The ICS604 is the most cost effective way to
generate high quality, high frequency clocks for
Intel’s latest generation of graphics controllers. It
provides 48 MHz for the graphics controller, a
24.576 MHz clock for video or audio, as well as a
14.31818 MHz buffered output for the system
clock. Using patented Phase-Locked-Loop (PLL)
techniques, the ICS604 requires only a standard
fundamental mode, inexpensive crystal.
ICS makes additional devices to meet multiple
graphic system requirements. If the 24.576 MHz
clock is not needed, use the ICS513. If additional
frequencies are required for different video
encoders and decoders, see the ICS614-01.
