摘要： An integrated circuit includes a control circuit, a primary sensor device coupled to the control circuit, and a plurality of groups of secondary sensor devices coupled to the primary sensor device. The primary sensor device receives a master clock signal from the control device and outputs, to each group of secondary sensor devices, a respective secondary clock signal with a frequency lower than the primary clock signal. The primary sensor device generates primary sensor data. The primary sensor device receives secondary sensor data from each group of secondary sensor devices. The primary sensor device combines the primary sensor data and all of the secondary sensor data into a sensor data stream with a time division-multiplexing scheme and outputs the sensor data stream to the control circuit.

摘要： Systems and methods for reducing phase delay variation impact are described. A microcontroller can receive a sequence of phase offsets determined by a slave device over time. The microcontroller can determine a weight vector based on a metric associated with the sequence of phase offsets. The microcontroller can adjust a set of filter coefficients based on the weight vector. The set of filter coefficients can be filter coefficients of a filter being implemented by the slave device to filter incoming packet data.

摘要： A multimedia system for data communications. A source device communicates over a full duplex control channel of a multimedia communication link using time domain multiplexed (TDM) frames having n time slots per frame. The source device allocates a first time slot position to a virtual channel for data transmission by the source device over the full duplex control channel. A sink device communicates over the full duplex control channel of the multimedia communication link. The sink device allocates a second time slot position to the virtual channel for data transmission by the sink device over the full duplex control channel. A timing of the second time slot position is offset from a timing of the first time slot position by substantially n/2 time slots.

摘要： A microwave transmission apparatus is provided. A multiplexing unit generates multiplexed data based on a service clock rate. An interface unit writes and reads the multiplexed data at the service clock rate and a read clock rate respectively. An encoding and mapping unit performs encoding and mapping on the multiplexed data using a symbol clock rate to generate symbol data, and sends the symbol data to up conversion units. A clock tracking unit generates the symbol clock according to the system clock, and performs frequency division on the symbol clock to acquire the read clock. A stream control unit adjusts the service clock rate according to a water line error generated by the interface unit, so that the service clock rate is equal to the read clock rate. As a frequency and a phase of the system clock are fixed, even ACM switching occurs, the system clock is stably transferred.
摘要翻译：提供了一种微波传输装置。复用单元根据业务时钟速率生成复用数据。接口单元以服务时钟速率和读时钟速率分别写入和读取多路复用数据。编码和映射单元使用符号时钟速率对多路复用数据执行编码和映射以生成符号数据，并将符号数据发送到上变频单元。时钟跟踪单元根据系统时钟产生符号时钟，并对符号时钟进行分频以获取读时钟。流控制单元根据由接口单元产生的水线错误来调整服务时钟速率，使得服务时钟速率等于读时钟速率。由于系统时钟的频率和相位是固定的，所以即使发生ACM切换，系统时钟也被稳定地传输。
