NRZ DATA-BIT SYNCHRONIZING DEVICE

PURPOSE: To stably restore NRZ data and clocks. CONSTITUTION: Even when not only PLL loop gain does not sensitively change, corresponding to a bit pattern and a bit speed of inputted NRZ data but also the NRZ data are not shifted and the range of the clock frequency change of a voltage-controlled os...

description PURPOSE: To stably restore NRZ data and clocks. CONSTITUTION: Even when not only PLL loop gain does not sensitively change, corresponding to a bit pattern and a bit speed of inputted NRZ data but also the NRZ data are not shifted and the range of the clock frequency change of a voltage-controlled oscillator 27 is large, the voltage-controlled oscillator 27 is made to oscillate so as to be synchronized with the multiple of the frequency of an external reference clock pulse REFCP. Thus, an NRZ data bit synchronization device for stably restoring the NRZ data and the clocks is obtained.
