SX2 Crystal Oscillator Input

Question: While using CY7C68001, if a 24MHz clock is already in the  system, can it  just  be routed directly to the XTALIN pin, and leave the XTALOUT pin unconnected?

 

Answer:

Yes, as long as it meets the XTALlN/CLOCK specifications of 24 MHz +/- 100ppm. Leave the XTALOUT pin unconnected.
