ICS411
PC PERIPHERAL CLOCK
Description
The ICS411 is a cost-effective clock synthesizer
developed to optimize component count for PC
motherboard and peripheral applications. The device
supports a common, low cost 14.31818 MHz crystal.
The device locks all output frequencies to enhance
system performance. By supporting common PC
peripheral interface frequencies including 25 MHz for
Ethernet and 24.576 MHz for audio and other
applications, the device lowers chip count enhancing
system cost and reliability.
The ICS411 utilizes a low pin count 8-pin SOIC
package to optimize board space.
ICS is a leader in low jitter and power consumer
application clock sources. These devices are capable
of supporting CCD, video, audio, USB, CPU, and other
peripherals.
