CoaXPress Transceivers Sell Sheet

Transceivers for CoaXPress® Camera Solutions
Summary
CoaXPress (CXP) is an asymmetric high-speed point-topoint serial communication standard for the transmission
of video and still images, scalable over single or multiple
coaxial cables.
This solution supports a high-speed downlink of up
to 6.25 Gbps per cable for video and images, plus a
lower speed, 20 Mbps, uplink for communications and
control. Video transmission, power and data (control) are
simultaneous over a single cable. Cable lengths of greater
than 100m may be achieved.
Microchip Transceiver Devices
The figure shows the integration of Microchip transceivers
in a typical camera/frame-grabber configuration. The
CoaXPress system uses the asymmetric (high-speed one
way, low-speed the other) transceivers to transmit image
data from the camera and control signals and trigger
information from the frame grabber to the camera, making
local power supplies unnecessary.
The product family supports a variety of data rates:
■ EQCO62T20: transmits ≤ 6.25 Gbps;
receives ≤ 20 Mbit/s
■ EQCO31T20: transmits ≤ 3.125 Gbps;
receives ≤ 20 Mbit/s
■ EQCO62R20: receives ≤ 6.25 Gbps;
transmits ≤ 20 Mbit/s
■ EQCO31R20: receives ≤ 3.125 Gbps;
transmits ≤ 20 Mbit/s

Multiple Cable Links
High-speed image transmission can be supported by
using multiple CoaXPress links in parallel. For example,
the fastest CoaxPress solutions today use four channels,
offering up to 25 Gbit/s downlink bandwidth.
Standarization
CoaXPress has been standarized by JIIA and has been
accepted as a world standard by the G3 group including
AIA and EMVA.
The original CoaXPress technology was developed by
EqcoLogic (now Microchip), together with other members
of the CoaXPress consortium, including Adimec and
Active Silicon.
