PMC-Sierra is an American fabless semiconductor company which develops and sells devices into the communications, storage, printing, and embedded computing marketplaces.
Corporate history 
Pacific Microelectronics Centre (Burnaby, British Columbia, Canada) was spun off from Microtel Pacific Research (the research arm of BC TEL at the time) to develop ATM and later SONET chips. With investment from Sierra Semiconductor, PMC was established in 1992 as a private company focused on providing networking semiconductors, and became a wholly owned, independently operated subsidiary of Sierra Semiconductor in 1994. Microtel is currently a part of Verizon.
In August 1996, Sierra Semiconductor announced its decision to exit the personal computer modem chipset business, to restructure its other non-networking products and focus on its networking products. In 1997, the Company changed its name to PMC-Sierra to reflect the corporate focus on internetworking semiconductor solutions.
In May 2006, PMC-Sierra acquired Passave, Inc., a developer of system-on-chip semiconductor solutions for the Fiber to the home (FTTH) access market in a stock-for-stock transaction valued at approximately $300 million. Passave was headquartered in Boston, MA and had a development center in Tel Aviv, Israel.
Technology & Products 
PMC-Sierra provides broadband communications and storage semiconductors for metro, access, fiber to the home, wireless infrastructure, enterprise and channel storage, laser printers and customer premises equipment. PMC has more than 250 different semiconductor devices that are sold to equipment manufacturers, who in turn supply their equipment to communications network service providers and enterprises. PMC-Sierra is a “fabless” semiconductor company. The company designs and tests products, but outsources wafer fabrication and assembly functions to third party suppliers.
The company competes against established semiconductor companies that focus on the communications and storage semiconductor business. These companies include Agere Systems, Applied Micro Circuits Corporation, Broadcom, Exar Corporation, Conexant Systems, LSI Corporation, Marvell Technology Group, Mindspeed, Transwitch and Vitesse Semiconductor. Other competitors include major domestic and international semiconductor companies, such as Agilent, Freescale, Intel, IBM, Infineon, Motorola, NEC, Texas Instruments, and Toshiba.
Enterprise Storage 
For storage networks and systems, PMC-Sierra offers solutions featuring signal integrity, flexibility and diagnostics for increased system performance and management. The company provides an interconnect and controller product family for both 3G, 6G and 12G SAS/SATA storage systems and Server RAID. PMC-Sierra also provides 4G and 8G Fibre Channel controller and system interconnect products for SAN/NAS storage and switch fabric applications.
Channel Storage 
PMC-Sierra has acquired the channel storage business from Adaptec. This business has been named "Adaptec by PMC" and makes SAS/SATA RAID Adapters.
Wireline Infrastructure 
PMC-Sierra offers a broad range of interoperable communication ICs scaling from DS-0 to OC-192 for metro access, metro transport, FTTH/PON, Ethernet over SONET/SDH, Optical Transport Network (OTN) and wireless base transceiver stations (BTS). PMC is also enabling the OTN transport market with its HyPHY and META devices at 10G and 20G. PMC has more than 150 devices that help OEMs provide carrier-class solutions.[clarification needed]
Wireless Infrastructure 
PMC-Sierra semiconductor devices allow wireless service providers to deploy 2G, 2.5G and 3G wireless equipment. This includes MIPS based network processors for wireless back haul and RFICs for wideband radio modules operating in the 400 MHz to 4 GHz frequency range used by MC-GSM, CDMA2000, WCDMA, and LTE. PMC-Sierra's wireless solutions are designed to comply with current and emerging LTE, CDMA, WCDMA industry specifications.
Fiber-to-the-Home (PON) 
PMC-Sierra is the leader in gigabit EPON solutions for Fiber to the Home broadband access network equipment. PMC-Sierra is the only supplier to support EPON (IEEE 802.3ah Ethernet in the First Mile), 10G EPON (IEEE 802.3av) and GPON (ITU-T G.984) standards. PMC-Sierra system-on-chip solutions provide end-to-end gigabit per second bandwidth solutions linking central office equipment and customer premise equipment. OLT (optical line terminal) devices connect the central office to the PON network and ONU or ONT devices connect customer premises to the PON network.
Laser and Multi-Function Printers 
PMC-Sierra has discrete and system-on-chip solutions for both laser and multi-function printers. Performance scalable microprocessors from 250 MHz to 1 GHz, solutions are used by manufacturers of laser printers and multi-function printers.
Corporate Structure 
As of 2012, PMC-Sierra Global presence includes:
