Texas Instruments ADS58B19EVM

Overview

ADS58B19EVM from Texas Instruments is an evaluation module designed to characterize the ADS58B19, a 12-bit, 250-MSPS analog-to-digital converter (ADC) with LVDS parallel output, used in high-speed data acquisition, communications infrastructure, and instrumentation systems. It supports transformer-coupled single-ended analog input, external or onboard clocking (via CDCE72010 + VCXO), dual 1.8-V analog/digital supplies, and SPI register control.

For engineers reviewing the ADS58B19EVM datasheet, ADS58B19EVM pinout, ADS58B19EVM application, or ADS58B19EVM equivalent, this page details its configurable power architecture (TPS62562 buck / TPS79618 LDO), clock interface options (direct SMA, crystal-filtered LVCMOS, differential LVPECL), analog input paths (J6 transformer or THS4509 amplifier), LVDS digital output termination, and compatibility with TI's HSDC Pro and TSW1400 capture platform.

Technical Context

The ADS58B19EVM implements a modular signal chain: analog input is conditioned via Mini-Circuits ADT4-1WT transformer (1:1 ratio, 50-Ω matched) or THS4509 differential amplifier; clocking supports three modes - direct 250-MHz sinusoidal input at J19, 245.76-MHz crystal-filtered LVCMOS output from CDCE72010 (configured for ÷4 of 983.04-MHz VCXO), or differential LVPECL output from CDCE72010 Y1P/Y1N pins.

Power delivery is fully configurable: 3.3-V input at J16 feeds either TPS62562 (buck, high-efficiency) or TPS79618 (LDO, low-noise) to generate isolated 1.8-V analog (1.8VA) and digital (1.8VD) rails; jumper-selectable supply paths (JP13/JP14/JP17/JP19) enable current isolation for precise ADC power consumption measurement.

FAQ

What is the primary function of the ADS58B19EVM?

The ADS58B19EVM is a dedicated evaluation module for the ADS58B19 12-bit, 250-MSPS analog-to-digital converter. Its purpose is to enable comprehensive performance characterization-including SNR, SFDR, and ENOB-under real-world conditions involving variable clock sources, analog input configurations (transformer or THS4509 amplifier), power supply topologies, and LVDS data capture. The ADS58B19EVM provides full hardware configurability via jumpers and surface-mount zero-ohm resistors to match diverse test requirements without PCB redesign.

Which ADC does the ADS58B19EVM evaluate?

The ADS58B19EVM evaluates the ADS58B19, a Texas Instruments 12-bit, 250-MSPS analog-to-digital converter featuring LVDS parallel output, on-chip reference, and optimized architecture for IF sampling in communications and instrumentation. While the EVM user guide references ADS41xx and ADS58B18 devices, the ADS58B19EVM is a distinct, pin-compatible variant within the same platform family, validated for ADS58B19-specific timing, power, and interface behavior per TI documentation SLWU067D.

How is clocking configured on the ADS58B19EVM?

The ADS58B19EVM supports three clocking modes: (1) Direct 250-MHz single-ended sine wave applied to SMA connector J19, converted to differential by ADT4-1WT transformer; (2) Onboard 245.76-MHz LVCMOS clock from CDCE72010 (factory-configured ÷4 of 983.04-MHz VCXO), filtered through a 245.76-MHz crystal filter; (3) Differential LVPECL clock from CDCE72010 Y1P/Y1N outputs. Configuration is controlled by jumpers JP1, JP4, R81/R107, R113–R115, and R108/R110 as documented in Tables 2-3 and 2-4 of the ADS58B19EVM user guide.

What power supply options does the ADS58B19EVM support?

The ADS58B19EVM supports three power configurations: (1) Single 3.3-V input at J16 powering TPS62562 buck regulator to generate both 1.8VA and 1.8VD rails (highest efficiency); (2) Same 3.3-V input powering TPS79618 LDO for lower noise and higher PSRR; (3) Isolated external 1.8-V supplies for AVDD and DVDD, enabled by removing shunts on JP13/JP14 and supplying voltage to their center posts. All options are selected via jumpers JP13, JP14, JP17, and JP19 per Table 2-2.

Can the ADS58B19EVM be used with the TSW1400 capture board?

Yes, the ADS58B19EVM is fully compatible with the TI TSW1400 high-speed data capture board. When connected to J10 (LVDS output connector), the TSW1400 automatically applies proper 100-Ω differential termination to all LVDS data pairs and DCO. Data capture and analysis are performed using TI's HSDC Pro software, which supports FFT, histogram, and spectral analysis for the ADS58B19 under test. This integration is explicitly validated in Section 4 ("Quick Start Setup") and Section 5 ("Evaluation") of the ADS58B19EVM user guide.
