6G SDI equalizer

The GS6140 is a high-speed BiCMOS device designed to equalize and restore signals received over cable.


  • Multi-standard operation at rates between 1Mb/s and 5.94Gb/s
  • SMPTE ST 2081 (proposed), SMPTE ST 292 and SMPTE ST 259 compliant
  • AES10 (MADI) compatible
  • Industry leading cable reach, with automatic cable equalization for different lengths of cable
  • Performance optimized for 125Mb/s, 270Mb/s, 1.485Gb/s, 2.97Gb/s and 5.94Gb/s. Typical equalized length of Belden 1694A cable up to:
    • 100m at 5.94Gb/s
    • 200m at 2.97Gb/s
    • 300m at 1.485Gb/s
    • 550m at 270Mb/s
  • 1.8V core power supply
  • 83mW when DC-coupled at +1.2V
  • Ultra-low power mode for shorter cable reach applications
  • Upstream launch swing compensation from 250mVppd to 1000mVppd in 50mV steps (Default 800mVppd)
  • Auto/Manual bypass (useful for low data rates with slow rise/fall times)
  • Robust, noise-immune signal detection with squelch threshold adjustment
  • Auto/Manual control of SLEEP/MUTE/DISABLE OUTPUT modes
  • Data Rate detection and indication
    • <MADI, MADI, SD, HD, 3G, 6G differentiation
  • Digital cable length indication (CLI)
  • Differential output supports DC-coupling from
  • 1.0V to 2.5V CML logic and AC-coupling for other logic families
  • Programmable/Rate-dependent output de-emphasis level and delay
  • Host interface for status and control
  • 6kV HBM ESD protection on all pins
  • Wide operating temperature range of -40ºC to +85ºC
  • Small footprint QFN–COL package (16-pin, 4mm x 4mm)
  • Pb-free and RoHS compliant


  •  SMPTE ST 2081 (proposed), SMPTE ST 424, SMPTE ST 292, SMPTE ST 259 and AES10 coaxial cable serial digital interfaces
