Vco

The VCO is able to generate frequencies in the range of 3420MHz to 3980MHz when the PLL is working properly. The frequency of the VCO signal is divided by 2or by4 in Mjoelner RF-ASIC. This allows the generation of all the frequencies in the EGSM900, GSM1800 and GSM1900 bands both RX and TX. The output frequency ofthe VCO is controlled by a DC voltage (Vc) ofthe PLL loop filter. The valid range of Vc is 0.7V- 3.8V when the PLL is in the steady state. The typical tuning sensitivity is 240MHz V....

Accessory Control Interface ACI

ACI is a point-to-point, master-slave, and bi-directional serial bus. It has three features The insertion and removal detection of an accessory device Acting as a data bus, intended mainly for control purposes The identification and authentication of accessory type which is connected The accessories are detected by the HeadInt signal when the plug is inserted. Normally when no plug is present, the pull-up resistor 100k pulls up the HeadInt signal to VFLASH1. If the accessory is inserted, the...

RF Implementation in NPL

The NPL-2 RF front-end is a triple-band direct conversion transceiver. Using direct conversion, no intermediate frequencies are used for up- or down-conversion. The VCO oscillates on the double respectively quadruplicate frequency the wanted RX or TX frequency, depending on the band used. The VCO frequency is divided by either 2 or 4 and fed to the mixers down-conversion or modulators up-conversion . Up- or down-conversion is done in one step, directly between RF frequency and base band. All...

Digital Signals between BB and RF

For the digital interfaces UPP and Mjoelner use only level shifting I0. Level shifters of both are supplied with VI0 from UEM. VI0 limits are specified in chapter 0 and have been used to calculate the limits below because VI0min is 1.72V this was used for UPP VDDSmin and not the limit from UPP which would have been 1.26V . Values are refenced to GND unless otherwise specified. Table 14 RF-BB Interface Digital Signals Table 14 RF-BB Interface Digital Signals

Charging

The charging of the main battery is controlled by the UEM. External components are needed in order to sense charging current and voltage that are needed by the Energy Management EM software and to protect against EMC into the baseband area. The charger is connected to the phone via the DCT3 bottom connector or the charger pads of the Pop-port system connector. Connecting a charger to the telephone creates a voltage, VCH, on the UEM VCHAR input. When the VCH level is detected to rise above the...

Disassembly Instructions

Press the Release Button before removing the C-Cover. Remove A-Cover as shown in the picture. Unscrew the sixT6 attaching screws, using the order shown. For assembly, the reverse order and a torque of 20Ncm must be used. Take the module from the B-Cover and unplug the display connector carefully by removing Ul-Shield from PWB. Separate the Ul-Shield from PWB carefully, because Key Dom is attached with adhesive Tape. Remove Speaker. Note the guiding pin when assembling. Take a clean cloth and...
