General Description
The ICS9120-45 is a high performance frequency generator designed to support the clock requirements of communication and audio interfaces.
High accuracy, low-jitter PLLs meet the -96dB signal-tonoise ratios required by 16-bit audio systems. Fast output clock edge rates minimize board induced jitter.
The on-chip XTAL oscillator accuracy is better than ±100ppm for an AT cut, 18pF load crystal with initial accuracy of ppm plus TC, aging and load variation of ±20ppm each assuming 33pF ±5% external load capacitors.
