TLV3801EVM User's Guide
The TLV3801EVM is an evaluation board designed to evaluate the high-speed TLV3801 comparator. The
TLV3801EVM has layout options intended to make it simple to evaluate timing performance with different
measurement tools. The output of the TLV3801 is designed for low-voltage differential signals (LVDS), that
provide high-speed signals to interconnect devices such as FPGAs with minimal power dissipation.
