AI Technical Summary

Technical Problem

In existing technologies, high-fidelity audio transmission systems are limited by channel conditions. Changing the encoding method will greatly increase the complexity of the design. Increasing the transmission rate of the channel will seriously affect the EMI (electromagnetic interference) and EMC (electromagnetic compatibility) performance of the system.

Method used

By introducing synchronization and integration units into node devices, and utilizing components such as buffer circuits, clock recovery circuits, phase detection circuits, numerically controlled delay lines, and samplers, data synchronization and integration are achieved. Port input and output directions can be flexibly configured, supporting half-duplex and full-duplex modes, enabling hybrid networking of two-line and single-line transmission, and improving transmission bandwidth.

Benefits of technology

Without changing the encoding method or increasing the speed, the bus transmission bandwidth was increased to meet different uplink and downlink bandwidth requirements, while reducing the impact of EMI and EMC.
