Description
The GS7025 provides automatic cable equalization and high-performance clock and data recovery for serial digital signals. The GS7025 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 35dB of gain at 135MHz, which typically results in equalization of greater than 350m of high-quality cable at 270Mb/s.

Key Features
• SMPTE 259M-C compliant (270Mb/s)
• Automatic cable equalization (typically greater than 350m of high-quality cable)
• Serial data outputs muted and serial clock remains active when input data is lost
• Operation independent of SAV/EAV sync signals
• Signal strength indicator output
• Carrier detect with programmable threshold level
• Power savings mode (output serial clock disable)
• Large IJT, typically 0.56UI beyond loop bandwidth
• Robust lock detect

Applications
    Cable equalization plus clock and data recovery for all high speed serial digital interface applications involving SMPTE 259M-C.
