GTL

abbreviationStandard termElectronics

A low-voltage signaling standard used for high-speed backplanes and processor buses.

GTL stands for Gunning transceiver logic. It is a logic signaling standard that uses a low voltage swing (typically 0.8V to 1.2V) to achieve high switching speeds with minimal electromagnetic interference. It requires a terminated transmission line and an open-drain driver, making it highly effective for multi-drop processor buses.

Heard on the job

The bus analyzer shows reflections on the GTL lines, so we need to verify the termination resistor values.
