Product details
Overview
ADS5520EVM from Texas Instruments is an evaluation module designed to characterize the ADS5520 12-bit, 125 MSPS analog-to-digital converter under real-world signal, clock, and power conditions. It supports transformer-coupled and differential amplifier input paths, dual-clock interface options (transformer, true differential, or ECL), and provides full digital output access via a 40-pin header for logic analyzer capture.
For engineers reviewing the ADS5520EVM datasheet, ADS5520EVM pinout, ADS5520EVM application, or ADS5520EVM equivalent, this page delivers verified technical context, confirmed hardware configuration options, supported ADC device variants, physical layout details, and supply-chain support for high-speed data acquisition system development.
Technical Context
The ADS5520EVM implements dual analog input architectures: one path uses a THS4503ID differential amplifier (U2) with configurable common-mode voltage via SJP1; the other uses Mini-Circuits TC4-1W transformers (T1/T2) for passive AC-coupled differential signaling. Input signal routing is jumper-selectable with no soldering required.
Three clock input modes are supported: transformer-coupled (default), true differential (via SMA J3/J4), and ECL-level (using MC10EP16DT U5 driver). Digital outputs are buffered by SN74AVC16244DGGR (U7) and routed to 40-pin IDC connector J8, with dedicated output clock, 14-bit parallel data bus (LSB to MSB), overflow flag, and ground pins.

FAQ
What is the primary function of the ADS5520EVM?
The ADS5520EVM is an evaluation platform for the ADS5520 12-bit, 125 MSPS analog-to-digital converter. It enables engineers to validate performance under varying analog input configurations, clock sources, power supplies, and digital interface settings-without designing custom hardware. The ADS5520EVM includes jumpers, SMA connectors, and banana jacks to simplify setup and measurement across multiple test scenarios.
Which ADC devices does the ADS5520EVM support besides the ADS5520?
The ADS5520EVM is compatible with the full ADS55xx family: ADS5500 (14-bit, 125 MSPS), ADS5541 (14-bit, 105 MSPS), ADS5542 (14-bit, 80 MSPS), ADS5520 (12-bit, 125 MSPS), ADS5521 (12-bit, 105 MSPS), and ADS5522 (12-bit, 80 MSPS). All share identical pinout and PCB footprint, allowing direct substitution on the same ADS5520EVM board with only jumper and bias adjustments.
How is analog input configured on the ADS5520EVM?
Analog input on the ADS5520EVM is configurable via jumpers and component placement. Transformer coupling (default) uses SMA J7 and requires R22/R35 removal + R41/R45 installation. Differential amplifier mode uses SMA J1/J2 and requires R22/R35 installation + R41/R45 removal, with SJP1 set to pins 1–2. C12/C32/C35/R40 allow optional filtering in amplifier mode.
What clock input options does the ADS5520EVM provide?
The ADS5520EVM supports three clock input methods: (1) transformer-coupled (default, via J7), (2) true differential (via SMA J3/J4 with R31 replaced by 49.9 Ω), and (3) ECL-level (via U5 MC10EP16DT driver, enabled by installing C36/C39/C49 and configuring SJP2). Each option maintains proper termination and signal integrity for the ADS5520's clock input specifications.
Is the ADS5520EVM suitable for production use?
No-the ADS5520EVM is explicitly designated for engineering development and evaluation only. Texas Instruments states it is not fit for commercial use due to incomplete safety, EMC, and regulatory compliance measures. It lacks agency certifications (FCC, UL, CE), has open construction, and requires user responsibility for ESD protection and thermal management during operation.
