8 C counters range from 1 through 512 if the output clock uses a 50% duty cycle. For any output clocks using a non-50% duty cycle, the post-scale counters range from 1 through 256.
9 Only applicable if the input clock jitter is in the input jitter tolerance specifications.
10 The smallest phase shift is determined by the VCO period divided by eight. For degree increments, the Intel® Cyclone® 10 LP devices can shift all output frequencies in increments of at least 45°. Smaller degree increments are possible depending on the frequency and divide parameters.
