Title:
SIMULTANEOUS TWO-WAY TRANSMISSION RECEPTION METHOD AND SIMULTANEOUS TWO-WAY TRANSMISSION RECEPTION CIRCUIT
Document Type and Number:
Japanese Patent JPH1168861
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To attain simultaneous two-way transmission reception through one transmission line where transparent performance is warranted and data are sent accurately at a high speed. SOLUTION: Parallel data TPD are converted into serial data TSD0 by a parallel-serial conversion circuit 1a. The serial data are not warranted for DC balance on a transmission line. The serial data are converted into serial data TSD1 warranting a DC balance on a transmission line with a coding circuit 1c such as data by a Manchester code and the data are sent to a transmission line 1e via a data transmission reception circuit 1d. The data transmission reception circuit 1d extracts only a reception signal RSD1 from the signal on the transmission line 1e and a composite circuit 1f obtains the original serial data RSD0 and extracts a synchronizing signal CLK3 and the obtained serial data are converted into parallel data RPD by a serial-parallel conversion circuit 1g.
