Frequency Generator for Digital Video Systems he
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.
