PLL 565 CLOCK RECOVERY (bit sync.)

[vinodquilon]

I am using PLL for clock recovery (see attachment).

What are the design criterion s for R1,C1,R2, and C4 ?
R2 and C4 determines free-running frequency of PLL.

What would be the selection for c2, which determines capture range ?
Does there any restriction on VCC selection as it affects lock range ?

Here I am using XOR to ensure frequent data transitions. That is to avoid Consecutive
Identical Digit (CID).

I am using this circuit in wireless communication to recover clock from received data for
bit synchronization.

I think R1 & C1 should design to provide one bit delay time.
R2 & C4 (VCO reference clock) should be tuned to lock at transmitter data rate.
I am choosing C2= 10uF, VCC= 5V.
