Title: Differential transmission system
Inventor: HOJO MAKOTO
IPC: H04L25/02
Filed: 2001-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a differential transmission system that can ensure a differential input voltage of a master station receiver circuit. SOLUTION: In the differential transmission system of 1 to N connection, a stabilizing circuit 8 having a driver circuit 81 is connected to an incoming transmission line 6, a control line 7 is provided between slave stations 2A to 2C and the stabilizing circuit 8, each slave station outputs a signal to control a driver circuit 22 and inverted by an inverter 23 to the control line 7, and the signal resulting from inverting the signal of the control line 7 by an inverter 82 of the stabilizing circuit 8 drives the driver circuit 81 of the stabilizing circuit 8.  Since the driver circuit 81 of the stabilizing circuit 8 can drive the incoming transmission line 6 when the slave stations 2A to 2C do not drive the incoming transmission line 6, the differential input voltage of the master station receiver circuit 12 to which a termination resistor Rt2 is connected can be ensured when the slave stations 2A to 2C do not drive the incoming transmission line 6. Thus, a fail safe circuit having been adopted for a conventional differential transmission system is not required, limitation of a transmission rate and a transmission distance can be eliminated and since the impedance of the intermediate frequency transmission line 6 is reduced, the noise immunity can be enhanced.
