NOTES:

1. Some W/X/Y/Z bit combinations shown may select a CLKOUT or VCO frequency higher than spec. Refer to Sec-

tion 11 Electrical Characteristics for CLKOUT and VCO frequency limits.

2. Any change to W or Y results in a change in the VCO frequency - the VCO should be allowed to relock if necessary.
