The MK1418 and MK1420 are the ideal way to generate clocks for new sound cards. The MK1420 provides clocks for Analog Devices’ AD1848, Crystal Semiconductor’s CS4231, and Yamaha’s OPL3L, OPL3LS, and OPL4. The MK1420 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 requi.
• Packaged in 8 pin SOIC
• Input crystal or clock frequency of 14.318 MHz
• MK1418 is clock input only
• MK1420 output clock frequencies of 16.934MHz, 24.576 MHz, 33.868 MHz, and 14.318 MHz
• Advanced, low power CMOS process
• Lowest jitter in industry for best audio performance
• Insensitive to input clock duty cycle
• 50% (typ) 14.318 MHz duty cycle with crystal AC Coupling/Portable Applications For applications in portable computers, it is possible to drive the input clock with a 3.3V, 14.318MHz clock by a.c. coupling using a 0.01µF capacitor connected in series to the CLKIN pin. But the op.
