Texas Instruments ADS5562EVM

Overview

ADS5562EVM from Texas Instruments is an evaluation module designed to characterize the ADS5562 16-bit, 80-MSPS analog-to-digital converter (ADC) with DDR LVDS and parallel CMOS digital outputs. It supports transformer-coupled or THS4509-amplified differential analog input paths, single-ended clock injection via SMA, and on-board LDO-based 3.3-V/5-V power generation for ADC and support circuitry. The EVM enables high-fidelity SNR and SFDR measurement in lab-grade ADC validation setups.

For engineers reviewing the ADS5562EVM datasheet, ADS5562EVM pinout, ADS5562EVM application, or ADS5562EVM equivalent, this page delivers verified hardware configuration options, TSW1200 capture integration guidance, jumper-controlled interface modes (parallel/serial), coherent sampling setup methodology, and board-level power/analog/digital signal routing details essential for accurate high-speed ADC evaluation.

Technical Context

The ADS5562EVM implements a 6-layer FR-4 PCB layout with split ground and dedicated power planes to preserve signal integrity for 80-MSPS sampling. It routes the ADS5562's differential analog inputs through selectable paths: default 1:1 transformer coupling (T1/T2) providing 50-Ω source termination, or optional THS4509 fully differential amplifier path with configurable gain and filtering.

Digital interfacing supports dual output modes: DDR LVDS delivered to Samtec QTH-060-02-F-D-A connector J10 (for TSW1200 capture), and CMOS parallel output routed to 40-pin IDC header J5 (requires U7 SN74AVC16244DGGR installation). Control is configurable via surface-mount jumpers for parallel interface (default) or SPI serial interface using USB-connected TI ADC SPI Control Software.

FAQ

What is the primary function of the ADS5562EVM?

The ADS5562EVM is a dedicated evaluation module for the ADS5562 16-bit, 80-MSPS analog-to-digital converter. Its purpose is to provide a lab-validated hardware platform enabling accurate measurement of key performance metrics-including SNR, SFDR, and ENOB-using controlled analog input, low-jitter clocking, and calibrated digital capture paths. The ADS5562EVM does not operate as a standalone system but serves exclusively as a test vehicle for the ADS5562 IC under defined signal and power conditions.

Which ADC models does the ADS5562EVM support?

The ADS5562EVM supports both the ADS5560 (40-MSPS) and ADS5562 (80-MSPS) devices within the same ADS556x family. The specific model is selected via internal control register settings accessed through parallel or serial interface jumpers (JP9–JP12, J1–J3). No hardware modification is required to switch between ADS5560 and ADS5562 operation-the EVM accommodates both variants natively per its design and user guide SLAU260.

How is the analog input configured on the ADS5562EVM?

The ADS5562EVM offers two analog input configurations: (1) Default transformer-coupled path using T1 and T2 (1:1 ratio), delivering 50-Ω source impedance and common-mode voltage from the ADS5562's CM pin; and (2) Optional THS4509 amplifier path enabled by repositioning SJP1–SJP5 jumpers, providing 10-dB gain and user-configurable LC filtering. Jumper Table 2 in the SLAU260 guide defines exact SJP settings for each mode.

Can the ADS5562EVM be powered directly from the TSW1200EVM?

Yes-the ADS5562EVM can be powered from the TSW1200EVM via its J15 5-V output connector. This requires setting JP8 to 1–2 on the TSW1200EVM and leaving J22 open, then connecting TSW1200's J15 to ADS5562EVM's J20 (5-V) and J12 (GND) banana jacks. This eliminates need for external bench supplies and enables compact, synchronized evaluation of ADC + capture chain.

What software tools are required to configure the ADS5562EVM?

The ADS5562EVM uses TI's ADC SPI Control Software for serial register access-installed via setup.exe, communicating over USB (J17) with drivers auto-installed by Windows. For parallel interface operation (default), no software is required: configuration is set entirely via physical jumpers (JP9–JP12, J1–J3). The TSW1200 GUI is used separately for FFT capture and analysis, not device configuration.
