Overview
1.1 Purpose
The TLC5540/TLC5510/TLC5510A/TLV5540/TLV5510 evaluation module
(EVM) provides a platform for lab prototype evaluation of the Texas Instru-
ments TLC5540/TLC5510/TLC5510A/TLV5540/TLV5510 8-bit, high-speed
analog-to-digital converters.
Since practical operation can be acheived in excess of 40 MHz, the circuit
layout is critical and does not lend itself to classic breadboarding techniques.
In fact, proper operation requires use of surface-mount components.

Overview
1.2 Power Supply Requirements
The TLC5540/TLC5510/TLC5510A/TLV5540/TLV5510 EVM is designed to
be powered by regulated lab power supplies. Three lab supplies are required
for the best performance.

The digital supply uses an isolated ground plane.
The two ground planes can be easily connected by soldering jumpers from
E21 to E22 or from E13 to E14. This allows the user to adapt the EVM to
various grounding conditions that can exist in an evaluation circuit interface.
