Increasing clocking frequencies of integrated circuits are giving rise to very fast interfaces between ICs and printed circuit boards, which can often not be satisfied by the manufacturers standard design libraries.
Low-voltage differential drivers and receivers support transmission frequencies up to the Gigahertz range. Since differential signalling is very robust against electromagnetic interference, low-cost twisted pair wiring is adequate for low to medium distances.
For use in several design projects, a low-voltage differential transmitter and receiver have been implemented in a small test chip for characterization purposes. A selection of austrianmicrosystems standard library input and output buffers have been added fir comparison reasons
