Abstract

A packaged integrated circuit device includes a first driver, which has a first pair of differential output terminals and a first common-mode sensing terminal, and a second driver, which has a second pair of differential output terminals and a second common-mode sensing terminal. The second driver can be a smaller scaled replica of the first driver. A comparator and a reference signal generator are provided. The comparator is configured to compare first and second common-mode voltage signals developed at the first and second common-mode sensing terminals, respectively, and the reference signal generator is configured to provide the first and second drivers with a reference voltage having a magnitude that varies in response to changes in a signal generated at an output terminal of the comparator. This variation in the magnitude of the reference voltage supports a built-in adaptive response to changes in source-side termination in HCSL driver/receiver circuits.
