Frequency Generator for CD-ROM Systems

General Description

The ICS9120-49 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.

High accuracy, low jitter PLLs meet the 150 ppm frequency

tolerance required by these systems. Fast output clock edge

rates minimize board induced jitter.

Unlike competitive devices, the ICS9120-49 operates over

the entire 3.0-5.5V range.
