Texas Instruments ADS6443EVM

Overview

ADS6443EVM from Texas Instruments is an evaluation module designed to accelerate development and validation of the ADS6443 quad-channel, 14-bit, 80 MSPS analog-to-digital converter. It provides full access to all analog inputs, LVDS serial outputs, clocking, reference, and configuration interfaces, enabling rapid prototyping of high-speed IF sampling systems in base-station receivers and medical imaging equipment.

For engineers reviewing the ADS6443EVM datasheet, ADS6443EVM pinout, ADS6443EVM application, or ADS6443EVM equivalent, this module supports real-time capture at 80 MSPS with programmable LVDS serialization (1-wire/2-wire, DDR/SDR), coarse/fine gain control, internal/external reference selection, and configurable data format (MSB/LSB first, 2's complement/offset binary).

Technical Context

The ADS6443EVM implements the full signal chain for the ADS6443 ADC - including precision clock conditioning (LVPECL/LVDS/LVCMOS-compatible input down to 400 mV_PP), on-board 1.5 V common-mode bias generation, differential analog input termination, and matched-length LVDS trace routing to four dual-pair output headers. It supports both 1-wire and 2-wire LVDS interface modes, with bit clock rates up to 1.12 GHz (2-wire DDR at 80 MSPS).

Configuration is enabled via parallel jumpers (CFG1–CFG4, SEN, PDN) and optional SPI-based register programming through an onboard FTDI USB-to-serial bridge. The board includes power sequencing control, thermal monitoring, and test points for analog input signals, reference voltages, and digital timing waveforms.

FAQ

What is the primary function of the ADS6443EVM?

The ADS6443EVM is a dedicated evaluation module for the ADS6443 14-bit, 80 MSPS quad-channel ADC. It provides complete hardware implementation - including clock distribution, analog input conditioning, LVDS output routing, and configuration interface - to enable functional verification, performance characterization, and firmware integration of the ADS6443 in real-world signal chains. The ADS6443EVM does not contain the ADS6443 IC itself but is designed exclusively for its evaluation.

Does the ADS6443EVM support both 1-wire and 2-wire LVDS output modes?

Yes, the ADS6443EVM supports both 1-wire and 2-wire LVDS serialization as defined in the ADS6443 datasheet. Configuration is achieved via on-board jumpers (CFG1) and can be changed without soldering. In 2-wire mode, the ADS6443EVM routes separate DA/DB and DC/DD LVDS pairs with matched trace lengths and controlled impedance (100 Ω differential), enabling reliable capture at bit clock rates up to 1.12 GHz.

Can the ADS6443EVM operate with an external reference voltage?

Yes, the ADS6443EVM provides direct access to the REF_P and REF_M pins of the ADS6443 socket, allowing connection of an external reference source. The board also supports internal reference operation (1.0 V to 2.0 V) and includes jumpers to select reference mode via the SEN pin voltage level, consistent with ADS6443's parallel configuration scheme.

What clock input types are compatible with the ADS6443EVM?

The ADS6443EVM accepts LVPECL, LVDS, LVCMOS, and sine-wave clock inputs - matching the ADS6443's flexible clock interface. Input amplitude ranges from 400 mV_PP (minimum) to 1.5 V_PP (sine), with AC coupling and on-board termination. Clock jitter performance is preserved via low-noise layout and dedicated ground planes, supporting aperture jitter <250 fs RMS as specified for the ADS6443.

Is software provided with the ADS6443EVM for data capture and analysis?

Texas Instruments provides the HSDC Pro software suite - compatible with the ADS6443EVM - for real-time data capture, FFT analysis, histogram plotting, and SNR/SFDR calculation. The software communicates via the onboard FTDI USB interface and supports register-level configuration of the ADS6443, including gain settings, data format, and LVDS interface options. This enables full validation of ADS6443EVM functionality without custom firmware development.
