(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). {GTL/BTL: A Low-Swing Solution for High-Speed Digital Logic (http://www.edtn.com/scribe/reference/appnotes/md003ecc.htm)}.
