Introduction

US5D2104D is a 2GHz, 8-output differential high-performance clock fanout buffer. The US5D2104D clock buffer distributes two selectable clock inputs to 8 pairs of differential LVDS clock outputs for minimum skew in clock distribution. The US5D2104D routes a single clock source into the input multiplexer. Inputs can be LVDS, LVPECL, or LVCMOS. The maximum clock frequency is up to 2GHz. This device is designed for signal fanout of high-frequency, low phase noise clock and data signals. It is designed to operate with a 2.5V/3.3V core supply and a 2.5V/3.3V output operating supply.
