PC PERIPHERAL CLOCK
IDT™ / ICS™ 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.
IDT 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.

... The nominal impedance of the clock output is 20Ω . Decoupling Capacitor As with any high performance mixed-signal IC, the ICS409 must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01µF must be connected between VDD and the PCB ground plane. IDT™ / ICS™ PC PERIPHERAL CLOCK ...
