A parallel to serial conversion circuit is disclosed. The circuit is used for converting parallel bits representing a plurality of words into serial bits. The circuit consists of storing means which comprises a plurality of word locations for temporarily storing the plurality of words at a parallel clock rate, and serialization means connected to the storing means for converting the parallel bits into serial bits at a serial clock rate. Each of the plurality of word locations is organized as a plurality of cells for storing each, one bit. Moreover the serialization means comprises parallel pointing means connected to the storing means for pointing to the plurality of words locations synchronously to the parallel clock, and serial pointing means also connected to the storing means for pointing to the plurality of cells synchronously to the serial clock. Filling indicator means are connected both to the parallel pointing means and to the serial pointing means for generating a status signal indicating the status empty or full of the storing means such that the serial pointing means is responsive to the status signal for successively pointing to the plurality of cells when the status is full.
