  • Patent number: 5325395
    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.
    Type: Grant
    Filed: March 31, 1992
    Date of Patent: June 28, 1994

  • Patent number: 5272722
    Abstract: A transceiver has a transmitter portion using serially coupled FETs coupled o 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.
