DEVICE FOR SERIALIZING HIGH FLOW OF BINARY DATA

摘要

PROBLEM TO BE SOLVED: To surely serialize data by providing a shift register, which gives a prescribed delay to parallel data, upstream a multiplexer. ;SOLUTION: Differential registers 12 and 14 constituting a shift register 16 of a serializing device 11 give a delay corresponding to a phase shift, which is generated between a first clock signal CLK0 and a first sampling signal CLK1, to parallel data DATAP outputted from a first level converter 5. Since data to be serialized is shifted by the delay based on the phase shift between the transmission frequency of serial data and that of input parallel data before multiplexing in a first multiplexer MUX1 in this manner, data is surely serialized even if a phase locked loop 2 is unlocked before data transmission.;COPYRIGHT: (C)1996,JPO
