Product details
Overview
ADS62C17IRGCT from Texas Instruments is a dual-channel, 11-bit, 200 MSPS analog-to-digital converter featuring TI's proprietary SNRBoost technology, 90 dBc SFDR at 10 MHz input, 79.8 dBFS SNR at 125 MHz IF (20 MHz BW), and DDR LVDS/parallel CMOS output interfaces - deployed in multi-carrier wireless baseband receivers.
For engineers reviewing the ADS62C17IRGCT datasheet, ADS62C17IRGCT pinout, ADS62C17IRGCT application, or ADS62C17IRGCT equivalent, key selection considerations include channel-to-channel gain matching capability (±0.001 dB tuning), DC offset correction loop, internal/external reference support, and industrial temperature range (–40°C to 85°C) operation.
Technical Context
The ADS62C17IRGCT integrates two independent 11-bit ADC cores with sample-and-hold, digital processing blocks per channel (including SNRBoost, gain control, and DC offset correction), and configurable DDR LVDS or parallel CMOS output serializers. Clock generation and output clock buffering are embedded.
It supports programmable gain (0–6 dB in 0.5 dB steps) and fine gain tuning (0.001 dB resolution) for channel balancing, operates with differential input clock amplitudes as low as 400 mVp-p, and delivers 90 dB cross-talk up to 200 MHz - all within a single 64-QFN package with integrated thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 11-bit with no missing codes - guarantees monotonicity and deterministic code transitions across full dynamic range. |
| Max Sample Rate | 200 MSPS - enables digitization of wide instantaneous bandwidths (e.g., 100 MHz Nyquist zone) in communications systems. |
| SNR @ 125 MHz IF | 79.8 dBFS using SNRBoost - improves effective resolution by ~1.3 bits within user-defined sub-Nyquist bandwidths. |
| SFDR @ 10 MHz | 90 dBc - suppresses spurious content critical for multi-tone signal integrity in LTE/WiMAX base stations. |
| Total Power | 1.1 W at 200 MSPS - balances high-speed performance with thermal manageability in dense RF front-end layouts. |
| Analog Input BW | 700 MHz - supports direct sampling of IF signals up to UHF band without external filtering degradation. |
| Output Interface | Configurable DDR LVDS or parallel CMOS - provides layout flexibility: LVDS reduces EMI and timing skew; CMOS simplifies FPGA interfacing. |
Pinout & Package
ADS62C17IRGCT is housed in a thermally enhanced 64-pin QFN package (9 mm × 9 mm) with exposed thermal pad, optimized for high-frequency signal integrity and power dissipation in compact RF subsystems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA_P / INA_M INB_P / INB_M |
Differential analog inputs (Channel A/B) | Accept 2 Vpp differential signals with 1.5 V common-mode; support >500 MHz input frequency at full scale. |
| CLKP / CLKM | Differential input clock | Accepts LVDS/LVPECL/LVCMOS clocks; functional down to 400 mVp-p; duty cycle tolerance 40–60%. |
| VCM | Input common-mode voltage reference | Outputs 1.5 V ±0.1 V; supplies bias for analog inputs; supports external override in external reference mode. |
| DA0P/M–DA10P/M DB0P/M–DB10P/M |
DDR LVDS data outputs (Channel A/B) | Double-data-rate serialized 11-bit words; 100 Ω differential termination required; VOCM = 1.15 V typical. |
| CLKOUTP/M | LVDS output clock | Phase-aligned DDR clock for data capture; propagation delay = 0.69×Ts + 4.2–7.2 ns (200 MSPS). |
| SEN / SCLK / CTRL1–3 | Configuration interface | Parallel-mode control pins: set reference source, output format, SNRBoost enable, standby, and power-down states. |
| RESET | Hardware reset input | Active-high pulse (>10 ns) initializes registers and clears internal state; required before serial configuration. |
Key Features
| Feature | Design Value |
|---|---|
| SNRBoost technology | Enables up to +5.6 dB SNR improvement in 20 MHz bandwidth at 125 MHz IF - extends usable ENOB without increasing sampling rate. |
| Channel gain tuning | 0.001 dB resolution per channel - achieves <±2% FS gain matching between channels for coherent MIMO processing. |
| DC offset correction loop | Automatically cancels static ADC offset errors - eliminates need for external calibration in zero-IF receiver chains. |
| Internal reference | Eliminates external reference IC and decoupling capacitors - reduces BOM count and PCB area in space-constrained designs. |
| Thermal pad package | RθJA = 15 °C/W with 200 LFM airflow - sustains 1.1 W dissipation at ≤85°C ambient without heatsink. |
Applications
| Wireless Base Station Receiver | Multi-Carrier Transceiver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 11-bit, 200 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS62P15IRGCT | 15-bit resolution, 100 MSPS max, no SNRBoost - higher ENOB but half the sampling rate and no fine gain tuning. | Better for narrowband high-precision instrumentation; unsuitable for wideband comms requiring >150 MSPS. | Select when SNR > 85 dBFS is prioritized over bandwidth and channel matching. |
| AD9233BCPZ-200 | Analog Devices part: 12-bit, 200 MSPS, no integrated SNRBoost, requires external reference and clock buffer. | Higher resolution but lacks on-chip DC offset correction and gain-matching features - increases system calibration burden. | Choose if legacy ADI ecosystem integration or JESD204B interface is required; not drop-in compatible. |
Compared with ADS62C17IRGCT, ADS62P15IRGCT trades speed for precision and omits adaptive noise suppression, while AD9233BCPZ-200 demands more external components and manual calibration - making ADS62C17IRGCT optimal for cost-sensitive, high-integration wireless infrastructure designs.

FAQ
What is the maximum analog input frequency supported by the ADS62C17IRGCT?
The ADS62C17IRGCT supports up to 500 MHz analog input frequency with a 2 Vpp differential input amplitude, and up to 800 MHz with a 1 Vpp amplitude. Its 700 MHz analog input bandwidth ensures minimal signal attenuation and phase distortion across this range, enabling direct IF sampling in UHF receivers without external anti-aliasing filter penalties.
Does the ADS62C17IRGCT require an external reference voltage?
No - the ADS62C17IRGCT includes an internal reference and eliminates dedicated reference pins and decoupling capacitors. However, it also supports external reference operation via the VCM pin, allowing system designers to override the internal reference for improved accuracy or synchronization with other converters in the signal chain.
How does SNRBoost improve performance in the ADS62C17IRGCT?
SNRBoost in the ADS62C17IRGCT applies proprietary digital filtering to overcome quantization noise limitations in sub-Nyquist bandwidths. At 125 MHz IF with 20 MHz bandwidth, it delivers 79.8 dBFS SNR - a +5.6 dB gain over default mode - effectively increasing ENOB by ~1.3 bits without increasing power or sampling rate.
What output interface options does the ADS62C17IRGCT support?
The ADS62C17IRGCT supports two configurable digital output interfaces: DDR LVDS (with 100 Ω differential termination) and parallel CMOS (11-bit per channel). Selection is controlled via the SEN pin in parallel configuration mode, allowing hardware-based interface switching without firmware intervention.
Can the ADS62C17IRGCT perform channel-to-channel gain matching?
Yes - the ADS62C17IRGCT provides independent fine gain tuning for each channel in 0.001 dB steps, enabling precise channel-to-channel gain matching within ±2% FS error. This capability is essential for coherent MIMO and beamforming applications where amplitude imbalance degrades spatial processing accuracy.
