In some cases, mobile Application Processors (AP) may not have enough interfaces to support the number of image sensor inputs required for a particular application. In other cases, the processing latency between image sensors and imaging data may be too large. The Lattice Semiconductor Dual MIPI CSI-2 to Single MIPI CSI-2...

The first rule of war is “know your enemy”. It is the same principle with Solid State Lighting (SSL) – if you don’t understand how an LED behaves, don’t be surprised when your application doesn’t succeed.
LEDs are non-linear devices. If a low voltage is applied to an LED it does...
