Texas Instruments ADS58H40EVM

Overview

ADS58H40EVM from Texas Instruments is an evaluation module designed to characterize the ADS58H40 - a quad-channel, 14-bit, 250-MSPS analog-to-digital converter optimized for telecommunications applications. It supports three configurable operating modes per ADC pair (11-bit, 11-bit SNRBoost, and 14-bit High-Resolution Burst), delivers >75 dBFS SFDR at 170 MHz input, and interfaces via LVDS outputs to capture platforms like the TSW1400.

For engineers reviewing the ADS58H40EVM datasheet, ADS58H40EVM pinout, ADS58H40EVM application, or ADS58H40EVM equivalent, this page provides verified hardware configuration details, software control workflow, test setup guidance, and integration notes with TI's High-Speed Data Converter Pro GUI and TSW1400 capture card - all critical for ADC performance validation in baseband receiver and wideband instrumentation designs.

Technical Context

The ADS58H40EVM implements a dual-block architecture: two independent ADC pairs (A/B and C/D), each configurable for distinct resolution and noise-performance trade-offs. Each block accepts transformer-coupled single-ended or differential analog inputs and a dedicated SMA clock input routed through a 1:4 impedance-ratio transformer to ensure optimal clock amplitude and jitter performance.

Power delivery uses a 6-V input feeding a dual-output DC/DC converter (TPS62420) followed by low-noise LDOs (TPS7A8001) generating 3.3 V and 1.9 V for the ADS58H40. Jumper-selectable configurations allow bypassing LDOs for direct DC/DC supply to the ADC, enabling efficiency vs. noise optimization.

FAQ

What is the primary function of the ADS58H40EVM?

The ADS58H40EVM is a dedicated evaluation module for the ADS58H40 quad-channel, 14-bit, 250-MSPS analog-to-digital converter. Its purpose is to enable engineers to validate ADC performance - including SNR, SFDR, and dynamic range - under real-world conditions using configurable analog inputs, precise clocking, LVDS data capture, and software-controlled operating modes such as SNRBoost and High-Resolution Burst. The ADS58H40EVM itself contains no ADC silicon; it hosts and interfaces with the ADS58H40 device for lab-based characterization.

Which software tools are required to operate the ADS58H40EVM?

Two complementary software tools are required: the ADS58H40 EVM Configuration Software (SLAC533) for low-level register control and mode configuration of the ADS58H40 device, and the High Speed Data Converter Pro GUI (v1.5+) for FFT analysis, data capture, and performance reporting when used with the TSW1400 capture card. Both tools support ADS58H40 and ADS58H43 variants, and the ADS58H40EVM firmware must be loaded during initial setup to ensure proper communication and feature enablement.

How does the ADS58H40EVM support different ADC operating modes?

The ADS58H40EVM supports all three ADS58H40 operating modes per channel pair via hardware jumpers and GUI controls: 11-bit standard mode, 11-bit SNRBoost mode (enhanced SNR at cost of resolution), and 14-bit High-Resolution Burst mode (full-resolution capture triggered on demand). JP9 enables SNRBoost, JP10 and GUI settings control HIRES mode, and JP12 routes trigger signals from SW2 or TSW1400. Mode selection is validated through register writes and confirmed by LED indicators D3 (trigger-ready) and D4 (burst-active) on the ADS58H40EVM board.

Can the ADS58H40EVM be used without the TSW1400 capture card?

Yes - the ADS58H40EVM can operate standalone for basic register configuration, power sequencing verification, and analog input/clock signal integrity checks using its onboard LEDs, jumpers, and USB interface. However, full performance evaluation (e.g., FFT-based SNR/SFDR measurement) requires external data capture capability. While the TSW1400 is the reference platform, alternative FPGA-based LVDS receivers with compatible timing and framing may be used if they support the ADS58H40's DDR LVDS output format, 250-MSPS data rate, and channel alignment protocol - though TI only validates and documents the ADS58H40EVM + TSW1400 combination.

What power supply options does the ADS58H40EVM offer?

The ADS58H40EVM accepts 6-V DC input via banana jacks (J1/J2) or a 6-V power brick, and internally generates 3.3 V and 1.9 V for the ADS58H40 using either a default path (TPS62420 DC/DC → TPS7A8001 LDOs) or a bypass path (DC/DC directly to ADC). Jumpers JP2–JP6 select between these configurations, with Option #1 (default) prioritizing low-noise performance and Option #2 optimizing power efficiency. LED D1 confirms main power presence, and D2 indicates USB-to-SPI converter operation - both essential for verifying stable ADS58H40EVM power-up before initiating ADC tests.
