The INAP125T24 is a transmitter for the new Automotive PIXel (APIX) link for display and camera based point-to-point applications. The APIX link features an uni-directional pixel and full-duplex sideband data transmission over one single pair of shielded twisted pair (STP) copper cable. The upstream sideband can also be transmitted over a separate pair of wires to serve the requirements for automotive applications. In addition this wire may be used for power supply.
The INAP125T24 video interface supports color widths of 10, 12, 18 and 24bit. The interface can be configured individually to match all popular display and image sensor interfaces. The pixel interface is able to handle a wide spread pixel clock for lowest EMI.
The INAP125T24 transmitter features dedicated high-speed outputs with adjustable drive current and pre-emphasis to facilitate the adaptation to different link distances and cable qualities while offering maximum data integrity and full EMI compliance.
