Overview

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.
