X1 and X2 clock multiplier outputs of CY7B994V with no reference

Last Updated: 09/11/2011

What frequencies can be expected at the X1 and X2 clock multiplier outputs in CY7B994V Clock part in the absence of any reference clock?

In the absence of a reference clock, the PLL is expected to lock to the zero frequency input. It will therefore run at a frequency below the specified range for the device, but still in the MHz range. For example, if FS = Low, fNOM will probably be somewhere in the range of 1 MHz to 20 MHz. It may have much higher jitter than when it is operating normally.
