Texas Instruments ADS62C17IRGCR

Overview

ADS62C17IRGCR from Texas Instruments is a dual-channel, 11-bit, 200 MSPS analog-to-digital converter featuring TI's proprietary SNRBoost technology, DC offset correction, and programmable gain up to +6 dB in 0.5 dB steps. It delivers 79.8 dBFS SNR at 125 MHz IF with 20 MHz bandwidth and supports both DDR LVDS and parallel CMOS digital outputs for high-density communications baseband processing.

For engineers reviewing the ADS62C17IRGCR datasheet, ADS62C17IRGCR pinout, ADS62C17IRGCR application, or ADS62C17IRGCR equivalent, key selection considerations include its 200 MSPS sample rate, 90 dB cross-talk, 64-QFN (9 mm × 9 mm) package, internal/external reference flexibility, and SNRBoost-enabled bandwidth-specific SNR enhancement - all critical for multi-carrier wireless infrastructure and wideband receiver design.

Technical Context

The ADS62C17IRGCR integrates two independent 11-bit ADC cores with sample-and-hold, digital processing blocks per channel, and a shared clock generator. Its SNRBoost architecture applies programmable digital filtering to improve SNR within sub-Nyquist bandwidths (e.g., +6.0 dB SNR gain at 20 MHz BW), while maintaining full 200 MSPS throughput.

Dual output interfaces are supported: DDR LVDS (with 100 Ω differential termination, VOCM = 1.0–1.4 V) and parallel CMOS (DRVDD = 1.7–1.9 V), each with configurable data format (offset binary or 2's complement) and channel multiplexing capability. Internal reference eliminates external decoupling capacitors, though external reference mode remains fully supported via VCM pin.

Key Specifications

Pinout & Package

ADS62C17IRGCR is housed in a thermally enhanced 64-pin QFN package (RGC designation), 9 mm × 9 mm, with exposed thermal pad. Pin functions align with TI's standard dual-ADC layout: analog inputs (INA_P/M, INB_P/M), differential clock inputs (CLKP/CLKM), reference control (VCM), digital interface pins (DA0P/M–DA10P/M, DB0P/M–DB10P/M), and serial/parallel configuration pins (SEN, SCLK, CTRL1–3, SDATA).

FAQ

What is the maximum analog input frequency supported by the ADS62C17IRGCR?

The ADS62C17IRGCR supports a maximum analog input frequency of 500 MHz with a 2 V_PP differential input amplitude, and up to 800 MHz with a 1 V_PP amplitude - verified under recommended operating conditions (AVDD = 3.3 V, DRVDD = 1.8 V). This 700 MHz analog input bandwidth enables direct RF sampling in many broadband applications without external anti-alias filtering.

Does the ADS62C17IRGCR require an external reference voltage?

No, the ADS62C17IRGCR includes an internal reference and operates fully functional without external reference components. However, it also supports external reference mode via the VCM pin, allowing users to drive a precision external reference for improved absolute accuracy or system-level reference sharing - all without modifying the PCB layout.

How does SNRBoost technology improve performance in the ADS62C17IRGCR?

SNRBoost in the ADS62C17IRGCR applies programmable digital noise shaping to enhance SNR within user-defined bandwidths below Nyquist (e.g., +6.0 dB at 20 MHz BW). It does not alter sample rate or resolution; instead, it redistributes quantization noise energy out of the band of interest - delivering higher effective SNR for specific channelized applications like LTE carrier aggregation without increasing analog front-end complexity.

What digital output interfaces does the ADS62C17IRGCR support?

The ADS62C17IRGCR supports two mutually exclusive digital output modes: DDR LVDS (with 100 Ω differential termination and 1.0–1.4 V common-mode voltage) and parallel CMOS (1.7–1.9 V DRVDD, offset binary or 2's complement format). Interface selection is controlled via the SEN pin in parallel configuration mode - no register programming required for basic operation.

What is the power consumption of the ADS62C17IRGCR at full 200 MSPS operation?

At 200 MSPS, the ADS62C17IRGCR consumes 1.1 W total: 865 mW analog power (IAVDD = 262 mA at AVDD = 3.3 V) and 216–306 mW digital power depending on LVDS or CMOS interface selection. In global power-down mode, consumption drops to 45–75 mW - enabling rapid low-power states in burst-mode communication systems.
