Texas Instruments ADS58H43EVM

Overview

ADS58H43EVM from Texas Instruments is an evaluation module designed to characterize the ADS58H43 - a quad-channel, 14-bit, 250-MSPS analog-to-digital converter optimized for telecommunications applications. It supports three configurable operating modes per dual-ADC block (11-bit, 11-bit SNRBoost, and 14-bit High Resolution Burst), delivers >75 dBFS SFDR at 170 MHz input, and interfaces via LVDS output with USB-based SPI control.

For engineers reviewing the ADS58H43EVM datasheet, ADS58H43EVM pinout, ADS58H43EVM application, or ADS58H43EVM equivalent, this page provides verified hardware configuration details, TSW1400 capture integration guidance, jumper-controlled power and mode selection, real-world FFT test setup procedures, and software-controlled register access for ADC evaluation in high-speed data acquisition systems.

Technical Context

The ADS58H43EVM implements a dual-block architecture: two independent ADC pairs (A/B and C/D), each configurable into distinct resolution and noise-performance modes. Power delivery uses a TPS62420 dual-output DC/DC converter feeding low-noise LDOs (TPS7A8001) to generate 3.3 V and 1.9 V rails, with jumper-selectable bypass of LDOs for direct DC/DC powering.

Signal conditioning includes transformer-coupled single-ended-to-differential analog inputs (dual 1:1 transformers), third-order bandpass filter pads, and RLCR glitch-filter networks optimized for 185 MHz center frequency. Clock input uses a 1:4 impedance-ratio transformer to boost amplitude and match 50 Ω source impedance.

FAQ

What is the primary function of the ADS58H43EVM?

The ADS58H43EVM is a dedicated evaluation module for the ADS58H43 quad-channel ADC. It provides complete signal conditioning, power regulation, LVDS data output, and USB-based SPI control to enable full characterization of the ADS58H43's 14-bit, 250-MSPS performance-including SNRBoost and High Resolution Burst modes-in real-world telecom and instrumentation applications.

Which ADC does the ADS58H43EVM support?

The ADS58H43EVM is designed exclusively for evaluating the ADS58H43 and ADS58H40 devices. Both are pin-compatible, quad-channel, 14-bit, 250-MSPS ADCs from Texas Instruments. The EVM's hardware, firmware, and GUI software are fully compatible with both parts, as confirmed in SLAU455B Section 2.2 and the ADS58H40 EVM Configuration Software documentation (SLAC533).

How does the ADS58H43EVM interface with the TSW1400 capture card?

The ADS58H43EVM connects to the TSW1400 via its Samtec HSMC LVDS connector (J5 on ADS58H43EVM ↔ J3 on TSW1400). Trigger synchronization is achieved either through SW2 pushbutton (auto-burst) or external trigger routing using SMA cables between TSW1400 SYNC1/SYNC3 outputs and EVM jumpers (J2/J11), as detailed in Sections 3.4 and Figure 13 of SLAU455B.

What power options does the ADS58H43EVM offer?

The ADS58H43EVM accepts 6 V DC input via banana jacks (J1/J2) and derives all internal voltages using a TPS62420 dual-output DC/DC converter and two TPS7A8001 low-noise LDOs. Jumpers JP2–JP6 allow selection between default LDO-regulated 3.3 V/1.9 V rails or direct DC/DC powering of the ADC, as defined in Table 1 of SLAU455B.

Can the ADS58H43EVM operate in all three ADS58H43 operating modes?

Yes - the ADS58H43EVM fully supports all three ADS58H43 operating modes per dual-ADC block: 11-bit Operating, 11-bit SNRBoost, and 14-bit High Resolution Burst. Mode selection is implemented via hardware jumpers (JP9 for SNRBoost, JP10 for HIRES) and software GUI controls, with validation data provided in Figures 11–14 of SLAU455B for 245.76 MSPS sampling.
