Description
The GS1574 is a second-generation high-speed bipolar integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable.
The GS1574 is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s.
The GS1574 features DC restoration to compensate for the DC content of SMPTE pathological test patterns.

Features
• SMPTE 292M, SMPTE 344M and SMPTE 259M compliant
• Automatic cable equalization
• Multi-standard operation from 143Mb/s to 1.485Gb/s
• Supports DVB-ASI at 270Mb/s
• Small footprint (4mm x 4mm)
• Pb-free and RoHS Compliant
• Pin compatible with the GS9074 Cable Equalizer
• Manual bypass (useful for low data rates with slow rise/fall times)
• Performance optimized for 270Mb/s and 1.485Gb/s
• Typical maximum equalized length of Belden 1694A cable: 140m at 1.485Gb/s, 350m at 270Mb/s
• 50Ω differential output (with internal 50Ω pull-ups)
• Manual output mute or programmable mute based on max cable length adjust
• Single 3.3V power supply operation
• Operating temperature range: 0°C to +70°C

Applications
• SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial Cable Serial Digital Interfaces.
