TLV3802 Evaluation Module
Description
The TLV3802EVM is an evaluation board designed
to evaluate the high-speed dual channel TLV3802
comparator. The TLV3802EVM has layout options
intended to simply evaluate timing performance
with different measurement tools. The output of
the TLV3802 is designed for low-voltage differential
signals (LVDS), which provide high-speed signals to
interconnect devices such as FPGAs with minimal
power dissipation.
