1GHz clocks with 33% duty cycle

[hv2220]

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. 

Please let me know if there is a better FPGA solution(preferably and eval board).  The main issue is that most FPGAs do support 1GHz clock frequencies but they all are at 50% duty cycles. Getting variable duty cycles is hard. 

Secondly, I will need 3 such clock signal outputs with each having a variable phase shift.

Hi 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:

If 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?
