The Pcam 5C is an imaging module meant for use with FPGA development boards. The module is designed around the Omnivision

OV5640 5 megapixel (MP) color image sensor. This sensor includes various internal processing functions that can improve image quality,

including automatic white balance, automatic black level calibration, and controls for adjusting saturation, hue, gamma and sharpness. Data

is transferred over a dual-lane MIPI CSI-2 interface, which provides enough data bandwidth to support common video streaming formats

such as 1080p (at 30 frames per second) and 720p (at 60 frames per second). The module is connected to the FPGA development board via

a 15-pin flat-flexible cable (FFC) that is pin compatible with the connector found on the popular Raspberry Pi development board. The

Pcam 5C comes with a 10 cm flat-flexible cable and a factory-installed fixed focus lens with M12 lens mount, so it is ready to use out of the

box.

2/17/2018 Pcam 5C Reference Manual [Reference.Digilentinc] Image sensor break-outs such as the Pcam 5C can only be controlled by an SoC with a MIPI CSI-2 controller in hardware and using them requires complicated software that properly configures the controller and the sensor. When trying to implement a method of using such a break-out with an FPGA host, there are two realistic options: 1. Pay a license fee to acquire MIPI CSI-2 IP that is designed to work in FPGAs.

2/17/2018 Pcam 5C Reference Manual [Reference.Digilentinc] Further information on the details of MIPI CSI-2 and D-PHY are beyond the scope of this document. Digilent provides open source MIPI CSI-2 and D-PHY Vivado IP cores that can be studied to learn more. These IP cores are included in the  Digilent Vivado Library (https://github.com/Digilent/vivado-library). Serial Camera Control Bus (SCCB) The SCCB on the Pcam 5C is a two-pin bus used to access the control registers for the OV5640 image sensor.

Many suitable M12 lenses with a range of unique characteristics are available for sale from third-party vendors. Care should be taken when choosing a third party lens to ensure it is appropriate to use with the OV5640 image sensor and the Pcam 5C lens mount. Some longer lenses may make contact with the image sensor if over tightened, which could cause damage.

2/17/2018 Pcam 5C Reference Manual [Reference.Digilentinc] The Pcam 5C PCB was designed to allow for the incorporation of circuitry that can drive an auto-focus M12 liquid lens assembly, such as those created by  Varioptic (http://www.varioptic.com/products/auto-focus-lens-modules/). The circuitry needed to drive a liquid lens assembly is not loaded in the current version of the Pcam 5C (see page 2 of the Pcam 5C Schematic (https://reference.digilentinc.com/_media/reference/add-ons/pcam-5c/pcam_5c_sch.
