A diskette read data recovery system generates a clock which is locked to an incoming data stream. In a phase locked loop, a signal generated by an oscillator and frequency dividers is compared in phase to the incoming data stream to provide first or second signals depending on whether the incoming data signal leads or lags the clock signal. In order that the system may handle different types of incoming signals, different frequency divider circuits in the phase locked loop are selected for different incoming signals.
