Multi-Chip Sensor Synchronization Without External Clock Routing

The external clock source is extracted and replaced by a virtual clock mechanism implemented through software/firmware. Each device generates its own timing references based on local oscillators, and synchronization is achieved through exchange of timing information packets rather than physical clock signal distribution. This eliminates the need for external clock routing while maintaining synchronization precision.

A timing synchronization protocol acts as an intermediary between devices. Instead of directly sharing physical clock signals, devices exchange timing information through communication packets that contain timestamp and synchronization data. This intermediary layer allows precise synchronization without requiring direct clock signal paths between devices.

The synchronization system dynamically adjusts timing parameters based on measured variance between devices. Each device measures its timing offset relative to others and dynamically compensates by adjusting its local timing references. This dynamic adaptation allows the system to accommodate timing variance without requiring excessive reserved time slots, as the actual time penalty is minimized through active compensation.

A feedback mechanism continuously monitors timing synchronization status and adjusts device timing parameters accordingly. Devices exchange timing information and use this feedback to correct their local clock drift and timing offsets. This closed-loop approach minimizes the time penalty by actively reducing timing variance rather than statically allocating large time buffers.
