The INAP378TAQ together with the INAP378RAQ receiver offers the next generation high speed digital serial link for CAMERA applications. It provides a DC-balanced, AC coupled low latency, point-to-point link over shielded twisted pair (STP) cables. Its scalable physical layer provides bandwidth of up to 3 GBit/s at lowest EMI. The INAP378TAQ supports popular automotive image sensor solutions with video resolutions such as 1280x800 pixels and refresh rates of up to 45fps. The device offers a parallel video interface for support of up to 16 color bits + 2 control bits. Software adjustable driver characteristics and configurable operating modes allow the transmission of 1.5 GBit/s at distances of up to 25m over a single pair of wires. In addition to the video transmission the INAP378TAQ provides completely independent Full Duplex Communication channels. Using the internal AShell protocol, data transfers are protected by error detection and retransmission mechanisms.
Additionally, the link is optimized to carry low latency GPIO signals for reset or synchronization purposes.
