The processing device may generate, at the AP, a transmission including a preamble including a physical layer (PHY) version identifier (ID) defined by a first Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. The processing device may generate, at the AP, the transmission including the preamble including one or more signaling bits defined by a second IEEE 802.11 standard. The access point may include a transceiver. The transceiver may send, at the AP to a station (STA), the transmission including the preamble.
System and methods are disclosed for hybrid phase detection and clock recovery in a serializer/deserializer (SerDes) receiver. The system enables a clock recovery unit (CRU) to dynamically operate in either a Mueller-Muller Phase Detection (MMPD) mode or an Alexander Phase Detection (APD) mode using shared circuit components. The CRU includes data and error slicers configured to generate phase error signals based on a received data stream, with the phase detector adapting the recovered clock signal accordingly. The system utilizes adjustable reference voltage levels and signal gating logic to repurpose MMPD hardware to emulate APD functionality without impacting high-speed data paths. Such architecture supports various interleaving configurations, including even-odd and n-way time-interleaved designs, and enables on-the-fly mode switching based on channel conditions or baud rate requirements.
