Abstract
A phase detector (1) for a phase locked loop (PLL) for bit clock retrieval where the phase detector employs a plurality of variable unit delays (20,21) and has a constant gain region that is a percentage of the clock period over an extended frequency range of the VCO enabling a single (PLL) chip to operate for several applications at widely different frequencies.
