ICS409
PC PERIPHERAL CLOCK
Description
The ICS409 is a cost-effective clock synthesizer
developed to optimize component count for PC
peripheral applications. The device supports a
common, low cost 14.31818 MHz crystal using an
on-chip crystal oscillator. The device locks all output
frequencies to enhance system performance. By
supporting common PC peripheral interface
frequencies including dual 25 MHz and 40/80 MHz
frequencies the clock lowers chip count enhancing
system cost and reliability.
The ICS409 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.
Features
