Designed to support HD-SDI and HDcctv camera systems, this EqcoLogic transceiver set is for video connections with speeds of up to 3.0 Gbps; features a transmitter with low speed receiver channel (camera end) and high speed receiver with low speed transmitter (recorder end). designed for 75ohm coaxial cable. Supports Power transmission over same coax cable.

The EQCO30T5 device is designed to drive the high speed video signals from the camera and to receive low speed control signals from the control unit or recorder. The EQCO30R5 is the receiver for high speed video (incorporating proprietary Equalizer technology)and the driver for the low speed control signals.

The device pair is used in products such as HD-SDI repeaters, system units to boost cable length.


This solution is useful and economical for many markets and applications, including the following:

  • High Definition, high frame rate Pro-video HD/SDI video transmission
  • Surveillance, industrial/inspection, medical video
  • Repeaters for long-haul transmission of HD-SDI signals

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%.
