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.
