ICS9120-48
Frequency Generator for CD-ROM Systems
General Description
The ICS9120-48 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 ICS9120-48 operates over
the entire 3.0-5.5V range.
Features
• Generates the output clock frequencies required by
CD-ROM drive systems
• Single 16.9344 MHz crystal or system clock reference
• 100ps one sigma jitter
• Output rise/fall times less than 2.0ns (at 5V VDD)
• On-chip loop filter components
• 3.0V-5.5V supply range
• 150 ppm output frequency accuracy
• 8-pin, 150-mil SOIC
Applications
• Specifically designed to support CD-ROM drive
requirements of multimedia applications
