Design overview

The PMP9351 is a compact power and serializer solution for automotive auxiliary camera modules using the OmniVision image sensor OV10635 . This reference board has two LMR22007 synchronous buck regulators that provide two 3.3V outputs and one 1.5V output to power the OV10635 evaluation board that bypasses the onboard LDO . This design occupies an effective PCB board area of 20x20mm . The system 9V input voltage from the rated voltage of the ECU, which is the input range of 5.5V to 20V. This reference board includes the DS90UB913Q serializer and supports a coaxial cable power configuration that allows input power and FPD-Link III signals to be transmitted over a single coaxial cable .
