MAS9191EB

DA9191EB.006 June 30,1997 MAS9191EB EVALUATION BOARD FOR CELLULAR BASEBAND ICs • Audio/Data Processor and all necessary external components • Battery Management IC and battery protection/charging circuit • VCTCXO with DAC voltage control • uP with evaluation software DESCRIPTION The Cellular Baseband evaluation board includes MAS9191A (Audio/Data Processor), MAS9129 (Battery Management) and MS8323 (VCTCXO) ICs with all needed external components and software. The two regulators of MAS9129 provide all the power for the board. The board has BNC connectors for typical MAS9191A interfaces. By using customised software and external RF parts the complete evaluation of an AMPS/ ETACS/ NAMPS phone can be performed. A general purpose micro controller is used to control the MAS9191A internal registers through a serial bus interface. For the micro controller there is 32kB SRAM, 64kB FLASH, an LCD, a keypad and an RS-232-C interface for software downloading to SRAM or FLASH. There is also a direct interface to the MAS9191A serial bus allowing an external controller to be used.

Turn on switch S1 to power up the board. The power consumption of the MAS9129 regulators can be measured by inserting an ammeter between the pins at CM1 and CM2. After powering up the system, the installed evaluation software sets up and the evaluation board is now ready for use. The power down modes of MAS9191A are controlled by register 07HEX. The default values are set by entering Register Write. See the Register write function in the next section. Rough testing of the microphone, earphone, and buzzer interfaces can be done with the MAS9191A internal loop back modes. For more detailed evaluation, a radio test set is needed. The board is assembled so that the micro controller will operate at 8.0 MHz. The micro controller can also be operated at 4.8 MHz by inserting jumper P6 and disconnecting parts X2, R23, C50 and C51. Current consumption of MAS9191A is measured at jumper CM3. EVALUATION SOFTWARE The evaluation software has the following features: - write function for changing the values of the MAS9191A registers - read function for reading the values of the MAS9191A status registers - message send - message receive A keypad serves as the software interface. The key definitions are as follows: - BACKWARD = 4 - TOGGLE =5 - FORWARD = 6 - EXIT =* - ENTER =# - UP =2 - DOWN =8 After a reset the internal registers of the MAS9191A are set to zero and the program returns to the main menu, which will display the following message on the LCD: MAS9191EB Press # for HELP MAIN MENU HELP Register Write Register Read Message Send Message Receive Display help Select Register or Set Defaults Select Register Select Message or Send Message Receive Message Edit Value Read Value Edit Message Send Messages Program flow diagram 2 DA9191EB.006 June 30,1997 EVALUATION SOFTWARE x Help Pressing “#" will display instructions for the keys shown on the LCD. Press EXIT to return to the main menu. x Main menu The FORWARD and BACKWARD keys will select “register read”, “register write”, “message send” or “message read”. The given function is executed by pressing ENTER. x Register write When entering this function the register address will be shown at the top right. After entering the write function, pressing “#' will automatically set the default values (gain controls at nominal levels and necessary switches in proper positions) to measure the transmit and receive frequency responses. The register address can be changed with the FORWARD and BACKWARD keys. The lower line will show the current contents of the register. Press EXIT to return to the main menu. The ENTER key will remove the brackets around the register address and the cursor will move to the first nibble of the hex byte on the lower line. The UP and DOWN keys will increment or decrement the nibble. If the value of the register has been changed there will be an asterisk next to the register address. The FORWARD and BACKWARD keys will move the cursor left and right, respectively. When the cursor points to a bit of a register the TOGGLE key will change the value of the bit. After a bit has been edited the top line will display the function of the bit. The ENTER key will write any new values to the MAS9191A. Press EXIT to exit from the editing mode. If the function is terminated without writing any new values, the previous values are retained. x Register read This function is quite similar to the register write function. The register address is selected with FORWARD and BACKWARD keys from the main menu. The register can be read with the ENTER key. Pressing the ENTER key a second time will update the contents of the status register. The FORWARD and BACKWARD keys will move the cursor and display the function of each bit. Return to the top line or to the main menu with the EXIT key. x Message receive This function waits for 10 messages to be received. When the messages are received they can be examined with the FORWARD and BACKWARD keys. The function can be terminated with the EXIT key. An >N= in the upper right hand corner indicates NAMPS mode. x Message send In this function six messages can be entered. First the desired message number must be chosen with the FORWARD and BACKWARD keys. Then the ENTER key will advance to the edit mode. With the FORWARD and BACKWARD keys the nibbles of each byte can be chosen and the value incremented or decremented with the UP and DOWN keys. The ENTER key will store the message into memory. The EXIT key will move the cursor to the upper row. After all messages are edited the LCD reads "SEND MESSAGES". The ENTER key will move the cursor to the lower row and the FORWARD and BACKWARD keys will choose the message. The TOGGLE key will alternate between the plus and minus signs. The plus sign indicates that the message will be transmitted. When all messages are chosen the ENTER key will start the transmission, and may be done repeatedly. The transmission can be terminated with the EXIT key. An >N= in the upper right hand corner indicates NAMPS mode. xMicro Controller and Interfaces The 68HC11 micro controller can be reset with the reset button, with DTR or by switching power off and on. In the last case the voltage regulator internal reset circuit will perform