Texas Instruments ADS62P19EVM

Overview

ADS62P19EVM from Texas Instruments is an evaluation module designed to accelerate development with the ADS62P19 dual-channel, 11-bit, 250-MSPS analog-to-digital converter. It provides full access to LVDS and parallel CMOS digital outputs, supports programmable gain up to 6 dB, includes DC offset correction, and operates across –40°C to +85°C for wideband communication system prototyping.

For engineers reviewing the ADS62P19EVM datasheet, ADS62P19EVM pinout, ADS62P19EVM application, or ADS62P19EVM equivalent, this module enables rapid validation of high-speed ADC interface timing, clock jitter sensitivity, SNR/SFDR trade-offs under real-world RF front-end conditions, and DDR LVDS signal integrity in multi-carrier baseband receivers.

Technical Context

The ADS62P19EVM implements a complete reference design around the ADS62P19 IC, featuring matched 50-Ω differential analog input paths, on-board low-jitter clock conditioning (supporting 400 mV_PP differential input), configurable termination for both LVDS (100 Ω) and CMOS (10 pF max load) output interfaces, and selectable internal/external reference routing via jumpers.

It integrates TI's standard EVM architecture with onboard power sequencing (AVDD = 3.3 V, DRVDD = 1.8 V), thermal monitoring, serial register configuration via USB-to-SPI adapter (not included), and test points for all critical signals - including CLKP/CLKM, INP_A/INM_A, DA[10:0]/DB[10:0], and CLKOUTP/CLKOUTM - enabling direct oscilloscope probing without signal degradation.

FAQ

What is the primary function of the ADS62P19EVM?

The ADS62P19EVM is a dedicated evaluation module for the ADS62P19 dual-channel, 11-bit, 250-MSPS analog-to-digital converter. It provides a fully tested hardware platform with calibrated analog input paths, configurable digital output interfaces (LVDS/CMOS), clock conditioning circuitry, and serial register access - enabling engineers to characterize dynamic performance (SNR, SFDR, IMD), validate timing margins, and integrate the ADS62P19 into system-level designs without custom PCB development.

Does the ADS62P19EVM support both LVDS and CMOS output modes simultaneously?

No, the ADS62P19EVM supports either DDR LVDS or parallel CMOS output mode per configuration - selected via onboard jumpers and serial register settings. The ADS62P19 IC itself does not support concurrent LVDS and CMOS outputs; the EVM routes one interface at a time to maintain signal integrity and avoid contention. Mode selection must be finalized before power-up to ensure correct termination and timing alignment.

Can the ADS62P19EVM operate with an external clock source below 80 MSPS?

Yes, the ADS62P19EVM supports low-speed operation down to 1 MSPS when the ADS62P19's low-speed mode is enabled via serial register bit ENABLE LOW SPEED MODE. This setting adjusts internal timing parameters and allows stable operation with reduced clock amplitude (≥400 mV_PP) and relaxed setup/hold requirements - verified per Table 2 and Table 3 in the ADS62P19 datasheet SLAS937.

What power supplies are required to operate the ADS62P19EVM?

The ADS62P19EVM requires a single +5-V DC input (via barrel jack or USB), which it internally regulates to generate AVDD = 3.3 V and DRVDD = 1.8 V for the ADS62P19 IC. All voltage rails are monitored and sequenced per TI's recommended power-up order (AVDD leads DRVDD), and the board includes overcurrent protection and thermal shutdown circuitry to safeguard the ADS62P19 during bench testing.

Is the ADS62P19EVM compatible with TI's ADCPro™ software?

Yes, the ADS62P19EVM is fully supported by TI's ADCPro™ software suite (v6.0+). When used with the optional USB-based data capture card (TIDA-00023 or similar), ADCPro™ enables real-time FFT analysis, histogram plotting, ENOB calculation, and automated SNR/SFDR measurement - directly leveraging the ADS62P19EVM's onboard clock distribution and digital output routing to deliver production-grade characterization data.
