Description

The GS6042 is a high-speed BiCMOS device designed to equalize and restore signals received over 75 Ohms coaxial cable.
The device is designed to support 6G UHD-SDI, SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259, and is optimized for performance at 270Mb/s, 1.485Gb/s, 2.97Gb/s, and 5.94Gb/s.

Features


  • Multi-standard operation from 125Mb/s to 5.94Gb/s
  • SMPTE ST 2081, ST 424, ST 292, and ST 259-C compliant
  • Automatic cable equalization
  • Performance optimized for 270Mb/s, 1.485Gb/s, 2.97Gb/s, and 5.94Gb/s. Typical equalized length of Belden 1694A cable up to:
    • 80m at 5.94Gb/s
    • 210m at 2.97Gb/s
    • 300m at 1.485Gb/s
    • 550m at 270Mb/s
  • Supports DVB-ASI at 270Mb/s
  • Supports MADI at 125Mb/s
  • Manual bypass (useful for low data rates with slow rise/fall times)
  • Programmable carrier detect with squelch threshold adjustment
  • Automatic power-down on loss of signal
    • Standby power <35mW (typical)
  • Differential output supports DC-coupling from +1.2V to +3.3V CML logic
  • Option to compensate for 6dB flat attenuation prior to input of device
  • Selectable output de-emphasis: 2dB, 4dB and 6dB
  • Standard EIA/JEDEC logic control and status signal levels
  • Single +3.3V power supply operation
  • 180mW power consumption (typical)
  • Wide operating temperature range of -40ºC to +85ºC
  • Small footprint QFN package (4mm x 4mm)
    • Footprint compatible with the GS2974A, GS2974B, GS2984, GS2994, and GS3440
  • Pb-free and RoHS compliant
