NETWORKING AND PCI CLOCK SOURCE
Description
The ICS650-36 is a low cost frequency generator designed
to support networking and PCI applications. Using
analog/digital Phase Locked-Loop (PLL) techniques, the
device uses a standard fundamental mode, inexpensive
crystal input of 25 MHz to produce four output clocks
supporting LAN, PCI, and 100M SDRAM functions.
The device also has a power down feature that tri-states the
clock outputs and turns off the PLL when the PDTS pin is
taken low.
