Abstract
A phase locked loop system is described for synchronizaing a clock signal to an incoming digital signal and simultaneously detecting that digital signal. The loop is capable of unaided frequency acquisition, hence eliminating the need for special circuits to 'pull' the loop into lock when the incoming data rate differs from the initial frequency of the VCO.
