Description
The PI6C49014 is a high performance networking clock
generator which generates 200MHz HCSL clock signal along
with two LVCMOS 25MHz and 32.256MHz clocks from either
25MHz crystal or reference input. This integrated solution is ideal
for Networking and Embedded systems that require multiple
frequencies yet small foot print.
