3.13 External Clock Oscillator
A 20-MHz quartz crystal or CMOS clock input
is required by the CS8900A. If a CMOS clock
input is used, it should be connected the to
XTAL1 pin, with the XTAL2 pin left open. The
40
CIRRUS LOGIC PRODUCT DATASHEET
clock signal should be 20 MHz ±0.01% with a
duty cycle between 40% and 60%. The speci-
fications for the crystal are described in
Section 7.7 on page 122.
