The GS9025A provides automatic cable equalization and high performance clock and data recovery for serial digital signals. The GS9025A receives either single-ended or differential serial digital data and outputs differential clock and retimed data signals at PECL levels (800mV). The onboard cable equalizer provides up to 40dB of gain at 200MHz which typically results in equalization of greater than 350m of high quality cable at 270Mb/s.
