Signal Processing Module for a Camera

Customer's Challenge

For its portfolio of modular cameras, our customer needed a PCB for a special application, which combines many functions. It contains a Blackfin DSP (Digital Signal Processor), SDRAM (Synchronous Dynamic Random Access Memory), flash memory and a camera interface. In addition, the board has an EtherCAT and an Ethernet interface and various serial and proprietary connections. Three PoL (point-of-load) DC/DC converters were implemented to supply power to the module itself and to the external systems, including to the analog systems of the camera. The circuit should be available as a prototype within a few weeks.

Outcome

We were able to accommodate all the required functions and the necessary connectors in the given space.

Implementation

The customer received a custom-designed circuit board in a very short time, allowing their end customer to quickly begin integrating the hardware and, most importantly, the signal processing software, into their own system. This was made possible, in part, because the board was designed almost entirely using an autorouter.
