Automotive Camera Module Reference Design for Uncompressed Digital Video With Wide Vin Front End (PMP10653)

PMP10653.1 is an Optimized Automotive Camera Module Design for Uncompressed Digital Video over Coax cable. The design is broadly divided into four Blocks. Power Block: This design support Wide Vin, i.e., 4.5V-36V. LM53601 is used for first stage DC/DC conversion, which can deliver 1A at 3.3V output. This device is synchronous, fully integrated and 2.1MHz switching which results in highly integrated design. Two ultra-low noise LDOs (LP5907) are used to power noise susceptible image sensor as well as serializes. Serializers: 12-bit Serializer DS90UB913A is used which offers a FPD-Link III interface with a high-speed forward channel and a bidirectional control channel for data transmission over a single coaxial cable or differential pair. Digital image Sensor: Omnivision’s OV10640 image sensor is used which utilizes backside illumination technology, enabling industry leading sensitivity. Power Supply filter: One of the most critical portions of a design which uses Power over Coax is the filter circuitry. The goal is twofold: 1) deliver a clean DC supply to the input of the switching regulators; and 2) protect the FPDLink communication channels from noise coupled backwards from the rest of the system.
