Title: Timing clock generating circuit of recovery repeater
Inventor: SHIBATA MAKOTO
IPC: H04B3/36
Filed: 1985-05-10
Abstract: PURPOSE:To generate a waveform without phase deviation as a timing clock generating circuit by synchronizing an inputted reference frequency with an oscillating frequency in a phase locked loop. CONSTITUTION:When a variable voltage is lower than a reference voltage and the phase is retarded, an output of a phase comparator 251 goes to a low level during this period. A low level pulse is integrated by a low pass filter 252 and gets higher than the preceding level. That is, since the filter 252 employs negative feedback, when the input voltage is lowered, the output voltage rises. As a result, the voltage controlled oscillator 253 oscillates a higher frequency than the preceding frequency. The process above is repeated, and phase locking is taken, a timing clock without jitter obtained by the oscillator 253 is inputted to a discrimination circuit, an equivalent data waveform is identified and sent to the transmission lines as a new recovery waveform by a data recovery section.
