ABSTRACT:
A bit clock regenerating circuit comprising an edge detector made up of two flip-flops for detecting edges of a binary signal and a gating circuit, a counter receiving an edge detected pulse from the edge detector as a load signal for setting an initial value, counting clock pulses with a given frequency, and generating a bit clock according to the result of the counting, and a ROM in which multiple conversion tables are formed to supply an initial value for the counter according to an output value of the counter, and a conversion table for determining regeneration conditions is selected according to a switching signal.
