Abstract : A transceiver has a transmitter portion using serially coupled FETs coupled to low level positive and negative bias sources to enable a low power drain conversion of TTL input signals to low level serial data output signals for a coaxial data transmission cable and vice versa The transceiver also provides a constant 50 ohm impedance for the coaxial or triaxial transmission cable during active transmission periods, stand-by periods and power-off periods to provide an inexpensive method to transmit and receive 10 Megabit coded data via a coaxial or triaxial cable.
