Abstract
One embodiment relates to a receiver circuit for a data link. The receiver circuit includes a linear equalizer for receiving an input data signal and outputting an equalized signal, and a variable gain amplifier for receiving the equalized signal and outputting an amplified signal. Adaptation circuitry is connected to the linear equalizer and the variable gain amplifier. The adaptation circuitry adapts both a gain of the variable gain amplifier and a direct current voltage setting of the linear equalizer. Other embodiments and features are also disclosed.
