Abstract
Techniques and mechanisms for communicating packets of image information, the packets each having a respective format that is defined or otherwise indicated by a camera serial interface standard. In an embodiment, circuitry of a first physical layer (PHY) is operated to facilitate such communication via a lane of an interconnect that is coupled between the first PHY and a second PHY. The PHYs further communicate between each other a packet delimiter sequence between two such packets. In another embodiment, the plurality of packets and the packet delimiter sequence are communicated after a transition of one PHY from a relatively low power state, and prior to any subsequent transition of that PHY back to the relatively low power state. The camera serial interface standard specifies or otherwise indicates a protocol whereby a transition to such a low power state is performed between the respective communications of any two successive packets.