the reset. When the MOD jumper is open the controller executes the software from the FLASH ROM. When the jumper is closed the controller enters the boot-strap mode after reset. In this mode the software which contains the hl.exe program can be loaded into the FLASH ROM or SRAM through the RS-232-C interface. The syntax of the software is: el [-p] Where X is the serial port number: 1 for COM1 and 2 for COM2 and the file name is the same as the S-record file without the extension. For downloading the serial cable with the following connections are needed: PC MAS9191A 2 ----- 2 3 ----- 3 7 ----- 7 20 ----- 20 More information about the 68HC11 is available from the reference manual. P9 contains six inputs to the micro controller port PE. These inputs can be used as digital inputs or as analog inputs for the A/D-converter. When the micro controller is writing to address 0x1FFC and 0x1FFD the data is also written to the LCD command register. Write cycles to memory address 0x1FFD also change the state of the port at 0x1FFE. The port has eight outputs, ground and supply voltage. The maximum load for the power supply pin is 20 mA when operating at 3V. Keypad interface is done with port PA. Pins PA0, PA1 and PA2 are inputs from the 4x3 keypad and pins PA3-PA6 are outputs to the matrix. PA7 is the output pulse for MAS9129 watchdog circuit. All PA outputs are driven with the external buffer IC3. 3 DA9191EB.006 June 30,1997 FUNCTIONS x Battery Charging If a battery is used to power MAS9129, the battery may be charged by connecting the battery charger to the charger input. The battery charging circuit monitors the battery voltage level. When a negative slope in the charging curve is detected, the charging is stopped. The battery will be charged to 1 volt above the nominal battery voltage level. The current into MAS9129 can be monitored by jumper CM4. x MAS9129 Regulators The voltage and current levels of the MAS9129 regulators can be measured at test points CM1 and CM2. Remove the jumper and insert an ammeter to monitor the current values. Regulator 2 is enabled by jumper J2. x Microphone Interface On the evaluation board there are three possibilities for testing the microphone amplifier interface. The first way is with an on-board microphone interface, which may not be used in normal mode, but exhibits one way of implementing an interface to a microphone by using an external anti-aliasing filter. This microphone uses a DC voltage from a basic voltage divider. The diagram for this interface can be found in the schematic section. Another possibility is to use external microphone circuitry with the MAS9191A microphone amplifier using connector J1. This is done by removing the jumpers and connecting the microphone signal to pin 2 and the feedback signal to pin 1. The third possibility is to use the external microphone input EXTMIC. The electrical characteristics of the EXTMIC and MIC pins are found from the MAS9191A data sheet. x Earphone Interface The BNC-type and the header type connectors are assembled for differential type earphone output. An external earphone is supplied with the evaluation board. The board is capable of driving this earphone as well as other models directly at a 3V operation voltage. Use the BNC connector EXTEARP for external earphones. Detailed electrical descriptions of these interfaces are found from the MAS9191A data sheet. x Buzzer Interface The buzzer is driven by transistor Q1. The model of Q1 and the value of resistors R9 and R10 will affect the levels of the buzzer tone significantly. To test an external buzzer, connect it to the buzzer input pin. x Side Tone Circuit The source of the side tone is recommended to be taken from MICOUT of the MAS9191A located at pin T2. The level of the side tone is controlled by the external circuitry shown in the schematic section. The level and the frequency response of the side tone can be controlled by changing the values of components R11, R12,C43 and C44. x RX and TX Interfaces Two BNC connectors allow easy interface to RF sections or to a radio test system. The transmit audio signal as well as DTMF, ST, SAT and send messages may be monitored at the Tx connector. The receive audio signal as well as SAT and receive messages are measured by applying the signals to the RX connector. There are 22nF DC blocking capacitors on both interfaces. The electrical characteristics can be found from the MAS9191A data sheet. x Microphone and Rx Audio Level Measurement The two internal operational amplifiers of the MAS9191A are used to measure audio levels. The level measurement is done with the circuit shown in the schematic section. The level detection output is monitored by the micro controller A/D converter. To examine the operation of the level detector, measure test points T6 and T7. x Test Points There are seven test points along the Rx and Tx audio section. These test points can be used to measure gain control levels and the performance of the compressor, expander, limiter and all filters. The pin description section defines all test points. x CTRL Interface The CTRL connector consists of the control signal TXCTRL for the transmitter and two test indicators BUSY and TXON. TXCTRL is an open collector output and is low only when a transmission collision occurs. After a collision TXCTRL goes to a high impedance state and the TX block of the MAS9191A is reset with TXRST. x Three 8-bit DAC Outputs The DAC connector contains a direct interface to the three MAS9191A internal 8-bit DACs. x MAS9191A Serial Bus Interface The five row jumper for the MAS9191A serial bus to the micro controller is normally closed. Remove the jumpers for external control. The STB, SCL, SRXD, STXD and XINT signals are located at pins 1, 2, 3, 4 and 5 respectively. x MS8323 Output Frequency The output frequency of the VCTCXO can be measured from test pin OSCOUT. The DAC1 output from MAS9191A is the voltage control for the VCTCXO which adjusts the output frequency. Jumper J3 connects DAC1 to VCONT. The current consumption of the VCTCXO can be measured through jumper CM5. 4 DA9191EB.006 June 30,1997 CONNECTOR DESCRIPTION Connector name Battery Pin Function NiCd Battery or external DC power supply capable of driving at least 200 mA current is connected to battery input.
