Cyclone V: Dynamic phase shift

I am implementing this using the PLL Intel FPGA Megafunction (ALTERA_PLL) Is this the best IP to use where I wish to adjust phase relationships? I can't find any documentation to suggest the phase ...

Thanks for the reply.

Although the input and output frequencies are both 50MHz, I can see under "Advanced Parameters" the "PLL Output VCO Frequency" is "300.0 MHz".

So I assume from that there should be 48 steps.

Hi,
you find the phase step information for all PLL outputs in compilation report/fitter/resource section/PLL usage

    Many thanks, I can confirm the PLL Usage Summary does say the PLL VCO Frequency is 300MHz.
