- You will find a short overview of GTL in the 1992 ISSCC p 58..."A CMOS Low-
- Swing Transmission-line Transceiver". Bill Gunning is one of the authors.
- No other direct reference is made, but databooks by LSI and National are
- cited. I have found GTL atractive when you must drive a multi-tapped
- bidirectional bus and only have a CMOS process. You may find better solutions
- for other topologies and technologies. With the newer 3.3V processes, even
- a NMOS-NMOS push-pull output can be faster and modest in its power requirements.
- The larger ~2.5V swing of this push-pull means that you will not need a
- differential receiver or voltage reference.
