ABSTRACT:
A constant loop gain phase lock loop for recovering a clock from non-uniformly spaced data pulses utilizes a programmable current source and charge pump whereby the current into the charge pump is proportional to the number of VCO clock periods between data pulses. As the time between pulses increases the current charging the pump increases and when the time between pulses decreases the current charging the pump decreases to maintain a constant loop gain independent of the data pattern.
