ICS8545AG-02LF
Block Diagram
General Description
provides a low power, low noise, solution for distributing clock signals
over controlled impedances of 100Ω. The ICS8545I-02 accepts an
LVCMOS/LVTTL input level and translates it to 3.3V LVDS output
levels.
Guaranteed output and part-to-part skew characteristics make the
ICS8545I-02 ideal for those applications demanding well defined
performance and repeatability.
