The XTAL1 input can accept single ended LVCMOS signal
through an AC couple capacitor. A general interface diagram
is shown in Figure 4. The XTAL2 input can be left floating. The
edge rate can be as slow as 10ns. If the incoming signal has
sharp edge rate and the signal path is a long trace, proper
termination for the driver and controlled characteristic imped-

ance trace may be required. The input can function with half
swing amplitude. Reducing amplitude from full swing of 3.3V
to half swing of about 1.65V can prevent signal interfere with
power rail and may reduce noise. Please refer to the LVCMOS
driver data sheet and application note for amplitude reduction
and termination approach.
