Frequency Generator for Multimedia Audio Synthesis
Features
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.
