Gunning Transceiver Logic
GTL

   <electronics, hardware, integrated circuit, standard> (GTL) A
   {standard} for electrical signals in {CMOS} circuits used to
   provide higher data transfer speeds with smaller voltage
   swings [compared with what?].

   The GTL signal swings between 0.4 volts and 1.2 volts with a
   reference voltage of about 0.8 volts.  Only a small deviation
   of 0.4 volts (or thereabouts) from the reference voltage is
   required to switch between on and off states.  Therefore, a
   GTL signal is said to be a low voltage swing logic signal.

   Gunning Transceiver Logic has several advantages.  The
   {resistive termination} of a GTL signal provides a clean
   signalling environment [what?].  Moreover, the low terminating
   voltage of 1.2 volts results in reduced voltage drops across
   the resistive elements.  GTL has low power dissipation and can
   operate at high frequency and causes less {electromagnetic
   interference} (EMI).
