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 fixed-frequency 27MHz and 33.8688MHz output
clocks. Each output has an output disable function, when the output is not used, to suppress unwanted radia-
tion. 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.
