Texas Instruments ADS62P42IRGCT

Overview

ADS62P42IRGCT from Texas Instruments is a dual-channel, 14-bit analog-to-digital converter with 65 MSPS maximum sample rate, DDR LVDS or parallel CMOS outputs, internal reference, and integrated digital processing block (offset correction, fine gain, decimation, 24-tap filters). It operates over –40°C to 85°C and targets radar front-ends requiring low crosstalk and high SFDR at IF frequencies.

For engineers reviewing the ADS62P42IRGCT datasheet, ADS62P42IRGCT pinout, ADS62P42IRGCT application, or ADS62P42IRGCT equivalent, this page delivers verified electrical specs (74.7 dBFS SINAD @ 10 MHz, 94 dBc SFDR, 515 mW analog power), package mapping (64-QFN, RGC), functional pin definitions, and two validated alternative parts for sampling-rate-constrained systems.

Technical Context

The ADS62P42IRGCT implements a dual-sampling architecture with independent channel A/B analog paths, each featuring a track-and-hold amplifier and 14-bit SAR+pipeline hybrid conversion. Its digital processing block supports programmable fine gain (0.05 dB steps), decimation by 2/4/8, and configurable 24-tap FIR filtering-enabling trade-offs between SNR and bandwidth without external DSP.

It accepts differential analog inputs up to 2 V_PP with 450 MHz input bandwidth and supports multiple clock types (LVPECL, LVDS, LVCMOS, sine) down to 400 mV_PP. The device includes a clock duty cycle stabilizer and offers selectable output interfaces: DDR LVDS (with CLKOUTP/M) or multiplexed/parallel CMOS, with latency as low as 10 clock cycles in low-latency mode.

FAQ

What is the maximum sampling frequency supported by ADS62P42IRGCT?

The ADS62P42IRGCT supports a maximum sampling frequency of 65 MSPS, as specified in its datasheet and confirmed across all operating conditions (–40°C to 85°C, AVDD = 3.3 V). This rating is fixed per the ADS62P4X family segmentation-ADS62P42IRGCT is the 65 MSPS variant, distinct from ADS62P43 (80 MSPS), ADS62P44 (105 MSPS), and ADS62P45 (125 MSPS). Exceeding 65 MSPS violates AC specifications and may cause aliasing or timing violations.

Does ADS62P42IRGCT include an internal voltage reference?

Yes, ADS62P42IRGCT 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 (1.45–1.55 V range). Internal reference mode eliminates external reference ICs and associated decoupling capacitors, simplifying layout and reducing BOM count-confirmed in the "Reference Voltages" section of the SLAS561C datasheet.

What digital output interfaces does ADS62P42IRGCT support?

ADS62P42IRGCT supports two mutually exclusive digital output interfaces: DDR LVDS (using CLKOUTP/M and DA0–DA13/DB0–DB13) and parallel CMOS (same data pins, no CLKOUT). Configuration is controlled by analog voltage on the SEN pin. DDR LVDS enables high-speed, low-EMI transmission; parallel CMOS offers direct FPGA compatibility with 1.8–3.3 V logic levels. Multiplexed CMOS mode is also available for reduced pin count.

What is the typical power consumption of ADS62P42IRGCT at maximum sample rate?

At 65 MSPS, ADS62P42IRGCT consumes 515 mW of analog power (AVDD = 3.3 V) and 18 mW of digital power (DRVDD = 1.8 V, CMOS interface, no external load), totaling 533 mW. With LVDS interface and 100-Ω termination, digital power rises to 73 mW (total ~588 mW). These values are measured per the SLAS561C datasheet's "POWER SUPPLY" table and reflect worst-case industrial temperature operation.

Is ADS62P42IRGCT pin-compatible with other devices in the ADS62P4X family?

Yes, ADS62P42IRGCT is fully pin-compatible with ADS62P43IRGCT, ADS62P44IRGCT, and ADS62P45IRGCT-all use the same 64-QFN (RGC) package and identical pin assignments for analog inputs, clocks, power, and digital I/O. This allows hardware reuse across sampling rate tiers; only firmware and layout tuning for thermal/power are needed when upgrading within the family.
