Microchip Technology has unveiled new CoaXPress (CXP) devices that will streamline machine vision system design, maximize transmission speed and simplify deployment in high-volume bottling operations, food inspection, industrial inspection and imaging applications.

Microchip’s EQCO125X40 family of CoaXPress devices is the first to implement the CXP 2.0 standard - the 12.5Gbps CoaXPressÒ 2.0 interface standard was ratified last year - starting from a new backward compatible design based on the specification, with an integrated clock data recovery (CDR) at all speed levels and a camera-side clock to support the demands of real-world environments.

The devices have been designed to significantly increase machine-vision processing throughput by enabling cameras and capture cards to transmit four to eight times faster than alternative solutions. In addition, these devices enable four times the cable/link distance with much lower power and near-zero latency.

The product family increases design tolerances and flexibility by seamlessly locking on all frequencies at any speed, from CXP-1 to CXP-12, and eliminates the need for multiple channels by supporting 12.5Gbps of bandwidth over a single cable. Broader cabling options ensure systems can be installed where needed and the integrated CDR improves jitter performance for the signal sent from the camera to the capture card.

The on-camera low-frequency clock recovery eliminates the need to program a separate clock in the FPGA. The integrated link signal integrity testing enables the system to perform real-time checks of cable link integrity before and during operations.

“We have worked with the Japan Industrial Imaging Association (JIIA) standards organisation and our lead customers to optimise our offering in conjunction with CXP so it fully exploits the specification’s benefits on the factory floor,” said Matthias Kaestner, vice president, Automotive Infotainment Systems business unit. “Our low-latency, low-power transmission solutions integrate an equalizer, cable driver and clock data recovery into a single chip that enables camera and capture card manufacturers to deliver high-speed, high-resolution video and control signalling along with power over a single coax cable.”

Microchip’s CXP devices enable manufacturers to get the same throughput from two ports on cameras and frame grabbers as they previously could with four. The devices can be used to retrieve a real-time low-frequency clock at the camera side, which provides more accurate signal timing. The manufacturers can also use it as a cable repeater, further extending the distances over which the cameras can be linked. Their low power consumption makes them ideal for bringing to market smaller, better-performing image-capture solutions that increase customer value yet are simpler and less costly to design.

While the company expects that its CoaXPress 2.0 family will have a significant impact on manufacturers, it believes that these devices will also have an equally transformational effect on applications including traffic monitoring, surveillance and security, medical inspection systems and embedded vision solutions.

The family is part of an extensive product portfolio spanning the requirements for creating total system solutions, including Microchip’s 12Gbps PolarFire field programmable gate arrays (FPGAs) that support the CoaXPress protocol with minimal developer effort while enabling a low-power, low-latency and small-footprint solution.
