Semitech Semiconductor Announces FSK/BPSK Power Line Communications Transceiver, Bringing Proven, Robust Communications To High Volume Smart Grid Devices

New SM2101 Chip Delivers Reliable Communications for Cost Sensitive, High Volume Smart Grid Metering Applications

Singapore, December 7, 2010 - Semitech Semiconductor, a provider of power line communications solutions that enable the transformation of the electricity grid into a smart grid, today announced the availability of the SM2101 an FSK/BPSK based power line transceiver. The SM2101 represents the next generation of power line communication transceivers, and is designed with an emphasis on Advance Metering Infrastructure (AMI) and Automated Meter Reading (AMR) applications, where low cost and high performance features are required. In addition, the SM2101 is able to meet the cost demands of high volume smart grid products such as residential meter communication with the added benefit of operating reliably in notoriously noise prone smart grid environments.

The SM2101 utilizes the ultra reliable and versatile power line transceiver components of the proven SM6401, while eliminating the embedded Flash and application microcontroller (MCU) to provide a more cost effective solution for high volume PLC applications on low or medium voltage power line networks.

"Though power line communication is favored by utilities because it is the most natural approach, and allows the utilities to move data over an infrastructure that they control, communicating over the power grid has been notoriously difficult, due to noise," noted Mike Holt, vice president of marketing and sales for Semitech. "Recognizing this, Semitech is highly focused on producing chips that enable the reliable, cost effective communication that is required for power meters, concentrators and other high volume smart grid products to 'talk' to each other. Semitech's SM2101 represents the lowest cost, highest reliability power line communications solution available today."

The SM2101 contains a complete packet data modem with the network protocol of ANSI/IEC 709.1/2 standards, allowing the development of popular narrow band PLC networks. When combined with a microcontroller (MCU), it provides a cost effective solution for data links and point-to-point, star or ad hoc networks. The SM2101 is the modem only version of the SM6401 Power Line Communication (PLC) transceiver, which utilizes the reliable and versatile power line transceiver components of the SM6401 while eliminating the embedded Flash and application microcontroller (MCU). This provides a cost effective solution for high volume PLC applications on low or medium voltage power line networks, for applications including smart metering and home automation.

The SM2101's unique capabilities include:

  • Choice of two communication frequencies on which to transmit and receive data from a list of eight factory preset frequencies to avoid interference on the power line
  • User selectable between BPSK modulation for noise immunity and compatibility to ANSI/EIA 709.1 and ANSI/EIA 709.2 devices and FSK modulation, to allow high immunity to the phase distortion
  • Approximates the amount of noise on a frequency by direct measurement and the signal strength of received packets
  • Supports CENELEC A, B and C band operation
  • Receiver sensitivity of -80dBV

About Semitech Semiconductor Pte. Ltd.
Semitech Semiconductor, headquartered in Singapore, provides the semiconductor devices that enable the transformation of the electricity grid into a smart grid. By connecting utilities to their customers, Semitech's chips help to transform homes into energy-aware "smart homes" that react to conditions on the grid, thus implementing a worldwide communications network based on the existing power grid.

Semitech's devices are used in smart meters, smart grid monitors and street light controllers to implement a connected system that is significantly more reliable and flexible than existing approaches - and interoperates well with prior deployments.
