PRELIMINARY INFORMATION
The ICS614-01 is a low cost, low jitter, high
performance clock synthesizer for Intel’s i752
graphics systems. It includes frequencies for video
encoders and decoders. Using analog Phase-
Locked Loop (PLL) techniques, the device accepts
a 27 MHz fundamental mode crystal or clock
input to produce multiple output clocks. The chip
provides highly accurate video encoder and
decoder clocks, as well as the 48 MHz necessary
for the Intel graphics processor, and can produce a
24.576 MHz audio clock.
See the ICS604 or ICS513 for 8 pin devices that
supply 48 MHz from a 14.31818 MHz input.
