General Description

The 854105I is a low skew, high performance 1-to-4

LVCMOS/LVTTL-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage

Differential Signaling (LVDS), the 854105I provides a low power, low

noise solution for distributing clock signals over controlled

impedances of 100. The 854105I accepts an LVCMOS/LVTTL

input level and translates it to LVDS output levels.

Guaranteed output and part-to-part skew characteristics make the

854105I ideal for those applications demanding well defined

performance and repeatability.
