K142 Overview
The MK1422 is the ideal way to generate clocks for sound in portable puters. 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 required to drive the codec, and the 33.868 MHz required for the FM or wavetable music synthesizer.
