Description

The INAP375R together with an APIX2 transmitter 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 INAP375R 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 output interfaces such as parallel RGB (1x24 Bit or 2x10 Bit) or openLDI (“LVDS”) e.g. 2x (4 lanes + clock). Software adjustable driver characteristics at the transmitter, combined with the powerful adaptive equalizer 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 INAP375R 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 INAP375R 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 inbuilt 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 applications.
