Thanks for the valuable inputs. The master clock signal is derived from within the sensor board using an oscillator. I am getting 11.2 Mhz clock to the sensor. The host interface includes Data lines (d0 to d7), pixel clock, line valid and frame valid signals. All these are output signals.Currently these wires are not connected to the host and are left open. I have only connected, SDA, SCLk and power to the sensor board. When I run i2cdetect, some devices on the host i2c-0 bus are getting detected at the address 0x50, 0x51 etc. But my Sensor board is not getting detected. Please advice.

Some cameras, including Micron cameras, do not reply to i2c commands until the camera interface (master clock) is activated.
