integrated circuit systems, inc. general description features ics9118-03 ics9118-04 frequency generator for digital video systems 9118-03 9 11 8 - 04 revb 7/28/99 block diagram the ics9118-03 and ics9118-04 are low-cost, high- perform-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. ? 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 pin configuration 8-pin soic functionality vdd=3.0-5.5v, temp=0-70 fer )zhm( sf ]0:2[ oidua 30 )zhm( oidua 40 )zhm( trau )zhm( 00.7 20 0 0e tatsir te tatsir te tatsirt 00.7 21 0 00 0.61*65 20 0.61*48 30 268.1 00.7 20 1 05 0.22*65 25 0.22*48 30 268.1 00.7 21 1 00 0.42*65 20 0.42*48 30 268.1 00.7 20 0 10 0.23*65 20 0.23*48 30 268.1 00.7 21 0 10 1.44*65 20 1.44*48 30 268.1 00.7 20 1 10 0.84*65 20 0.84*48 30 268.1 00.7 21 1 1w o lw o lw ol ics reserves the right to make changes in the device data identified in this publication without further notice. ics advises its customers to obtain the latest version of all device data to verify that any information being relied upon by the customer is current and accurate. obsolete ics9118-04 obsolete
