Texas Instruments ADS5440EVM

Overview

ADS5440EVM from Texas Instruments is an evaluation module designed to characterize the ADS5440 13-bit, 210-MSPS analog-to-digital converter under real-world signal, clock, and supply conditions. It supports dual analog input paths (balun-coupled and THS9001 amplifier-based), differential LVDS digital output via high-density Samtec header, and flexible power configuration using banana jack inputs for 3.3-V and 5-V supplies.

For engineers reviewing the ADS5440EVM datasheet, ADS5440EVM pinout, ADS5440EVM application, or ADS5440EVM equivalent, this page provides verified technical context, key specifications, availability status, manufacturer background, and answers to common integration questions specific to ADC evaluation platform setup and signal integrity validation.

Technical Context

The ADS5440EVM implements a 6-layer FR-4 PCB layout optimized for high-speed ADC evaluation, featuring separate analog/digital power planes, controlled-impedance LVDS routing, and dual-input signal conditioning paths. It accommodates ADS5440/44/63/74 family devices via jumper-selectable configurations (e.g., J20 for 5-V vs. 3.3-V digital buffer supply).

Signal path options include transformer-coupled (ETC1-1-13 balun) and active amplifier (THS9001) inputs, both converting single-ended sources to differential drive for the ADC. Clock input at J17 accepts up to 500 MHz single-ended signals, converted to differential via Coilcraft WBC4-1W transformer with 2× voltage gain.

FAQ

What is the primary function of the ADS5440EVM?

The ADS5440EVM is a hardware evaluation platform for the ADS5440 13-bit, 210-MSPS analog-to-digital converter. It enables engineers to validate ADC performance-including SNR, SFDR, and ENOB-under controlled analog input, clock, and power conditions. The ADS5440EVM supports both balun-coupled and THS9001 amplifier-based signal paths and provides LVDS digital output for oscilloscope or logic analyzer capture.

Which ADC variants does the ADS5440EVM support besides the ADS5440?

The ADS5440EVM supports the full ADS5440/44/63/74 family via jumper configuration. Jumper J20 selects between ADS5440/44 (pins 1–2 shorted for 5-V digital buffer) and ADS5463/74 (pins 2–3 shorted for 3.3-V digital buffer). JP3 and JP4 configure analog input routing, while J21 enables ADS5474 power-down mode. The ADS5440EVM PCB footprint and netlist are shared across all four devices.

How is the clock signal conditioned on the ADS5440EVM?

The ADS5440EVM accepts a single-ended clock up to 500 MHz at SMA connector J17. This signal is converted to differential format using the Coilcraft WBC4-1W transformer, which provides a 4:1 impedance ratio and steps up input voltage by 2×. The resulting differential clock drives the CLKP/CLKM pins of the ADS5440, ensuring low-jitter timing critical for high-resolution sampling performance.

What power supplies are required to operate the ADS5440EVM with the ADS5440?

To operate the ADS5440EVM with the ADS5440, three regulated supplies are required: 5 V (±2.5%) applied to J12 (AVDD), 3.3 V (±10%) applied to J14 (AVDD) and J7 (DVDD), and AGND returns via J8, J9, and J19. When using the THS9001 amplifier path, an additional 5-V supply must be connected to J18. All voltages must remain within specified limits to prevent damage or malfunction of the ADS5440EVM.

Can the ADS5440EVM be used with logic analyzers, and what breakout support is provided?

Yes-the ADS5440EVM includes a dedicated touchless probe breakout board compatible with Agilent E5405A and Tektronix P6980 high-speed logic analyzers. The breakout board provides on-board 100-Ω LVDS terminations at the probe point and maps J5 output signals (D0–D15, DRY clock, OVR) to standard logic analyzer channel assignments. DDR-mode clocking is required for proper data capture, and Table 3 in the SLAU194A User's Guide defines default signal-to-channel mappings for the ADS5440EVM.
