ICS9120-11 Integrated Circuit Systems, Inc. Frequency Generator for Multimedia Audio Synthesis General Description Features 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-tonoise 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.
