ICS9120-11
Frequency Generator for Multimedia Audio Synthesis
General Description
The ICS9120-11 is a high performance frequency generator.
The ICS9120-11 provides high accuracy; low jitter PLLs
meet the 0.20% frequency tolerance and -96dB signal-to-
noise ratios. Fast output clock edge rates minimize board
induced jitter.
The ICS9120-11 operates over the entire 3.0 - 5.5V range
and provides power-down to minimize energy consumption.
Features
• Generates 46.6 MHz and 33.868 MHz clocks
• Buffered REFCLK output
• 0.20% frequency accuracy
• 100ps one sigma jitter maintains 16-bit performance
• Output rise/fall times less than 2.5ns
• On-chip loop filter components
• 3.0V - 5.5V supply range
• 8-pin, 150-mil SOIC package Advance Information

Note: PD# (Pin 8) and OE (Pin 4) are internally pulled-up
to VDD and therefore may be left disconnected or driven by
open collector logic.
