Digital Video Port

DVP should not be confused with the older Silicon Graphics Digital Video Port standard [12], which uses differential signaling. The modern meaning for DVP originated with Omnivision, but is now widely used by other vendors. Different DVP versions can have different bit widths, color spaces, colors transmitted per clock, and signal polarity. While many DVP cameras have a limited bit depth, there are 24 bit DVP cameras. There will be a lot of wires to connect, which may require a more expensive board. Additional wires may be needed to control the camera using an SPI, I2C or SCCB interface. The longer the wires are the lower the maximum frequency. At 100 Mhz, they can provide up to 1.66 Mpixels @60FPS.

DVP is considered a poorer cousin to MIPI (described later). But it has three advantages over MIPI.

1. All FPGAs support DVP.

2. DVP can have greater bandwidth than Lattice NX with MIPI hard cores.

3. DVP runs at much lower frequencies than MIPI, so it is possible to do debugging using less expensive logic analyzers.

4. DVP has no licensing fees.
