Page 1
... The W48C20 is a general-purpose device that features two phase-locked loops. Through the use of metal masks, the chip can be tailored to a wide variety of applications. The W48C20 has four clock outputs, each of which is maskable to a different frequency. Because the chip offers four outputs in eight pins suited to applications that require multiple frequencies and have space constraints ...

... External Components/Crystal Selection The W48C20 incorporates a crystal oscillator circuit designed to provide 50% duty cycle over a range of operating conditions, including the addition of external crystal load capacitors to pins X1 and X2. A parallel resonant 14.318-MHz, 12-pF load crystal is recommended. A series-resonant crystal or a parallel reso- nant crystal specifying a different load can be used, but either will result in frequencies which are slightly different from the ideal ( ...
