The clock multiplier unit (CMU) PLL VCO frequency range

Hie Andrei, As you are aware our datasheet spec list the supported frequency range for every PLL instead of VCO frequency. Currently, we do not have a customer facing document covering the VCO and PFD frequency range for every PLL. This is because not all combinations of refclk frequency ,VCO frequency , L, M and N counter is supported. This values were characterized and supported values were included as part of Quartus. One way you can determine this is by using Quartus tool. Use the Transceiver ATX PLL, fPLL or CMU PLL Intel Arria 10 FPGA IP. Key in the min/max refclk frequency and required frequency numbers. You can observed the VCO frequency in the Advanced Parameters tab Regards, Nathan
