Multi-chip synchronization in sensor applications

A method for a system comprising a plurality of devices coupled to one another via a shared digital wired communication link, the method comprising:

• periodically transmitting, by a first device of the plurality of devices, a synchronization packet onto the shared digital wired communication link to synchronize other of the plurality of devices to a reference clock of the first device;
• receiving, by a second device of the plurality of devices, the synchronization packet;
• transmitting, by the second device, one or more first data packets onto the shared digital wired communication link in response to the synchronization packet;
• receiving, by a third device of the plurality of devices, the synchronization packet;
• and
• transmitting, by the third device, one or more second data packets onto the shared digital wired communication link in response to the synchronization packet and the one or more second data packets.
