High-speed Networking and Video




ARCNET has many characteristics that make it ideal for industrial and embedded networking environments. This is due to the deterministic nature of ARCNET, its high reliability and fault tolerance, and its adaptability to a wide variety of cabling media and configurations. Microchip is the market leader in ARCNET devices and has a full spectrum of solutions to meet any customer’s price and performance needs.

CircLink, an ARCNET derivative, further improves on the protocol by eliminating the need for external processor and is optimized as a wire-replacement technology inside industrial and commercial machines.

CoaXPress is the new standard for high performance machine vision systems. CoaxPress is the state of the art method of connecting high performance machine vision cameras to Frame Grabbers or video servers.


CoaXPress operates over standard 75-ohm coax cable. It currently supports up to 6.25Gbit/s from the camera to the Frame Grabber. A lower bandwidth signal, up to 20Mbit/s for the control functions can be sent the other way over the same cable. Simultaneously, power is supplied over the coax – to power the camera. The CoaXPress standard allows for a number of cables to be used in parallel, for example, 4 cables offering 25Gbit/s image data streaming.

EqcoLogic’s CoaXPress transceivers – EQCO62R20 and EQCO62T20 support high performance CoaXPress links.

Ethernet Overview

Microchip’s Ethernet Portfolio


A wide range of remote communication features are possible when Ethernet connectivity is added to embedded designs. For example, it can enable end users to remotely monitor systems using a web browser or receive emails triggered by service alerts or low product inventory. It saves cost and time since they can centrally monitor, control and service their embedded systems over the internet instead of physically being there. Microchip’s Ethernet solutions are designed to support the growing needs of these markets with a full complement of robust, highly integrated Ethernet devices complemented by a full line of PIC32/SAM MCUs, and SAM MPU host processors.


Need to double your cable length up to 200 meters at full bandwidth? Try adding an Ethernet single-coax transceiver. Get started with the FastECoax7501.

Fiber Optic Module Chipsets

Fiber Optic Module Controllers


Microchip offers a family of fiber optic module controllers which enable the implementation of sophisticated, hot-pluggable fiber optic transceivers with intelligent laser control and an internally calibrated digital diagnostic monitoring interface per SFF-8472. They essentially integrate all non-datapath functions of an SFP transceiver into a small package (3 x 3 mm or 4 x 4 mm). These controllers also work well as a microcontroller peripheral in transponders or 10 Gbps transceivers.


A highly configurable Automatic Power Control (APC) circuit controls laser bias. Bias and modulation are temperature compensated using dual DACs, an on-chip temperature sensor and NVRAM look-up tables. A programmable internal feedback resistor provides a wide dynamic range for the APC and power monitoring. Controlled laser safety features and turn-on facilitates hot plugging. The I2C- SMBus-compliant serial interface allows for the communication with the host MCU. The MIC3003 controller works over an extended temperature range.



  • Integrates all FOM modules, no data path functions
  • SFF-8472 MSA compliant
  • Easy module parameters settings, no programming required
  • Small package
  • Low power
