Silicon Laboratories Inc was incorporated in August 1996 in Delaware. The Company designs and develops proprietary, analog-intensive, mixed-signal integrated circuits for a range of applications. Mixed-signal ICs are electronic components that convert real-world analog signals, such as sound and radio waves, into digital signals that electronic products can process. The Company group its products into the following categories: Broad-based products, which include its microcontrollers, timing products (clocks and oscillators), power and isolation devices, and touch controllers; Broadcast products, which include its broadcast audio and video products; Access products, which include its Voice over IP (VoIP) products, embedded modems and its Power over Ethernet (PoE) devices; and Mature products, which include certain devices that are at the end of their respective life cycles and therefore receive minimal or no continued research and development investment. The Companys main customers include Cisco, Huawei, LG Electronics, Pace, Panasonic, Sagem, Samsung, Technicolor, Varian Medical Systems and ZTE. The Company competes with Analog Devices, Atmel, Conexant, Cypress, Epson, Freescale, IDT, Lantiq, Maxim Integrated Products, MaxLinear, Microchip, Microsemi, NXP Semiconductors, Renesas, Sony Semiconductor, STMicroelectronics, Texas Instruments, Vectron International and others. The Company is subject to federal, state and local regulations, environmental controls on the storage, use, discharge and disposal of certain chemicals and gases used in the semiconductor industry.
