (for instruction and data bytes). 4. A rising edge on pin CS indicates the end of data transmission.

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.
