Analog Front End for Power Line Communication: ANS6201

Analog Front End for Power Line Communication: ANS6201

The real world problem

Power Line Communication is more and more considered as one of the solutions to transmit data from and to smart meters in a reliable, accurate and secure manner.

The power line system differs around the world.  These variations are at a technical level with different voltage levels, other wiring schemes, another structuring of the grid, etc…, but also on EMC-standards and communication protocols. So, the probability that one single Power Line Communication standard will be used all around the world is close to zero.

Smart grid and smart home applications are still evolving, imposing new requirements, such as higher data rates, low power and larger networks, on Power Line Communication technologies.  Installation, maintenance and replacement of smart meters and communication modules are very expensive requiring systems with a long lifetime.

To cope with these variations and these evolutions, flexible and upgradable solutions are needed.

The solution

The solution

AnSem has developed a single chip Analog Front End for Narrow Band Power Line communication (ANS6201) that has configurable blocks on board.  This Software Defined AFE chip can be used around the world without major adaptations of external components.  The highly integrated AFE also reduce the external Bill of Materials.

The flexible approach that AnSem has chosen for this AFE creates opportunities to adapt to multi standards and to upcoming protocols. This will enhance the lifetime of the hardware platform under the evolving requirements of the smart grid and smart home applications.

The blocks on the ANS6201 are designed to obtain an optimal signal sensitivity under the harsh and variable conditions of the Power Line allowing higher data rates and longer distances between transmitter and receiver.
