| Integrated Circuit Systems, Inc. Frequency e h Generator for Digital Video Systems 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. e 4U t .c om Obsolete ICS9118-03 ICS9118-04 w w w .D a aS t 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 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.
