Key Features
- 12.5 Gbps CoaXPress 2.0 compliant transceiver with integrated cable equalization for long-distance video transmission
- Supports both transmit and receive paths in a single 16-pin QFN package, reducing board space by up to 40%
- Adaptive equalization compensates for coaxial cable losses at distances up to 100 m at 12.5 Gbps
Applications
The EQCO125X40C1T-I/8EX is purpose-built for machine vision camera links using the CoaXPress 2.0 standard, enabling 12.5 Gbps full-duplex communication between industrial cameras and frame grabbers over a single coaxial cable. It is also deployed in broadcast video infrastructure and high-speed test systems where long cable runs must maintain signal integrity without active repeaters. Medical imaging and robotic vision platforms benefit from its compact package and low-power equalization design.

Frequently Asked Questions
At what maximum data rate does the EQCO125X40C1T-I/8EX operate under CoaXPress 2.0?
The EQCO125X40C1T-I/8EX supports a maximum data rate of 12.5 Gbps per lane, compliant with the CoaXPress 2.0 standard. This allows transmission of high-resolution video frames over a single 75 Ω coaxial cable in industrial machine vision systems.
Which package does this Microchip equalizer IC use, and how many pins does it have?
The EQCO125X40C1T-I/8EX is housed in a 16-pin QFN (quad flat no-lead) package. The compact footprint of approximately 3 mm × 3 mm makes it suitable for space-constrained PCB designs in camera modules and embedded video processing boards.
How does the EQCO125X40C1T-I/8EX compensate for signal loss over long coaxial cable runs?
The IC incorporates adaptive continuous-time linear equalization (CTLE) that automatically compensates for frequency-dependent insertion loss in coaxial cables. At 12.5 Gbps, it can maintain a clean eye opening for cable lengths reaching 40 m or more depending on cable quality, removing the need for manual calibration in production.
When would a system designer choose EQCO125X40C1T-I/8EX over a simpler 6.25 Gbps CoaXPress device?
A designer selects the 12.5 Gbps EQCO125X40C1T-I/8EX when the camera sensor outputs resolutions of 25 MP or higher at frame rates above 30 fps, requiring the doubled bandwidth of CoaXPress 2.0 CXP-12 links. At lower resolutions below 5 MP at 60 fps, a 6.25 Gbps CXP-6 device suffices and reduces power consumption by roughly 30%.
