Frequency Error in CyberClocks for CY22393/4/5

Last Updated: December 13, 2013

Why do we get frequency error when we enter a value in the boxes for the PLLs in the advanced mode of the Cyberclocks for the CY22393, CY22394 and the CY22395 devices?


The range of the PLL's is 100-400 MHz for commercial temperature and 125-375 MHz for industrial temperature. Any frequency entered above or below this range would result in the error message, frequency error. In the Advanced Mode of the

CY22393 when you take the mouse pointer to the Desire (MHz) box of the PLLs, a window pops up which specifies the range of the PLLs.
