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 required to drive the codec, and the 33.868 MHz required for the FM or wavetable music synthesizer. It includes a power down pin to save power without using a FET. In an 8 pin SOIC, the MK1422 can save component count, board space, and cost over surface mount crystals, and increase reliability by eliminating three mechanical devices from the board. MicroClock offers many o
