Abstract

PURPOSE:To pick up a timing signal from binary or ternary code, by obtaining an output signal of the 1st and 2nd level shift circuits which can change level shift amount and providing the 1st and 2nd differential amplifiers making slice of input waveform through the output signal of the level shift circuits. CONSTITUTION:Differential output signals (a), (b) of an equalizing amplifier circuit are as shown (A) for binary code and as shown (B) for ternary code. A binary/ternary control terminal 18 is grounded for binary code and opened for ternary code. Then, the level shift amount at level shift circuits 11, 12 can be changed. At a binary code, only a differential amplifier 13 is operated and no differential amplifier 14 is operative. Signals c-f respectively level-shfted at the circuits 11, 12 are given to the differential amplifiers 13, 14 and at binary code a signal (g) shown in (C) is outputted from an output terminal 19 and at ternary code, the signal (g) shown in (D) is outputted.
