Clock Generators, PLLs, Frequency Synthesizers FAQ

How many times can the CY23FP12 be reprogrammed?

The device is based on flash technology and can be reprogrammed up to 100 times.

What is the typical output-to-output skew for this device?

The typical output-to-output skew is 35 ps when all outputs are at the same frequency.

Can the device operate without the PLL enabled?

Yes, the device can be configured as a non-PLL fanout buffer by shutting down the PLL, allowing the reference clock to pass directly to the outputs.
