PLL Clock Multiplier
Description
The PI6C490086 is a low jitter clock generator supporting
either XTAL or reference input. Two of its buffered outputs can
support wide operating voltage from 1.8V to 3.3V. It is a cost ef-
fective way to generate multiple outputs for all kinds of applica-
tions that need 25MHz with different power supplies and a 8.192
MHz clock signal.
