3.NeoTel-811_circuit_description.DOC 6 / 32 3. Circuit Description In this section, the description for functional blocks of each PBA is explained. Though NeoTel-811 consists of independent PBA’s such as main board, keypad, and sub-key board, PBA’s are connected via various cables with one another. Main board is connected to keypad board with 30-pin FPC cable. Keypad board is connected to LCD module with 16-pin connector, and keypad board is connected to sub-key board with 6-pin cable. Main board adopts a pair of 60-pin connectors to connect with CDMA module. CDMA module consists of two boards, which are CDMA baseband module and RF module. CDMA baseband module and RF module are inter-connected with 60-pin connector. 3.1 Main Board The block diagram of a main board is shown in Figure 3. Each block is explained in the subsequent sections. The speaker phone block is included in the main board, however components are not assembled currently. It can be modified according to the customer’s request. Figure 3. 1. Block Diagram of Main Board. Power Block Serial Communication CDMA Module Interface LCD / Keypad Interface Audio I/O 3.NeoTel-811_circuit_description.DOC 7 / 32 3.1.1 Power Block Figure 3.2. Power Block Diagram of Main Board. The block diagram of a power block is shown in Figure 4. Main board supplies all the power used in NeoTel-811. Main board uses DC 9V/1.5A from SMPS as a main power and 7.2V battery as a backup power. The power block consists of charging circuitry, power on/off circuitry, VPWR, 4V output, 4.6V output, and 3V output. Battery is rechargeable Ni-Cd cells with 7.2V/900mAh capacity. Battery can be replaced to Ni-MH cells with 7.2V/1600mAh in order to enhance time for usage. Battery is continuously charged when the SMPS is plugged in AC voltage regardless of the status of power switch. If failure occurs in the main power from SMPS, the power is changed to backup battery. The power switch has three modes of operation, which are OFF, Powering OFF, and ON. When the power switch is on ON state, PS_CTRL signal from MSM3100 controls terminal to ON state. When the terminal operates with battery, MSM3100 controls PS_CTRL signal to turn out the power of terminal in case of failure of battery power. VPWR is used for circuitry of serial communication with PC. The regulator for 4V output is used for CDMA module. The regulator for 4.6V output is used for audio interface and LCD/LED driving logic. External DC Power (9V DC) Electrical Switch (SI3443) 3V Regulator 5V Regulator 4V Regulator Charge Logic Battery 7.2V Power ON/OFF Logic Power Switch PS_CRTL (From MSM3100) VPWR 3.NeoTel-811_circuit_description.DOC 8 / 32 Finally, the regulator for 3V output is used for power logic driving and serial communication line driving. 3.1.2 LCD / Keypad Interface Figure 3.3. Block Diagram of LCD / Keypad Interface. The block diagram of LCD/Keypad interface is shown in Figure 5. Though LCD/keypad interface has no relation with CDMA module, it controls almost UI (User Interface) functions. LCD/keypad interface consists of 30 signals for keypad, sub-key board and LCD. The signals comprise 10 lines of keypad data, 7 lines of LED drive, 3 lines of LCD drive, and 8 lines of LCD display data. The input power for LCD/keypad interface is 4.6V from 5V regulator in power block of main board. MSM3100 senses key input using key-sense block and GPIO signals. The control signals for LED’s are as follows: two lines for RSSI level, two lines for battery level, and one line for message indication. The LED for RSSI level shows three levels of signal strength such as green, yellow, and red. The LED for battery level also shows three levels of remaining battery level such as green, yellow, and red. The LED for message LCD / Keypad Interface (30 Pin Connector) CDMA Module ( 2X60 Pin Connector ) Keypad [0:9] LCD Data [0:7] LCD Driver Logic LED Driver Logic LCD Data [0:7] LED Lines LED Lines 5 V Regulator Output 3.NeoTel-811_circuit_description.DOC 9 / 32 indication is ON when new message is received. All the LED’s are controlled by LED driver logic on main board. Three lines of LCD driving signal and one line of LCD backlight enable line are directly controlled by MSM3100 through LCD/keypad interface on main board. Eight lines of LCD display data are controlled by LCD driving logic pulled-up to 4.6V on main board. The enable line for LCD backlight can be controlled to ON/OFF by electric switch on keypad board. 3.1.3 Serial Communication : UART, DM Figure 3.4. Block Diagram of Serial Communication Block. The block diagram of serial communication block is shown in Figure 6. The serial communication block provides interface for data communications, which uses UART part inside MSM3100 and some GPIO signals. This block is designed to convert logic signals inside MSM3100 to RS-232 level, which can be connected to PC through RS-232 9-pin connector.

Block Diagram of Audio Input/Output. The block diagram of audio input/output is shown in Figure 7. This block interfaces vocoder block and internal Codec inside MSM3100, which enables the user’s communicating with handset. The audio I/O block interfaces internal Codec inside MSM3100 with microphone and speaker in the handset. The speaker-phone function is implemented in circuitry, however the components are not assembled currently. The speaker- phone function can be provided in case of customer’s request.
