Texas Instruments ADS5463EVM-CVAL

Overview

ADS5463EVM-CVAL from Texas Instruments is a dedicated evaluation module for the ADS5463 13-bit, 500-MSPS analog-to-digital converter (ADC), supporting differential analog input via SMA connectors, LVDS digital output via high-density Samtec header, and flexible clocking with up to 500 MHz single-ended input converted to differential. It enables performance validation under varied signal, reference, and supply conditions in high-speed data acquisition systems.

For engineers reviewing the ADS5463EVM-CVAL datasheet, ADS5463EVM-CVAL pinout, ADS5463EVM-CVAL application, or ADS5463EVM-CVAL equivalent, this page delivers verified technical context, power configuration guidance, analog/digital interface details, clock conditioning topology, and layout-specific design considerations for rapid ADC characterization and system integration.

Technical Context

The ADS5463EVM-CVAL implements dual analog input paths: one using THS9000 RF amplifiers for active differential drive, and another ac-coupled via MACOM ETC1-1-13 balun for transformer-based signal conditioning. Both accept single-ended sources and convert them to differential signals compliant with the ADS5463's input requirements.

Digital output uses LVDS signaling routed through a 60-pin Samtec QTH-060-02-F-D-A header (J5), requiring external 100-Ω termination per data pair. Clock input at J17 passes through Coilcraft WBC4-1W transformer for differential conversion and voltage step-up (2×), with strict ≤500 MHz frequency limit and 50-Ω source impedance requirement.

FAQ

What is the primary function of the ADS5463EVM-CVAL?

The ADS5463EVM-CVAL is a Texas Instruments evaluation module built to characterize the ADS5463 13-bit, 500-MSPS analog-to-digital converter. It provides complete signal chain support-including configurable analog input paths, differential clock conditioning, LVDS digital output routing, and discrete power supply inputs-enabling engineers to validate ADC performance under real-world signal, timing, and supply conditions without custom PCB development. The ADS5463EVM-CVAL is not a standalone product but a hardware reference platform for the ADS5463 IC.

Which ADC does the ADS5463EVM-CVAL support, and is it compatible with other variants?

The ADS5463EVM-CVAL is specifically configured and validated for the ADS5463, though its layout supports family migration to ADS5444 and ADS5474 via jumper reconfiguration (e.g., J20 selects 3.3 V for ADS5463/74 vs. 5 V for ADS5444). Pin compatibility and power sequencing differ across variants; therefore, direct substitution without verifying jumper settings, decoupling, and signal routing is not supported. The ADS5463EVM-CVAL does not natively support non-SP (space-grade) or unrelated ADC families.

What are the required power supplies for operating the ADS5463EVM-CVAL?

The ADS5463EVM-CVAL requires three externally supplied voltages delivered via banana jacks: 5 V (±2.5%) to J12 for ADC analog supply (AVDD), 3.3 V (±10%) to J14 for second analog rail (AVDD), and 3.3 V (±10%) to J7 for digital buffer supply (DVDD). All returns connect to AGND via J8, J9, or J19. No onboard regulators are present - each rail must be low-noise, well-decoupled, and independently controlled to meet ADS5463's stringent PSRR and jitter sensitivity requirements.

How is the clock signal conditioned on the ADS5463EVM-CVAL?

The ADS5463EVM-CVAL accepts a single-ended clock up to 500 MHz at SMA connector J17, which feeds into a Coilcraft WBC4-1W 1:4 impedance-ratio transformer. This component converts the input to differential format while stepping up the voltage by 2× - meaning a 1-Vpp input yields ~2-Vpp differential swing at the ADS5463 CLKP/CLKM pins. Proper 50-Ω source termination is mandatory; exceeding 500 MHz or applying excessive voltage risks ADC damage or degraded aperture jitter performance.

Can the ADS5463EVM-CVAL be used with standard logic analyzers, and what output configuration is needed?

Yes, the ADS5463EVM-CVAL's LVDS outputs are accessible via J5 (Samtec QTH-060-02-F-D-A), and TI supplies a compatible logic analyzer breakout board with integrated 100-Ω terminations. To capture valid data, the logic analyzer must be configured for DDR mode using the DRY clock (DRYP/DRYM), and signal assignments must follow Table 3 in the SLAU457A User's Guide - e.g., D[12] maps to MSB-11_P and corresponds to LSB for ADS5463. Misalignment or missing termination causes data corruption or timing violations.
