1:8 LVDS Fanout Buffer with 2-Input Multiplexer for 1PPS Applications

8V34S208 Data Sheet

概要

The 8V34S208 is a differential 1:8 LVDS fanout buffer with a 2:1 input multiplexer. The device accepts DC to 250MHz clock and data signals and is designed for 1Hz clock/1PPS, 2kHz, and 8kHz signal distribution. Controlled by the input mode selection pin, the differential input stages accept both rectangular or sinusoidal signals. The 8V34S208 also provides level-translated LVCMOS/LVTTL outputs which are copies of the individual differential inputs CLKA and CLKB. The propagation delay of the device is very low, providing an ideal solution for clock distribution circuits with tight phase alignment requirements. The multiplexer select pin (SEL) allows the selection of one out of two input signals, which is copied to the four differential outputs.
