ICS409

PC PERIPHERAL CLOCK

Description

Features

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.

• Pin compatible with FS6286-01

• Low operating voltage of 3.3V

• On-chip oscillator supports 14.31818 MHz crystal

• Fixed dual 25 MHz clocks for Ethernet

• 40/80 MHz selected on rising edge of OE/LAT pin

• Power consumption of 15 mA (typ)

• Duty cycle of 45 to 55%

• Packaged in 8-pin SOIC

• Available in Pb (lead) free package

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.
