I wants to make clock recovery PLL with external discrete devices.
How can I make 27Mhz VCO with discrete devicces?
Dividers will be implemented with altera FPGA chip.
And Philips's 74HCT9046 phase comparator is selected for PD.
Alaso 2nd oder low pass filter is selected for loop fiters.
But I couldn't design 27MHz VCO with discrete devices.
I am a logic design engineer.
I have no sufficient experience in VCO design.
Please let me solve this problem.
Thanks
