Instructions:
Enter a value in the Loop Bandwidth input box (default is 10).
Enter a value in the VCO Gain input box (default is 124.416).
Select a value from the Phase Detector drop-down box (default is 20).
Select a value from the Predivider drop-down box (default is 8).
Select a value from the Gain Logic Divider drop-down box (default is 1).
Enter a value in the R3 input box (default is 332).
Press the calculate button to compute your results.
* R3 should not exceed 1kΩ because of the op-amps inability to drive large loads.
** C2 is only nescessary if R1 is over 500kΩ. It will filter noise from the charge pump and prevent clipping in the op amp.
*** The higher order pole is recommended to be 4*K to reduce pole interference.
**** The zero frequency is recommended to be 100 time less than K to reduce peaking in the transfer response.
