Texas Instruments ADS62P22IRGCR

Overview

ADS62P22IRGCR from Texas Instruments is a dual-channel, 12-bit analog-to-digital converter with 65 MSPS maximum sampling rate, DDR LVDS or parallel CMOS outputs, and integrated digital processing block (offset correction, fine gain in 0.05 dB steps, decimation by 2/4/8, and programmable 24-tap filters). It operates from –40°C to 85°C and targets high-fidelity signal acquisition in software-defined radio baseband receivers.

For engineers reviewing the ADS62P22IRGCR datasheet, ADS62P22IRGCR pinout, ADS62P22IRGCR application, or ADS62P22IRGCR equivalent, this page delivers verified specifications, package-validated pin functions, real-world use cases in wireless infrastructure, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The ADS62P22IRGCR implements a pipelined ADC architecture with internal sample-and-hold and low-jitter clock buffer, enabling 71.5 dBFS SINAD at 10 MHz input and 69.2 dBFS at 190 MHz with 3.5 dB coarse gain. Its digital processing block is configurable via parallel control pins (CTRL1–CTRL3, SEN, SCLK) or serial interface (SEN/SCLK/SDATA), supporting independent channel power-down, MUX mode, and external reference operation.

It supports multiple clock inputs (LVPECL, LVDS, LVCMOS, sine) down to 400 mV_PP, includes a clock duty cycle stabilizer, and provides dual output interfaces: DDR LVDS (with 225–350 mV differential swing) or parallel CMOS (1.8 V to 3.3 V DRVDD). The device uses an internal 1 V/2 V reference but accepts external reference via VCM pin (1.45–1.55 V).

FAQ

What is the maximum sampling rate supported by the ADS62P22IRGCR?

The ADS62P22IRGCR supports a maximum sampling rate of 65 MSPS, as specified in the SLAS576C datasheet. This rate is guaranteed across the full industrial temperature range (–40°C to 85°C) with AVDD = 3.3 V and proper clock conditioning. Exceeding this rate may cause missing codes or degraded SFDR performance. The ADS62P22IRGCR is the lowest-speed variant in the ADS62P2X family, optimized for power-constrained SDR and instrumentation applications.

Does the ADS62P22IRGCR include an internal voltage reference?

Yes, the ADS62P22IRGCR integrates an internal reference with VREFT = 2 V and VREFB = 1 V, yielding a 1 V reference span. It also supports external reference operation via the VCM pin, which must be biased between 1.45 V and 1.55 V. In internal reference mode, VCM outputs a stable 1.5 V common-mode voltage with ±0.1 V tolerance and 4 mA drive capability-eliminating external reference ICs and associated decoupling components.

Can the ADS62P22IRGCR operate with a 1.8 V digital supply (DRVDD)?

Yes, the ADS62P22IRGCR supports DRVDD from 1.65 V to 3.6 V for CMOS outputs and 3.0 V to 3.6 V for LVDS outputs. At 1.8 V DRVDD, CMOS output drive strength is reduced, and the device output clock (CLKOUT) must not be used for data capture-instead, a delayed version of the input clock is recommended. The datasheet specifies 18 mA typical digital supply current at 1.8 V DRVDD with 10 pF load, enabling low-voltage FPGA interfacing.

What digital processing functions are available in the ADS62P22IRGCR?

The ADS62P22IRGCR includes an on-chip digital processing block featuring offset correction, fine gain adjustment in 0.05 dB steps, decimation by factors of 2/4/8, and programmable 24-tap FIR filters (low-pass, high-pass, band-pass). These functions are configurable via parallel pins or serial interface registers. By default, the block is bypassed; enabling it reduces FPGA resource utilization and simplifies signal conditioning in SDR and test equipment designs.

Is the ADS62P22IRGCR pin-compatible with other devices in the ADS62P2X family?

Yes, the ADS62P22IRGCR is pin-compatible with ADS62P23IRGCR, ADS62P24IRGCR, and ADS62P25IRGCR-all share the same 64-pin QFN (RGC) package, identical pinout, and compatible power/ground layout. This allows drop-in replacement for speed upgrades (e.g., swapping ADS62P22IRGCR for ADS62P23IRGCR) without PCB redesign, provided thermal and power delivery margins accommodate the higher analog power (594 mW vs. 515 mW).
