ABSTRACT:
A transceiver has a transmitter portion using active comparators coupled to single low level positive bias source to enable low powered drain transmit and receive conversion of TTL input signals to LLS (low level serial) data output signals for a coaxial data transmission cable. The transceiver also provides a constant impedance for a coaxial or triaxial transmission cable during active transmission periods, standby periods and power-off periods to provide a cost effective method to transmit and receive data.
