Texas Instruments ADS5410EVM

Overview

ADS5410EVM from Texas Instruments is an evaluation module designed to characterize the ADS5410 12-bit, 105-MSPS analog-to-digital converter under real-world signal, clock, and supply conditions. It supports transformer-coupled and differential-amplifier analog inputs, dual-clock routing (ADC clock and buffered output clock), and 1.8-V/3.3-V configurable digital I/O levels via SN74AVC16244 buffers.

For engineers reviewing the ADS5410EVM datasheet, ADS5410EVM pinout, ADS5410EVM application, or ADS5410EVM equivalent, this module enables rapid validation of high-speed ADC performance in test instrumentation, communications receivers, and radar front-ends - with full jumper-configurable input topology, clock path options, and power domain isolation.

Technical Context

The ADS5410EVM implements a 4-layer FR-4 PCB (104 mm × 114 mm) with dedicated analog/digital ground planes and independent banana-jack power inputs for AVDD (+3.3 V), DVDD (+1.8 V), DRVDD (+1.8 V or +3.3 V), and ±5 V analog supplies. Signal integrity is maintained via SMA connectors (J1–J4, J12, J16), on-board THS4503 differential driver, and AC-coupled 50-Ω terminated analog paths.

Circuit flexibility is achieved through three-position jumpers (W1, W3, W6) for reference selection (internal/external), common-mode voltage configuration, and power-down control, plus two-pin jumpers (R36–R39, R43–R44, R62) enabling reconfiguration between transformer-coupled and amplifier-based input topologies and clock routing modes.

FAQ

What is the primary function of the ADS5410EVM?

The ADS5410EVM is a Texas Instruments evaluation module built to assess the performance of the ADS5410 12-bit, 105-MSPS analog-to-digital converter. It provides configurable analog input paths (transformer-coupled or differential-amplifier), dual-clock routing, level-shiftable digital outputs, and isolated power domains - all implemented on a validated 4-layer PCB layout per SLAU082 User's Guide. The ADS5410EVM enables accurate characterization of dynamic parameters like SNR, SFDR, and ENOB under user-controlled signal and timing conditions.

Does the ADS5410EVM support both single-ended and differential analog inputs?

Yes, the ADS5410EVM supports both configurations via hardware-selectable jumpers. For transformer-coupled differential input, connect the signal to SMA J2 and install R37/R39 while removing R36/R38. For differential-amplifier input from a single-ended source, connect to SMA J1 and install R36/R38 while removing R37/R39. Both paths include 50-Ω termination and are AC-coupled, as specified in the SLAU082 User's Guide section 3.1.1.

How is clock routing configured on the ADS5410EVM?

The ADS5410EVM separates ADC clock and output buffer clock paths to enable precise timing control. The ADC clock can be applied differentially (J3/J16) or single-ended (J3 only), with optional transformer T2 or direct connection. The buffered output clock is driven from SMA J4 and routed to J15 pin 29; jumpers R43/R44 select whether the ADC clock or an external signal drives this output. This architecture allows users to adjust phase alignment and meet setup/hold requirements for downstream logic analyzers or FPGAs.

What power supplies are required to operate the ADS5410EVM?

The ADS5410EVM requires four independent power sources: +3.3 V for analog circuitry (J6/J5), +1.8 V for digital core (J9/J10), +1.8 V or +3.3 V for digital drivers (J13/J14), and ±5 V for the THS4503 differential amplifier (J7/J8/J11). These are delivered via banana jacks with dedicated return paths. Supply sequencing is not mandated, but stable regulation and low-noise operation are essential for optimal ADC performance per SLAU082 Section 1.3.

Can the ADS5410EVM be used with external reference sources?

Yes - jumper W1 selects between internal and external reference. With pins 2–3 installed, the ADS5410EVM uses its internal 2.15-V reference (VREFT/VREFB). To use an external reference, remove W1 and connect to REFT/REFB test points (TP7/TP8) per schematic Sheet A3. External reference must comply with ADS5410 datasheet specifications: 1.65 V to 2.5 V, low noise (<10 µV RMS), and capable of sourcing/sinking ≥1 mA. This option is confirmed in SLAU082 Section 3.1.3 and Table 1–2.
