external CMOS clock of AD7134

Category: Hardware

In my circuit, the clkvdd is connected to the 1.8V power supply.The circuit diagram is as follows:

Measure the voltage of XTAL2 with an oscilloscope as follows:

The maximum voltage of the input sine wave is 2.34V and the minimum voltage is -0.4V. Does the external input clock meet the requirements under this circuit?
