Networking & 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.
