Multi-Rate SDI Adaptive Cable Equalizer
Description
The GS1524 is a second-generation high-speed bipolar integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable at data rates from 143Mb/s up to 1.485Gb/s. The GS1524 is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s.
KEY 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
• 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)
• Pb-free and RoHS Compliant
• cable length indicator for SMPTE 259M inputs
• output mute based on max cable length adjust or manual override
• 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
