ABSTRACT
The TLV3811EVM is an evaluation board designed to evaluate the high-speed TLV3811 comparator. The
TLV3811EVM has layout options intended to make it simple to evaluate timing performance with different
measurement tools. The output of the TLV3811 is designed for low-voltage differential signals (LVDS) that
provide high-speed signals to interconnect devices such as FPGAs with minimal power dissipation.
