PMC-Sierra is an American fabless semiconductor company which develops and sells devices into the communications, storage, printing, and embedded computing marketplaces.

History[edit]

Sierra Semiconductor was originally founded in 1984 in San Jose, California by James Diller.[3] It received funding on January 11, 1984 from Sequoia Capital, and went public in 1991.

Pacific Microelectronics Centre in Burnaby, British Columbia, Canada, was spun off from Microtel Pacific Research (the research arm of BC TEL at the time) to develop Asynchronous Transfer Mode (ATM) and later SONET integrated circuits (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 a part of Verizon Communications.

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.[4] In late 1996, it acquired Bipolar Integrated Technology in Beaverton, Oregon, for about $10 million to enter the Ethernet business. The headquarters was moved to Burnaby, and in 1997, the company changed its name to PMC-Sierra. It acquired Integrated Telecom Technology Inc., San Jose, for $55 million in cash and stock in 1998.[3]

In May 2006, PMC-Sierra acquired Passave, Inc., a developer of system-on-chip semiconductors for the fiber to the home access market in a stock-for-stock transaction valued at approximately $300 million. Passave was headquartered in Boston and had a development center in Tel Aviv, Israel.[5]

On October 22, 2010 PMC-Sierra acquired Wintegra Inc. for $240 million. Wintegra had 165 employees with the majority of its development team located in Raanana, Israel, and Austin, Texas.[6]

Technology[edit]

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[15] 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.

PMC-Sierra's customers include: HP, EMC Corporation, Huawei, Cisco, Alcatel-Lucent, Fujitsu, Hitachi, Mitsubishi, ZTE and Juniper.

The company competes against 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 semiconductor companies, such as Agilent, Freescale, Intel, IBM, Infineon, Motorola, NEC, Texas Instruments, and Toshiba.

Storage[edit]

PMC-Sierra offers products for storage networks and systems.[16] The company provides an interconnect and controller product family for SAS and SATA storage systems and server computer RAID controllers. PMC-Sierra provides Fibre Channel controller and system interconnect products.

PMC-Sierra acquired the channel storage business from Adaptec. This business was named "Adaptec by PMC" and makes SAS/SATA RAID Adapters.

Wireline and optical[edit]

PMC-Sierra offers communication ICs for metro access, metro transport, FTTH/PON, Ethernet over SONET/SDH, Optical Transport Network (OTN) and wireless base transceiver stations (BTS).[17]

PMC-Sierra sells products for what is known as Ethernet in the first mile, which generally uses a passive optical network to residential areas.[citation needed]

Wireless[edit]

PMC-Sierra semiconductor devices allow wireless service providers to deploy wireless mobile phone network equipment.[18] This includes MIPS based network processors for wireless back haul and radio frequency integrated circuits for wideband radio modules.

Printers[edit]

PMC-Sierra has discrete and system-on-chip products for both laser and multi-function printers.
