Zigbee Transceiver PHY
The Receiver scans the incoming data from the digital mixer for a preamble. Once a preamble is detected, the Start of Frame Delimiter (SFD), frame length, and other receiver status information is sent to the upper layer. Additionally, the payload data is written to the received data buffer to create the PSDU packet, which is transferred to the MAC layer when requested. The PHY notifies the MAC layer for arrival of MAC Protocol Data Unit (MPDU) along with the LQI information via an interrupt. If a valid preamble is not detected, it gives feedback to the packet time error detection block to restart the energy detection process. The design includes ED and LQI circuits to support CCA modes by MAC defined in IEEE 802.15.4.
The design includes a standard 32-bit AHB-lite, slave interface version 3.0, with registers as defined in the Register Description section of the Datasheet.
