SM8703CV Clock Generator for DVD Players OVERVIEW The SM8703CV is a 27MHz master clock, 5-system output clock generator for DVD players. It has 2 built-in PLLs that, with the addition of a single crystal oscillator element, can generate 384fs, 512fs and 768fs clocks which are necessary for MPEG2 systems, plus independent xed-frequency 27MHz and 33.8688MHz output clocks. Each output has an output disable function, when the output is not used, to suppress unwanted radiation. Also, the normal output frequency ratio between each output is maintained so that the visual and audio signals remain synchronized. Supported sampling frequencies (fs) include 44.1 and 48kHz.
