Silicon Labs
Silicon Laboratories, Inc. (Nasdaq: SLAB) is a mixed signal fabless semiconductor company based in Austin, Texas.
The company was founded in 1996 by three veterans from the former Crystal Semiconductor – Nav Sooch, Dave Welland and Jeff Scott [1]. The company's CEO is Necip Sayiner[2]. Silicon Laboratories (NASDAQ: SLAB) designs mixed-signal ICs[3]. The company went public in 2000 and has been profitable every quarter since then. Silicon Labs leverages mixed-signal intellectual property to develop mixed-signal ICs that typically integrate a number of discrete functions on a single CMOS die. The company has leveraged it's technolog portfolio to expand into a number of large markets. The company has three main businesses:
- Access - which includes analog modems for set-top boxes, point of sale terminals and multi-function printers, SLICs for VoIP gateways, and PoE devices for networking gear
- Broadcast - which includes single chip AM/FM radios and silicon TV tuners and demodulators
- Broad-based - which includes microcontrollers, timing ICs (clocks and oscillators), digital isolators, short-range wireless receiver ICs and human interface solutions such as touch controllers and proximity sensors.
Silicon Laboratories has about 825 employees worldwide and research and development offices located throughout the US, Europe, and Asia. Silicon Labs' customers include Samsung, Huawei, LG, and Thomson.
Broad-based Products
With the acquisition of Cygnal Integrated Products, Silicon Laboratories marked their entry into the multi-billion dollar general-purpose analog and MCU markets and began building its Broad-based business, which is now 40% of company revenue. Silicon Labs’ 8-bit MCUs are based on a patented implementation of the 8051 instruction set architecture that is ‘hard wired’ implementation of the 8051 microcontroller CPU, as opposed to the original micro-coded version. The instruction set is mapped to a basic two-stage pipeline to increase throughput while maintaining an 8-bit program memory width. Silicon Labs differentiation in the market is the integration of analog peripherals to create a mixed-signal MCU that is designed to reduce the system cost without sacrificing performance. The company has also announced plans to sample a 32-bit MCU to market by the end of 2011. [4]
Also part of the company's Broad-based business are clock and oscillator products that are customizable online as well as digital isolators that replace optocouplers, short range wireless receivers and transceivers for sub GHz applications and an emerging portfolio of touch and proximity sensing products for consumer and industrial applications.
