Texas Instruments ADS54RF63EVM

Overview

ADS54RF63EVM from Texas Instruments is an evaluation module designed to characterize the ADS5463 13-bit, 500-MSPS analog-to-digital converter under real-world signal, clock, and supply conditions. It supports dual analog input paths (balun-coupled and THS9001 amplifier-based), differential LVDS digital output via high-density Samtec header, and flexible power configuration with independent 5-V analog, 3.3-V analog, and 3.3-V digital supplies.

Technical Context

The ADS54RF63EVM implements a 6-layer FR-4 PCB with dedicated ground and power planes optimized for high-speed ADC evaluation. It integrates two analog input signal chains: one using MACOM ETC1-1-13 baluns for broadband transformer-coupled operation (4 MHz–1 GHz), and another using TI THS9001 IF amplifiers with tunable 170-MHz band-pass filtering.

Digital output follows LVDS standards with 100-Ω termination support at J5; the board includes a touchless probe breakout board compatible with Agilent E5405A and Tektronix P6980 logic analyzers. Clock input accepts single-ended 500-MHz max sine/square wave at J17, converted to differential by Coilcraft WBC4-1W transformer with 2× voltage step-up.

FAQ

What is the primary function of the ADS54RF63EVM?

The ADS54RF63EVM is a dedicated evaluation module for the ADS5463 13-bit, 500-MSPS analog-to-digital converter. It enables engineers to validate dynamic performance metrics-including SNR, SFDR, and spurious-free dynamic range-under controlled analog input, clock, and supply conditions. The ADS54RF63EVM supports both balun-coupled and amplifier-driven signal paths and provides LVDS digital output accessible via high-density connector J5.

Which ADC devices are supported on the ADS54RF63EVM?

The ADS54RF63EVM supports multiple members of the ADS54xx family: ADS5440, ADS5444, ADS5463, and ADS5474. Jumper J20 selects between 5-V (ADS5440/44) and 3.3-V (ADS5463/74) digital buffer supply, while J21 configures ADS5474-specific power-down functionality. This shared layout allows hardware reuse across device variants without PCB redesign.

How is the clock signal conditioned on the ADS54RF63EVM?

The ADS54RF63EVM accepts a single-ended clock up to 500 MHz at SMA connector J17. A Coilcraft WBC4-1W transformer converts it to differential format required by the ADS5463, with inherent 2× voltage gain. This design ensures proper common-mode establishment and minimizes jitter contribution from clock path impedance mismatch, directly supporting high-fidelity sampling integrity for the ADS54RF63EVM.

What analog input configurations does the ADS54RF63EVM provide?

The ADS54RF63EVM offers two analog input configurations: (1) transformer-coupled path via J11 using MACOM ETC1-1-13 baluns (4 MHz–1 GHz bandwidth, <1 dB insertion loss), and (2) active path via J10 using dual THS9001 amplifiers with tunable 170-MHz band-pass filter. JP3 and JP4 jumpers select between these modes, enabling flexible front-end optimization for different frequency and dynamic range requirements on the ADS54RF63EVM.

Does the ADS54RF63EVM include logic analyzer interface support?

Yes, the ADS54RF63EVM includes a dedicated touchless probe breakout board compatible with Agilent E5405A and Tektronix P6980 logic analyzers. This board provides on-board 100-Ω LVDS terminations at the probe point and maps J5 output signals to standard logic analyzer channel assignments. When used with the ADS54RF63EVM, it eliminates external termination needs and enables reliable DDR-mode data capture synchronized to the DRY clock.
