How to use external clock instead of resonator for XIN pin?

Latest Updated:03/20/2017

Question:

I wish to use an external clock instead of a resonator for clock supply to the XIN pin, and would like to know about the AC characteristics of the clock.

Answer:

The AC characteristics of an external clock that is supplied to the XIN pin are shown below.

Conditions
VCCE = 5 V +/-0.5 V, or VCCE = 3.3 V +/-0.3 V
VCCI = FVCC = VDD = OSC-VCC = 3.3 V +/-0.3 V
Ta = -40 degree C to 125 degree C

Note 1: Leave the XOUT pin open and make sure the parasitic capacitance is 10 pF or less
Note 2: To allow for the necessary PLL stabilization time, hold the RESET# input low for 10 ms or more after the clock oscillation has stabilized.
