1. Gunning Transceiver Logic 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.
