General Description
The ICS9118-03 and ICS9118-04 are 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.

FEATUREs
• Genreates AUDIO codec and UART clocks synchronized to the 27MHz recovered video clock
• Selectable AUDIO clock supports 256x and 384x over-sampling of 16.00, 22.05, 24.00, 32.00, 44.10 and 48.00 kHz
• 80ps one sigma jitter maintains 16 bit performance
• Output rise/fall times less than 1.5nS
• On chip loop filter components
• 3.0V - 5.5V supply range
• 8-pin, 150-mil SOIC package

APPLICATIONs
• Specifically designed to support the high performance clocking requirements of digital video set-top and multi-media systems
