Module Introduction SCCB is the Serial Camera Control Bus, which is customized by OmniVision; it is used to perform Read/Write operation for the Register of the camera in order to control the image output of the camera. The SCCB is similar to the I2C; they are both a kind of bidirectional Synchronous Protocol Analyzer. SCCB includes a Clock Signal Line, SIOC, and a Data Signal Line, SIOD; otherwise, there is a Chip Select Control Channel, SCCBE, and it is effective in the Low Level. The Transmission Speed of SCCB is 100K/S or 400K/S. The Data Transmission of SCCB is controlled by the Master Device. The Master Device can send out the Data Transmission Activating Signal, Clock Signal and the Stop Signal when ending the transmission, and a Master Device can transmit data to several Slave Devices. When the SCCBE is in the Low Level, the signal starts at the time when SIOC is in the High Level and there is a Falling Edge on SIOD, and ends at the time when SIOC is in the High Level and there is a Rising Edge on SIOD; the data transmission is latched at the Rising Edge of SIOC, and the data is converted at the time when SIOC is in the Low Level. Application Field It is applied in the Image Sensor of the OV Series, such as OV7620, OV3640 and so on. 【DOWNLOAD】
