APIX Multichannel SerDes Receiver with 1 Gbit/s for Video, Audio and Data


The INAP125R24 is a receiver 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 INAP125R24 video interface supports colorwidths of 10, 12, 18 and 24bit. The interface can be configured individually to match all popular display and image sensor interfaces. The pixel interface features spread spectrum staggered outputs for lowest EMI. The high-speed upstream outputs offer adjustable drive current to facilitate the adaptation to different link distances and cable qualities while offering maximum data integrity and full EMI compliance.
