Appeal No. 96-3054
Application 08/134,147
a phase detector for detecting a phase difference
between an input signal and said reference signal through
multiple clock cycles, and for providing a first phase
detector output signal representative of a detected phase
difference less than a single cycle, and for providing a
second phase detector output signal representative of a
detected phase difference greater than a single cycle;
control means, receiving said first phase detector
output signal and said second phase detector output signal,
for providing a voltage controlled oscillator (VCO) control
signal controlled by said first phase detector output signal
and said second phase detector output signal;
a voltage controlled oscillator receiving said VCO
control signal and providing said oscillator output signal
which is applied to said phase detector as the input signal
thereof.
