Rs Tx

After that, the device mounted on baseband has been identified, and the Flash Prommer down-loads the appropriate algorithm to the baseband. The programming algorithm is stored in the external SRAM on the baseband module, and after having down-loaded the algorithm and data transfer SW, the MCU jumps to the external SRAM and starts to execute the code. The MCU now asks the prommer to connect the flash programming power supply. This SW loads the data to be programmed into the flash, and implements...

Mcu

The baseband uses a Hitachi H3001 type of MCU. This is a 16-bit internal MCU with 8-bit external data bus. The MCU is capable of addressing up to 16 MByte of memory space linearly, depending upon the mode of operation. The MCU has a non multiplexed address data bus which means that memory access can be done using less clock cycles thus improving the performance but also tightening up memory access requirements. The MCU is used in mode 3 which means 8-bit external data bus and 16 Mbyte of...

Ptw

The 512 kHz clock is generated from 13 MHz using a PLL type of approach, which means that the output frequency varies as the PLL adjusts the frequency. The average frequency is 512 kHz. The clock is not supplied to the codec when it is not needed. The clock is controlled by both MCU and DSP. DTMF tones are generated by the audio codec and for that purpose, the 512 kHz clock is needed. The mCu must switch on the clock before the DTMF generation control data is transmitted on the serial control...

Tuning of Transmitter Power Levels

This adjustment loads the power levels of the phone transmitter into the EEPROM. When doing this, a pulse power meter or spectrum analyzer must be - Select Tuning - gt TX Power - Select I Q tuning values from PC's memory, phone's EEPROM or factory default values. - Set power supply voltage to 6.8 V. - Connect pulse power meter or spectrum analyzer to antenna connector. - Check that continuous mode channel 700. - Adjust the power level levels 5, 13, 15 and 19 with and - buttons and change levels...

Power Distribution

The power supply is based on the ASIC circuit PSCLD. The chip consists of regulators and control circuits providing functions like automatic power up, reset and watchdog functions. External buffering is required to provide more current. Automatic power up is needed because there is no 'power on' -button on the terminal so whenever power supply is connected to the terminal it will start automatically the power up procedure. If the input voltage is too high or too low, the terminal will...

SIM Card is Out of Order Insert SIM Card or Card Rejected

The hardware of the SIM interface from the ASIC D400 to the SIM connector X300 can be tested without SIM card. When the power is switched on, all the used lines VSIM, RST, CLK, DATA rises up to 1 first 3V and then 5 V four times. Thus the fault can be found without the SIM card in most cases.

LED Indication or Handsets display Information Contact Service

This fault means that MCU is able to run and the watchdog of the PSCLD N300 can be served. Thus PCLocals functions can be used and some information about the fault is possible to get. In principle, the fault for contact service information can be found around ASIC D400 , DSP D360 , RFI N450 , EEPROM D445 or AUDIO CODEC N130 .

Flash Programming Doesnt Work

The block diagram for the flash programming is shown in figure 12. The flash loading is handled via these components. Thus a fault in other components DSP, RFI can not prevent the flash loading. In error cases, the flash prommer can give some information about a fault. The fault information messages could be - Algorithm file or alias ID don't find In cases that the the flash programming doesn't succeed, there is a possibility to test the interface between the ASIC and the MCU. This test is useful to do, when the fault information is MCU doesn't boot or Serial clock line failure. 1. Connect a short circuit wire between the test points J400 and J401. 3. If the reset line of the MCU rises up, the interface is OK. Otherwise the reset line stays low. One must be noticed that this test can be found only short circuits, not open pins. This test indicate also that 32 kHz clock is running because of the test logic is made by using 32 kHz clock oscillator. Troubleshooting Instructions Technical...

Premicell Tfe-2

The supply voltage is measured using MCU N420 A D converter channel 0. The supply voltage supplied to the A D converter input is switched off when the baseband is powered off. The supply voltage measurement voltage is supplied by PSCLD N300, which performs switch-off, and scaling with a scaling factor of R1 R1 R2 . The measurement voltage is Filterered by a capacitor to achieve an average value that is not depending upon the current consumption behavior of the baseband. To be able to measure...

Dgnd Agnd

The baseband has one power supply circuit N300 delivering power to the different parts in the baseband. There are two logic power supplies and one analog power supply. The analog power supply VA is used for analog circuits such as audio codec. Due to the current consumption and the baseband architecture the digital supply is divided into to parts. Both digital power supply VSL and VL from the N300 PSCLD are used to distribute the power dissipation inside N300 PSCLD. The main logic power supply...
