Camera phone system work we will try to discuss here.
From the Start with cameras like the Nokia 6610i, 3200.7650, and other BB5. skematiknya path and it works pretty much the same system. Just a little different than the source voltage, and processor.
There is a distinguished mobile processor from IC HWA / AEM (Hardware Accelerator / auxiliary Energy Management)
There are distinguished from OMAP Golde Eye, There are distinguished from RAP.
There are phones which come from the UEM voltage, some of retu / AVILMA, and some of the Step Down DC / DC Converter / SMPS / LDO Regulators for Camera.
The most important point is bagian2 Dlm camera working conditions are:
1. Stress
There appear to function as a distinguished Analog Voltage Power / Power to the Camera. And there is the Digital Voltage yg pd data processor to function as a camera.
Analog voltage greater than TEG. Digital. Generally TEG. Analog 2.8 V range and TEG. Digital 1.8 V
2. External Clock
Each camera requires a clock as his condition, measured magnitude dpt yg stable clock here with Frequency Counter or Osciloscope will be seen the value of 9.6 Mhz 1.8 Vpp
3. I2C Control Line
On Line I2C (Inner Integrated Circuit) here is the path of the processor for camera control as indicators or check the camera. There are two tracks here are interchangeable checked CCISCL (Continuity Check Indicator Serial Clock) = Channel Clock
and CCI SDA (Continutiy Check Indicator Serial Data) = Data Channel
Control given by the Processor to the camera via the data channel based on the changes that occurred pd Clock Clock channel. So here berubah2 Clock and stable of BKN spt yg dpt EXTCLK measured.
We measure the voltage of 1.8 V which is connected with Pull Up pd Resitor this I2C lines.
4, Camera Data Line
There are 2 paths which data is sent from the processor to the camera and vice versa. And There are two paths Clocknya.
Of data sent from the processor to the camera based on clock change is happening.
Data and Clock Path is the path:
CCPCLK +
CCPCLK-
Camera Channel Processor Clock + and -
CCPDAT +
CCPDAT-
Channel Camera Clock Data + and -
For more details we refer to the following scheme:
Camera Connector Part Of Scheme can be seen as follows:
1. VCAP = Voltage at the Capacitor Storage
2. Vana = Analog Voltage for Camera (2.8 V From VFLASH1/VAUX retu / Menelaus)
3. VDIG_CAM = TEG. For Digital Camera (1.8 V From VIO / SMPS / Menelaus)
4. XSHUTDOWN = Control of the CPU to enable / disable the Camera (1.8 V)
5. EXTCLK = Clock to the Camera of 9.6 Mhz
6. CCISCL = Continuity Check Indicator Serial Clock (1.8 V) from the CPU RAP / HWA IC Camera / OMAP GOLDEN EYE
CCISDA = Continutiy Check Indicator Serial Data (1.8 V) from the CPU RAP / HWA IC Camera / OMAP GOLDEN EYE
7. CCPCLK = Channell Camera Processor Clock from CPU RAP / HWA IC Camera / OMAP GOLDEN EYE
8. CCPDAT = Channell Camera Processor Data from the CPU RAP / HW IC Camera / OMAP GOLDEN EYE
By performing the voltage measurements, Clock and Data related, then the repair cameras with interchangeable we do right and proper, so directly on target and non-menduga2 ..
Camera damage caused by the software is also retrievable. So before stepping into the hardware is better in the repair data DCC (Dynamic Camera Configuration File) If that fails the writing of this file so we can be sure there are troubled Hardware. However if the damage pd DCC file then CCPDAT Data + and - who measured pd Osci will deviate from fig reply should be.
How to write a DCC file can be with Phoenix and with MXKEY:
Service ->> Phone Test -> Camera -> Load from File -> select files DCC -> Write to Phone ...
