The ICS9118-03 a nd ICS9118-04 a re low-cost, highperform-ance clock generators designed to support digital video systems. 1.8MHz UART and AUDIO clocks are generated from the recovered 27MHz reference signal. The -03 supports 256x audio oversampling, and the -04 supports 384x audio oversampling. The audio clock is synthesized from 27 MHz using a high accuracy, low jitter PLL to meet the synchronization and -96dB signal-to-noise ratios required by 16-bit DSP systems. Fast output clock edge rates minimize board-induced jitter.
