Receiver Clock Recovery IC Provides Radio Interface

The Extractor 1000 is a receiver clock recovery IC that provides an interface between the company's RX and TR series ASH radios and a low-cost host microcontroller. The device performs clock recovery and start symbol detection, eliminating the need for the user to develop these complex RF UART functions. In addition to the radio interface and RF UART implementation, the device allows the receiver to run at zero threshold, permitting the receiver to run at maximum sensitivity without burdening the real-time processing power of the host controller. Also, the µC can run in a low-current mode while the chip is searching for a start symbol. Only when a start symbol is detected and incoming data is present will the device wake up the host controller. The chip is designed for use in applications such as industrial and home automation, remote control systems, data logging and HVAC management.
