External Crystal.
If a 25 or 27 MHz crystal is used as the device frequency reference, connect it across
XA and XB. If no input clock is used, this pin should be tied to GND.

This pin is the least significant bit of the Si5356 I
devices to occupy the same I
Single-Ended Input Clock.
If a single-ended clock is used as the device frequency reference, connect it to this pin.
This pin functions as a high-impedance input for CMOS clock signals. The input should
be dc coupled. If a crystal is used as the device frequency reference, this pin should be
tied to GND.
