General Description

The ICS9120-52 is a high performance frequency generator designed to support digital compact disk drive systems. It offers all clock frequencies required for the servo and decoder sections of these devices. These frequencies are synthesized from a single 16.9344 MHz on-chip oscillator.

Features

• Generates 33.8688 MHz or 42.83 MHz decode clocks plus the 20 and 40 MHz fixed clocks

• Single 8.4672 MHz crystal or system clock reference

• 200ps one sigma jitter maintains 16-bit performance

• Output rise/fall times less than 2.0ns

• On-chip loop filter components

• 3.3V-5V supply range

• 8-pin, 150-mil SOIC

Applications

• Specifically designed to support the high performance requirements of CD-ROM drive systems
