DESCRIPTION
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 on-board 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.

FEATURES
• SMPTE 259M compliant
• operational to 540Mb/s
• automatic cable equalization (typically greater than 350m of high quality cable at 270Mb/s)
• adjustment-free operation
• auto-rate selection (5 rates) with manual override
• single external VCO resistor for operation with five input data rates
• data rate indication output
• 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)

APPLICATIONS
    Cable equalization plus clock and data recovery for all high speed serial digital interface applications involving SMPTE 259M and other data standards.
