Semtech | GS2984-INE3

The GS2984-INE3 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75 Ω coaxial cable.

The device is designed to support SMPTE 424M, SMPTE292M and SMPTE 259M, and is optimized for performance at 270 Mb/s, 1.485 Gb/s and 2.97 Gb/s.

Features:

• SMPTE 424M, SMPTE 292M and SMPTE 259M compliant
• Automatic cable equalization
• Multi-standard operation from 143Mb/s to 2.97Gb/s
• Performance optimized for 270Mb/s, 1.485Gb/s and 2.97Gb/s. Typical equalized length of Belden 1694A cable:
  • 140m at 2.97Gb/s
  • 200m at 1.485Gb/s
  • 400m at 270Mb/s
• Supports DVB-ASI at 270Mb/s
• Manual bypass (useful for low data rates with slow rise/fall times)
• Programmable carrier detect with squelch threshold adjustment
• Differential outputs support DC coupling to 3.3V and 2.5V CML logic
• 0/6 dB gain boost selection pin
• Standard EIA/JEDEC logic control and status signal levels
• Single 3.3V power supply operation
• 195 mW power consumption (typical)
• Wide operating temperature range of -40ºC to +85ºC
• Small footprint QFN package (4mm x 4mm)
  • Drop-in compatible with the GS2974
• Pb-free and RoHS compliant

Applications:

• SMPTE 424M, SMPTE 292M and SMPTE 259M coaxial cable serial digital interfaces
