A transceiver device includes a transmitter and a receiver connected through first and second lines. A first frame period includes an active period for transmitting a first payload and a vertical blank period including a frequency hopping period. The transmitter transmits, to the first and second lines, signals having a first voltage range in a first mode and signals having a second voltage range in a second mode. The transmitter generates a first horizontal synchronization signal in the second mode except for the frequency hopping period, encodes the first horizontal synchronization signal to horizontal synchronization data, and generates a second horizontal synchronization signal in the first mode in the frequency hopping period. The transmitter adds a first clock training pattern to the horizontal synchronization data except for the frequency hopping period, and adds a second clock training pattern to first horizontal synchronization data after the frequency hopping period.

A synchronizer can include a symbol estimator, an inner-pattern de-mapper, a timing tracker, and a correlator. The symbol estimator can be configured to estimate one or more symbols of a received signal based on a phase signal. The inner-pattern de-mapper can be configured to de-map the one or more symbols to generate an inner-pattern de-mapped symbol estimation. The timing tracker can be configured to accumulate the inner-pattern de-mapped symbol estimation and to determine a peak position based on the accumulated inner-pattern de-mapped symbol estimation. The correlator can be configured to correlate the accumulated inner-pattern de-mapped symbol estimation based on a reference signal. The correlation of the accumulated inner-pattern de-mapped symbol estimation can be independent of a signal over sampling rate (OSR). The synchronizer can be adapted in a long range Bluetooth low energy (BLE) receiver.

A radio transmitting device configured to transmit a spread-spectrum radio signal wherein a carrier frequency changes in a predetermined set of radio channels according to a hopping sequence, the radio signal being organized in packets having each a header transmitted at a first channel in the hopping sequence comprising a detection sequence, and payload data encoding a message transmitted at following channels in the hopping sequence.

A radio communications device includes a RTC configured to run even during sleep for receiving from a coordinator node (CN) in an asynchronous channel hopping WPAN an asynchronous hopping sequence (AHS) frame that includes the CN's hopping sequence. A processor implements a stored sleepy device operation in asynchronous channel hopping networks algorithm. The algorithm is for determining a time stamp for the AHS frame and the CN's initial timing position within the hopping sequence, storing the time stamp, going to sleep and upon waking up changing a frequency band of its receive (Rx) channel to an updated fixed channel. A data request command frame is transmitted by the device on the CN's listening channel that is calculated from the CN's hopping sequence, time stamp, CN's initial timing position and current time, and the device receives an ACK frame transmitted by the CN at the updated fixed channel of Rx operation.
