7.2.1 Crystal Input or External Clock (X1)
This input is one of two connections to a crystal or a single connection to an external
clock. A crystal or an external clock signal, at 3.6864 MHz, must be supplied when using
the baud rate generator. If a crystal is used, a capacitor of approximately 10 pF should be
connected from this signal to ground. If this input is not used, it must be connected to V
or GND. Refer to Section 10 Applications for an example of a clock driver circuit.
7.2.2 Crystal Output (X2)
This output is the additional connection to a crystal. If a crystal is used, a capacitor of
approximately 5 pF should be connected from this signal to ground. If an external TTL-
level clock is used on X1, the X2 output must be left open. Refer to Section 10
Applications for an example of a clock driver circuit.
