Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

The ICS9120-46 is a high performance frequency generator designed to support the clock requirements of communication and audio interfaces. It offers the clock frequencies required by 28.8 baud modem plus sound system. These frequencies are synthesized from 14.7456 MHz reference oscillator whose buffered output is available for the reference.

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 of the ICS9120-46 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.
