ICS650R-07ILF
NETWORKING CLOCK SOURCE
Description
The ICS650-07C is a low cost, low jitter, high performance
clock synthesizer for networking applications. Using analog
Phase-Locked Loop (PLL) techniques, the device accepts a
12.5 MHz or 25.00 MHz clock or fundamental mode crystal
input to produce multiple output clocks for networking chips,
PCI devices, SDRAM, and ASICs. The ICS650-07C outputs
all have 0 ppm synthesis error.
See the MK74CB214, ICS551, and ICS552-01 for non-PLL
buffer devices which produce multiple low-skew copies of
these output clocks.
See the ICS570, ICS9112-16/17/18 for zero delay buffers
that can synchronize outputs and other needed clocks.
