Description
The PI6CL10804 is a 1.2V or 1.5V high-speed, low-noise
1:4 non-inverting clock buffer. The key goal in designing the
PI6CL10804 is to target networking applications that require
low-skew, low-jitter, and high-frequency clock distribution.
Providing output-to-output skew as low as 100ps, the PI6CL10804
is an ideal clock distribution device for synchronous systems. De-
signing synchronous networking systems requires a tight level of
skew from a large number of outputs.
