GTL (Gunning Transceiver Logic)
GTL_DCI Usage
The Gunning Transceiver Logic (GTL) standard is a high-speed bus standard (JESD8.3)
invented by Xerox. Xilinx has implemented the terminated variation for this standard. This
standard requires a differential amplifier input buffer and an open-drain output buffer.
The negative terminal of the differential input buffer is referenced to the V

termination and unconnected V

GTL does not require a V
1.2V. GTL_DCI provides single termination to V
A sample circuit illustrating a valid termination technique for GTL_DCI with internal
parallel driver and receiver termination is shown in
