Product Description
The CY24233 is a clock generator solution that supports DVD
digital disk players. It produces a complete set of clocks
needed to support the entire system. All output clocks are
synthesized from a single 27.00-MHz fundamental cut crystal
or input reference clock. The output clocks are precisely
synthesized to meet the systems low PPM error requirements.
