A quad (4 channel) equalizer designed for DisplayPort 1.2 and back-plane applications.


EQCO2754 supports extended cable lengths for 5.4 Gbps data-rates and is useful for many applications, including the following:

  • Support for Stereoscopic 3D full HD video
  • Driving of two 2560x1600 displays - e.g. Apple's 30-inch Cinema Display
  • Driving up to four 1920x1200 ( full HD ) displays on a single link via daisy chaining.
  • At 2.7 Gbps, the equalizer also extends the maximum cable length range significantly

The EQCO2754 can be used as an input device for all types of monitors, projectors etc. giving optimal compensation of frequency dependent signal loss.

The voltage regulator internal to the EQCO2754 allows easy integration into smart cables. Only a handful of supplementary low cost SMD capacitors are required to complete the function.

The EQCO2754 is a 4 channel equalizer. Each of the equalizers operate independently finding the optimal compensation level, deskewing the interpairskew by up to 40%.


Key Features

  • Long cable reach:
    • 15-20 m @ 2.7Gbps ( 25-30dB self adaptive compensation )
    • 10-15m @ 5.4 Gbps ( 30-35 dB self adaptive compensation )
  • Low current consumption ( 70mA/channel )
  • Internal input and output termination for low external component count
  • Single 1.2V or 3.3V supply ( internal linear regulator )
  • QFN package, pin count to be determined


Equalizer for video connections with speeds of up to 3.0 Gbps. The EQCO30R5 is designed to recover 3G-SDI signals after transmission over 75Ω coaxial cables; also supports data uplink for camera control and Power over Coax.
