Global IP Core Launches Licensable Zigbee Transceiver PHY IP Core

August 5, 2026  – Global IP Core rolled out the Zigbee Transceiver PHY IP Core for instant implementation. The IP Core is available for the Satellite Communication and Aerospace & Defense industry. The modulation and spreading functions for the O-QPSK PHYs are processed through 3 steps. First, each 4 bits are gathered to represent 1 symbol, which has a value from 0 to 15. Second, each symbol is used to select among 16 PN sequences called chip. Finally, each chip is modulated using O-QPSK with half-sine pulse shaping. 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.
