Overview
This ADS5400EVM-CVAL user's guide gives an overview of the EVM and provides a general description
of the features and functions to be considered while using this module.
1.1
Purpose
The ADS5400EVM-CVAL provides a platform for evaluating the ADS5400HFS/EM device under various
signal, reference, and supply conditions. Use this document along with the EVM schematic diagram
supplied.
1.2
EVM Quick-Start Procedure
Power Supply
Power connections to the EVM are supplied by banana jack sockets.
Clock
The EVM provides an external SMA connector for input of the ADC clock. The single-ended input is
converted into a differential signal at the input of the device.
Analog Inputs
The analog input to the ADC is provided by a external SMA connector. The user supplies a single-ended
input or differential input (SMA connector which is not populated in the EVM). If the single-ended
configuration is used, the signal is converted into the differential signal before the ADC.
1.3
Power Requirements
The EVM can be powered directly from 5 V for the ADC analog supply, or EVM jumper settings can be
modified to use the onboard power solution from Texas Instruments (TI). The input power supply voltage
range for the EVM can be 6 V to 36 V only if the onboard TI power solution is used.
1.4
ADS5400EVM-CVAL Operational Procedure
The ADS5400EVM-CVAL provides a flexible means of evaluating the ADS5400HFS/EM in various modes
of operation. A quick-setup procedure follows.
1. Verify all jumper settings according to the schematic jumper list in
