Abstract

See full text

A device for doubling or dividing by 2 the flow rate of series bits comprising a succession of first one-bit registers (R4-R0) actuated at a frequency F; a second register (R) actuated at a frequency 2F; an input terminal (IN) connected to the input of the first (R4) of the first registers and, through a first gate (T5), to an internal line (L) connected to the input of the second register; first multiplexers (M4-M1) connected to the input of each second (R3) to last (R0) of the first registers for selecting either the output of the preceding register, or the internal line, or still the output of the second register; a second multiplexer (M), which selects either the output of the last (R0) of the first registers, or the output of the second register, or filling bits; second transfer gates (T4-T0) between the output of each first register and the internal line; and means for controlling the various gates and multiplexers.
