Abstract

Described herein is a feed forward equalizer that is configured to operate in a normal operational mode and in a test operational mode. The feed forward equalizer has an input port and an output port which are used for the normal operational mode. A test input port and a test output port are provided in the feed forward equalizer, and are used for the test operational mode. Buffers may be provided for matching the impedance of respective ones of the input, output, test input, and test output ports. The feed forward equalizer allows testing during development, and once mounted in an integrated circuit, without interfering with the normal operational mode.
