Description
The PI6C10810 is a 1.2V to 2.5V high-speed, low-noise
1-10 non-inverting clock buffer. The key goal in designing the
PI6C10810 is to target networking applications that require low-
skew, low-jitter, and high-frequency clock distribution.
Providing output-to-output skew as low as 60ps, the PI6C10810
is an ideal clock distribution device for synchronous systems.
Designing synchronous networking systems requires a tight level
of skew from a large number of outputs.
