The AD807 acquires frequency and phase lock on input data using two control loops that work without requiring external control. The frequency acquisition control loop initially acquires the frequency of the input data, acquiring frequency lock on random or scrambled data without the need for a preamble. At frequency lock, the frequency error is zero and the frequency detector has no further effect. The phase acquisition control loop then works to ensure that the output phase tracks the input phase. A patented phase detector has virtually eliminated pattern jitter throughout the AD807. The device VCO uses a ring oscillator architecture and patented low noise design techniques. Jitter is 2.0 degrees rms. This low jitter results from using a fully differential signal architecture, Power Supply Rejection Ratio circuitry and a dielectrically isolated process that provides immunity from extraneous signals on the IC. The device can withstand hundreds of millivolts of power supply noise without an effect on jitter performance.
