ADC1613D series Dual 16-bit ADC; 65 Msps, 80 Msps, 105 Msps or 125 Msps; serial JESD204A interface Rev. 02 — 23 April 2010 Preliminary data sheet 1. General description The ADC1613D is a dual-channel 16-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 ADC1613D is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a 3.3 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 ADC1613D ideal for use in communications, imaging, and medical applications. 2.

Application information 13.1 Analog inputs 13.1.1 Input stage description The analog input of the ADC1613D supports differential or 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 13.2 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. Package ESD Parasitics Switch INAP INBP Ron = 15 Ω 1, 14 4 pF Cs Internal clock Switch INAM INBM Ron = 15 Ω 2, 13 4 pF Cs Internal clock 005aaa069 Fig 6. 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. 13.1.2 Anti-kickback circuitry Anti-kickback circuitry (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.

Dual transformer configuration The configuration shown in Figure 9 is recommended for high frequency applications. In both cases, the choice of transformer will be a compromise between cost and performance. 13.2 System reference and power management 13.2.1 Internal/external reference The ADC1613D 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 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.

When AC-coupled, these pins can be used to set the common-mode reference for the analog inputs, for instance via a transformer middle point.

The common-mode input voltage, VI(cm), at the inputs to the sample and hold stage (pins INAM, INBM, INAP, and INBP) must be between 0.9 V and 2 V for optimal performance. 13.3 Clock input 13.3.1 Drive modes The ADC1613D can be driven differentially (SINE, LVPECL or LVDS) with little or no influence on dynamic performances. It can also be driven by a single-ended LVCMOS signal connected to pin CLKP (CLKM should be connected to ground via a capacitor).

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. 13.3.4 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 %. Table 12.

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. Instruction bytes for the SPI MSB LSB Bit 7 6 5 4 3 2 1 0 Description R/W[1] W1 W0 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 [1] R/W indicates whether a read or write transfer occurs after the instruction byte Table 15. Read or Write mode access description R/W[1] Description 0 Write mode operation 1 Read mode operation [1] Bits W1 and W0 indicate the number of bytes transferred after the instruction byte. Table 16. Number of bytes to be transferred W1 W0 Number of bytes 0 0 1 byte transferred 0 1 2 bytes transferred 1 0 3 bytes transferred 1 1 4 or more bytes transferred 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.

All rights reserved. 25 of 43 ADC1613D series NXP Semiconductors ADC1613D series; serial JESD204A interface 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 Instruction bytes D7 D6 D5 D4 D3 D2 Register N (data) D1 D0 D7 D6 D5 D4 D3 D2 D1 D0 Register N + 1 (data) 005aaa086 Fig 23. Transfer diagram for two data bytes (3-wire type) 13.6.2 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. ADC1613D_SER_2 Preliminary data sheet All information provided in this document is subject to legal disclaimers. Rev. 02 — 23 April 2010 © NXP B.V. 2010.
