Description

The INAP375T together with an APIX2 receiver device offers the next generation high speed digital serial link for DISPLAY and 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 INAP375T supports popular automotive displays with video resolutions such as 1600x600 pixels and refresh rates of up to 100Hz. The device offers a flexible video interface, configurable to handle 1 or 2 independent video streams, with input interfaces such as parallel RGB (1x24 Bit or 2x10 Bit) or openLDI (“LVDS”) e.g. 2x (4 lanes + clock). Software adjustable driver characteristics and configurable operating modes allow the transmission of 3 GBit/s at distances of up to 12m over a single pair of wires. In addition to the video transmission the INAP375T provides completely independent Full Duplex Communication channels. Using the internal AShell protocol, data transfers are protected by error detection and retransmission mechanisms. Offering a Media Independent Interface (MII), the INAP375T can be directly connected to an ethernet Media Access Controller, offering full network capabilities through the APIX link. Additionally, the link is optimized to carry low latency GPIO signals for reset or synchronization purposes. The built-in audio path allows synchronous transmission of up to 4 stereo audio channels, with highly precise clock regeneration at the receiver for high-end rear-seat entertainment.
