Supplier Spotlight - Silicon Labs | Symmetry Blog

Nov 1, 2018


Each week, we'll be showcasing one of our suppliers from our line card and what distinguishes them from the competition. This week's supplier is Silicon Labs, a global provider of silicon, software and solutions for the Internet of Things (IoT).


Who is Silicon Labs?

Silicon Laboratories, Inc. is a worldwide fabless semiconductor company headquartered in Austin, Texas, United States. Silicon Labs provides silicon, software and solutions for the Internet of Things (IoT), Internet infrastructure, industrial automation, consumer and automotive markets.

Silicon Labs was founded in 1996 and pioneered RF and CMOS integration, developing the first CMOS RF synthesizer for mobile phones. Since the company’s inception, Silicon Labs has focused on connectivity solutions, starting with PC modems and most recently as a leading provider of solutions for the Internet of Things (IoT) with an emphasis on connectivity, performance, energy savings, and simplicity. Its products include microcontrollers (MCUs), wireless SoCs, timing devices, low-power sensors, and broadcast solutions. The company’s software stack solutions include firmware libraries, protocol-based software, and the Simplicity Studio development platform.

Silicon Labs has shipped more than 7 billion devices worldwide and has more than 1,600 patents issued and pending. Based in Austin, Texas, Silicon Labs has approximately 1,400 employees worldwide and sales, research and development offices located throughout the United States, Europe, Asia, and Australia. Silicon Labs’ customers include Samsung, Huawei, LG, Cisco, Alcatel, Harman Becker, and Technicolor.


How are they different?

Silicon Labs is involved in the development of both the ZigBee and Thread wireless protocol standards for Internet of Things devices. Silicon Labs was a founding member of both the ZigBee Board and the Thread Group, and is an associate member of the Bluetooth Special Interest Group along with being part of the Wi-Fi Alliance. Silicon Labs is a Gold member of the Open Connectivity Foundation.


What are their most popular products?

Silicon Labs provides solutions and software for use in a variety of electronic products in a range of applications including portable devices, AM/FM radios and other consumer electronics, networking equipment, test and measurement equipment, industrial monitoring and control, home automation and customer premises equipment. These products integrate complex mixed-signal functions that are frequently performed by numerous discrete components in competing products into a single chip or chipset. Silicon Labs’ portfolio is organized around four primary businesses:

  • Internet of Things - which includes 8-bit and 32-bit microcontrollers (MCUs), environmental sensors such as relative humidity and temperature sensors, and human interface solutions such as capacitive touch controllers and proximity/ambient light sensors
  • Infrastructure - which includes timing ICs (clock generators and oscillators), digital isolators, wireless ICs (2.4 GHz ZigBee SoCs and sub-GHz transmitters, receivers and transceivers)
  • Broadcast - which includes single-chip AM/FM radios for consumer radio, automotive infotainment and professional audio applications and silicon TV tuners and demodulators for flat-screen TVs and set-top boxes
  • Access - which includes analog modems for set-top boxes, point of sale terminals and multi-function printers, SLICs for VoIPgateways, and PoE devices for networking gear


Silicon Labs groups products into several product families.


Microcontrollers include 8-bit MCUs and 32-bit wireless MCUs based on the ARM architecture Cortex-M0/M3/M4 cores. This product family also includes peripheral devices such as EZRadio transceivers.



Silicon Labs offers wireless and RF IC solutions. Products include ISM band receiver ICs, wireless MCUs, FM and multi-band radio ICs, Ember ZigBee, Bluetooth and Thread 802.15.4 wireless networking solutions, and Wireless M-Bus.



Sensor products include optical, proximity, ambient light, relative humidity/temperature, heart rate, and blood oxygen level options that leverage mixed-signal capabilities.


Isolation & Power

Products include multi-channel isolators and isolated drivers] that simplify design, minimize noise, and reduce system cost.



Silicon Labs’ timing devices leverage DSPLL and MultiSynth technologies. The Timing family also encompasses PCIe and LVCMOS clock generators, clock buffers, jitter attenuating clocks, crystal and crystal-less oscillators and CDR/PHYs.


Broadcast Audio

Silicon Labs’ AM and FM receivers deliver the entire tuner from antenna input to audio output in a single chip.


Broadcast Video

Silicon Labs offers hybrid TV tuners with analog TV demodulator in a single CMOS IC that uses (iDTV) digital low-IF architecture.



Silicon Labs’s analog products include op-amps, low-power analog-to-digital converters (ADCs), comparators, power management ICs, timers, and voltage detectors and references.



Silicon Labs leverages mixed-signal design to provide a family of interface devices that enable designers to differentiate their products and speed time-to-market.


Modems & DAA

ISOmodem embedded modems leverage silicon direct access arrangement (DAA) technology and a digital signal function printers processor to deliver a globally compliant, very small analog modem for embedded applications.


Software Stacks & Development Tools

Silicon Labs provides software packages, development kits, evaluation boards, and reference designs to assist developers in completing design projects.



Offerings include short-haul applications suitable for the customer premises as well as long-haul applications suitable for the traditional telephone access systems company central office.
