1:4 24MHz Clock Buffer
Description
The PI6C490094 is a low jitter clock buffer supporting either
XTAL or reference input. Two of its outputs can support wide
operating voltage from 1.8V to 3.3V. It is a cost effective way to
generate multiple outputs for all kinds of applications that need
24MHz with different power supplies.
