Looking to simplify wireless connectivity in embedded applications, Silicon Laboratories has introduced two wireless ics which it says offer next generation performance.
The EZRadio Si4455 transceiver and Si4355 receiver cover the 283 to350MHz, 425 to 525MHz and 850 to 960MHz frequency bands, and offer 13dBm output power with -116dBm sensitivity. The devices are designed for low power operation in battery backed applications and offer a standby current of 50nA, with an active transmit current of 20mA at 10dBm and a receive current of 10mA. To make configuration more straightforward, the devices include the GUI based EZConfig configuration tool to help guide developers through an optimal setup process based on the needs of their application. "Recognising the traditional complexity of adding RF connectivity to embedded systems, we designed the new Si4x55 EZRadio wireless ics and development tools to provide the utmost ease of use without sacrificing performance," said Diwakar Vishakhadatta, vp and general manager of Silicon Labs' wireless embedded products. "Our EZConfig software makes it easy to add state of the art sub GHz transceivers and receivers to any application."
