Abstract

A simplified phase-locked loop (PLL) is provided by an improved phase discriminator which compares the phase of the incoming data stream with that of a voltage-controlled oscillator (VCO). This system uses a new phase discriminator and data sampling scheme. The charge pump, filter, and VCO are conventional.
