Semitech Semiconductor, a provider of power line communications (PLC) solutions supporting conversion of the electrical grid into a smart grid, has announced the release of SM2400 device, a multi-standard OFDM based PLC transceiver. Providing optimized flexibility, the SM2400 has been designed to function easily across a number of noisy smart grid environments which complying with pre-determined standards and proprietary modes.

Requirements within a specific region and the standards that govern that region create communication complexities in noise prone power grid environments. Incorporating a cost-effective architecture, the SM2400 is ideal for PLC applications delivering high level of programmability to support compliance with multiple communications programs and standards. Based on a dual core design, the SM2400 has been developed to ensure enhanced communication performance without compromising on flexibility and programmability on a number of standards such as the OFDM standard. Additionally, the device, which is Semitech's OFDM based second generation solution, ensures proprietary and personalized implementations.

The SM2400 can be deployed for a number of applications that need communication over a power line such as an advanced metering infrastructure and for automated meter reading, for controlling street lighting, home, and building automation among other such deployments.

Capabilities and enhancements of the SM2400 include a number of operation modes that support OFDM standards and compliance with IEEE (News - Alert) 1901.2, G3-PLC, and PRIME in addition to supporting a flexibility to address new and future standards and special proprietary modes.

The device features a dual core design comprising of custom PLC DSP and Data Link Layer 32bit controller combining Physical Layer (PHY) and Media AccessController (MAC). Semitech's SM2400 comes in a programmable 5-500 KHz range operational band which is compliant with CENELEC, FCC (News - Alert), and ARIB bands operation. In addition to delivering high speed and reliable communication, the device is power optimized with an integrated AFE and differential and coherent BPSK, QPSK and 8PSK.

Headquartered in Singapore, Semitech Semiconductor is a provider of semiconductor devices that have been developed to convert an electricity grid into a smart grid. By enabling delivery of utilities to customers, the company has been a pioneering driver in transforming homes into energy conserving "smart homes" capable of responding to conditions on the grid.
