RM-86 Camera Module Troubleshooting Nokia Customer Care Sensitivity Camera module's sensitivity to light. In equivalent illumination conditions, a less sensitive camera needs a longer exposure time to gather enough light in forming a good image. Analogous to ISO speed in photographic film. Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture.

RM-86 Camera Module Troubleshooting Nokia Customer Care Figure 54 Blurring caused by shaking hands Movement in bright light If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting' may occur. This phenomenon is fundamental to most CMOS camera types, and usually cannot be avoided. The movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long exposure time.

SMPS Clk is 2.4MHz clock line from RAPGSM to Tahvo used for switch mode regulator synchronizing in active mode. In deep sleep mode, when VCTCXO is off, this signal is set to '0'-state. BT Clk is 38.4MHz signal from Ahne ASIC to BT module.

RM-86 System Module Nokia Customer Care FM radio The FM radio circuitry is implemented using a highly integrated radio TEA5761UK. The MCU SW controls the FM radio circuitry through I2C interface. The analogue single ended stereo output, VAFL and VAFL, are fed to the Retu’s MIC3 microphone input through 100nF capacitors. The antenna of the FM Radio is created with the headset. The wires of the headset are used as poles of the antenna. Camera The device uses 2MP SMIA camera module.

RM-86 System Module Nokia Customer Care ACI interface The ACI (Accessory Control Interface) is a point-to-point, bi-directional, single line serial bus. It has two main features: the insertion and removal detection of an accessory device and acting as a data bus between phone and accessory, intended for control purposes. A third function of ACI is to identify and authenticate the accessory. VOUT interface Accessory power is supplied by VOUT, a linear low drop-out regulator in EM ASIC (N2300) providing 2.

RM-86 System Module Nokia Customer Care Retu handles SIM card detection and the detection method is based on battery removal trough the BSI line. Due to location of the SIM card, removal of the battery causes quick power down of the SIM IF. The Retu SIM1 interface supports both the 1.8V and 3.0V SIM cards. Battery interface The battery interface supports a 3-pole battery interface. The interface consists of three connectors: VBAT, BSI and GND.

RM-86 System Module Nokia Customer Care GSM receiver functionality As GSM Rx branches are functionally identical, the following description is applicable to all of them. The received signal goes from the GSM antenna to the antenna switch module. The antenna switch module is followed by integrated LNAs residing in the Rx ASIC. The LNAs are followed by demodulators which downconvert the signal to baseband I and Q signals. The channel select filter is set to 115 kHz in the GSM mode.

RM-86 System Module Nokia Customer Care The power control loop is enabled and disabled by writing an appropriate register in N7501 RF ASIC. In case of dual slot transmission, the output power is ramped down between the consecutive slots. GSM PA module A single GSM/EDGE PA module contains two separate amplifier chains, one for EGSM900 and another for GSM1800/1900. Both amplifiers have a battery supply connection and two bias current inputs.
