New Contributor1GHz clocks with 33% duty cycle
I'm looking for an FPGA that can generate high frequency clock signals(1GHz or more) with 33% duty cycle. I tried using Cyclone V SOC for this using PLLs but at 1GHz, 33% duty cycle is not possible. ...

Frequent ContributorHi there
Looking at the PLL spec of Cyclone V, it doesn't seem to support up to 1GHz output freq.

Cyclone V does support programmable duty cycle. We have to do some configuration on the counter value to achieve that. There is explanation regarding the setup:

hv2220If the cyclone V does not support 1GHz output freq, is there any other FPGA kit that can support >1GHz output frequencies at 33% duty cycle?
