MK1422 OPL3/4+Codec Portable Clock Source

The MK1422 is the ideal way to generate clocks for sound in portable computers. It provides clocks for Analog Devices’ or Crystal Semiconductor’s stereo codecs, and Yamaha’s OPL3L, OPL3LS, and OPL4. The MK1422 uses either a 14.318 MHz crystal, or a 14.318 MHz bus clock input to synthesize the clocks.
