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?



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