High-Speed Networking and Video


High-Speed Communications

Microchip has a large portfolio of high-speed communication ICs for different fiber optic applications with data rates ranging from sub-Mbps up to 12.5 Gbps. For point-to-point continuous-mode applications, a wide choice of limiting amplifiers, laser drivers and VCSEL drivers is offered to cover all kind of applications such as GbE/10GbE, Sonet/SDH and Fibre Channel. For point-to-multipoint PON applications, Microchip offers the burst mode limiting amplifiers family with industry-leading performance for GEPON/GPON, 10GEPON, XGPON and NG-PON2 applications. A family of SFF-8472 MSA fiber optic module management ICs completes the chipset offering. The high-speed communications products also include a family of Clock and Data Recovery (CDR) ICs  for operations up to 2.7 Gbps.

Limiting Amplifiers

Microchip's limiting amplifiers detect tiny differential or single-ended data signals from the receiver and boost them to full CML or LVPECL output levels to allow for the signal to overcome the losses and degradations it may encounter in its path to the SerDes or CDR on the line card.

All the limiting amplifiers feature loss of signal and/or signal detect circuit. Microchip's portfolio covers a wide range of applications in fiber optic transceivers for data rates as low as sub-Mbps to 12.5 Gbps.


  • Solutions for all fiber optic application up to12.5 Gbps
  • Industry-leading performance for PON applications
  • Work down to DC, no lower cutoff frequency
  • Fastest signal loss/detect response time
  • Low power and small package

Laser Diode Drivers

Microchip offers a family of edge emitting (DFP/FP) lasers and surface emitting (VCSEL) drivers that cover applications such as GbE/10GbE, Sonet/SDH and Fibre Channel for data rates ranging from sub-Mbps to 10 Gbps. The drivers are designed to work with Microchip's SFF-8472 compliant FOM modules controller, MIC3003. With the limiting amplifier, Microchip's chipset solution presents an elegant, smart, low-power, small-footprint solution for SFF/SFP/SFP+ modules.


  • Application up to 10 Gbps
  • Edge emitting and surface emitting lasers
  • Low power
  • Small package


Microchip offers a transceiver that includes a laser driver and limiting amplifier integrated into a small package. Combined with Microchip's SFF-8472 compliant FOM modules controller, MIC3003, it presents an elegant, smart, low-power, small-footprint solution for SFF/SFP modules with both edge emitting (DFP/FP) lasers and surface emitting (VCSEL).


  • Integrated laser driver and limiting amplifier
  • Works with the MIC3003 controlle
  • For applications with edge-emitting or surface-emitting lasers up to 4.25 Gbps
  • Small package

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

Clock and Data Recovery 

Microchip offers a family of Clock and Data Recovery (CDR) ICs for high-speed data signal cleaning and retiming in applications such as SONET, Gigabit Ethernet, Fiber Channel, and Infiniband with data rates ranging from 28 Mbps to 2.7 Gbps.


  • Wide range of applications up to 2.7 Gbps
  • SONET/SDH/ATM, Gigabit Ethernet, Fibre Channel, Infiniband applications
  • Complies with Bellcore, ITU/CCITT and ANSI specifications


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® Technology

CoaXPress® technology is a standard for high-performance machine vision, industrial inspection and traffic monitoring systems. CoaXPress is the state-of-the-art method for connecting high-performance, high-resolution cameras to high-speed capture cards (i.e. frame grabbers).

CoaXPress operates over standard 75-ohm, 50-ohm and shielded differential pair cables. CoaXPress Version 1.1 currently supports up to 6.25 Gbit/s per cable from the camera to the frame grabber. For the trigger and control function up to 20 Mbit/s can be sent simultaneously in the opposite direction via the same cable. Power is also supplied over the cable from the frame grabber to the camera. Furthermore, the CoaXPress standard allows for a number of cables to be used in parallel; for example, four cables offering up to 25 Gbit/s image data streaming with CoaXPress 1.1.

CoaXPress is the only open and royalty free standard that allows video, camera control and triggering, and up to 13W of power to be delivered via a single, off-the-shelf 75Ω coaxial cable up to 100m with standard BNC, Micro BNC or DIN1.0/2.3 connectors.

CoaXPress is also supported by GenICam, an Application Programming Interface standardized by European Machine Vision Association (EMVA) and has been widely adopted by many industry partners. It accelerates and simplifies application development as well as upgrading components of visions systems.

Robust, reliable, high-speed connectivity and control is possible when Ethernet networking is added to embedded designs. Ethernet enables systems to be monitored securely over the internet, allows for precision control of industrial motors at production facilities and enables new IoT products with common MCU interfaces like SPI, USB and 8-/16-bit parallel bus. Microchip's Ethernet solutions include highly integrated Ethernet PHYs, Bridges, Controllers and Switches complemented by a full line of PIC®32 MCUs, SAM ARM® MCUs, and SAM ARM MPUs.
