Circuit Description of Digital Cordless Telephone (XG-2500) The XG-2500 Digital Cordless Telephone with caller ID is 2400MHz band(ISM BAND) Digital Cordless Telephone and Time Division Duplex (TDD) System. It performs Transmission and reception through the TDD ANTENNA of the RF module. Is has 40 channels and General RF specifications are below. █ Remote & Base 1. Frequency (BASE & PORTABLE) : 2404.8MHz ~ 2475.0MHz 2. Antenna : Time Division Duplex 3. Number of Channel : 40 Channels 4. Channel Space :1.8MHz 5. Receiver Sensitivity(BER) :Less than 0.1%@ -104dBm 6. RF Output Power :Automatic RF Power Control High – Power Mode : 14 ± 2 Medium-Power Mode :4 ± 2 Low-Power Mode : -8.5 ± 2 7. Processing Gain :10.8dB 8.Type of Modulation :DBPSK 9.Speech Coder :32kbps ADPCM 10.Symbol Rate :1.2Mbps 11.ID Code :More than 2E24 12.Battery Capacity : Capacity 230mAH (3.7V) :Talk Time 2 Hours :Standby Time 7 Days 13.Power Supply Voltage for Remote Battery : 3.7V Li-polymer 230mAH 14.Power Supply Voltage Adaptor for Base unit :9VDC / 300mA BASE Station and Handset unit 1.1 Power supply and Regulator circuit (Base station) - AC/DC adaptor converts 120V AC/60Hz to DC 9V 300mA supplies 9V DC to the base unit. - Regulated voltages used U5(S7805D) 1.1.1 Power supply and Regulator circuit (Handset unit) Supply the Battery 3.7V 230mAh Li-polymer and voltage regulator U3 (3.0V output) 1.2 Park Detect and Battery Charger - When the handset is parked, the charge signal is connected between the battery charger circuit (Q5, Q6) and the handset battery. Current will flow to charge the battery and turn on the Q7 TR ON. Q7 will set the PARK(Pin 25) signal low, which will inform the base station that the handset is parked. trickle charged Li-polymer is use, the Nominal charge current must be close to but less than 0.1C. Nominal charge current should be 100~120mA for the battery. 1.3 Speech circuit (Base station) 1.3.1 FS1, VAR1(Varistor) is for surge protection and there are RF interference protection components L1, L2 and C55. 1.3.2 U1, C1, R1 and ZD1 are for ringer circuitry. When the base unit receives a ring signal, a pulse on pin 4 of U1 inputs pin 4 of U3. 1.3.3 When there is an audio signal on telephone line, the audio signal through U7A applies Pin 37 of U3 (Baseband chipset IC) for convert analog signal to digital signal. When converted signal outputs from pin80 of U3 TXDAC and send to the RF module. 1.3.4 Receive signal from handset is detected by RF module then De-modulation by the U3. Pin 81(RXIP), 82(RXIN), 83(RXQP), 84(RXQN) reserved audio signal output to keep proper level. The audio level is adjusted by U7 and supplies to telephone line. 1.3.5 U3 Baseband Chip ASIC Block Diagram Fig 1 Figure1-U3 BASEBAND ASIC The Partitioning of the U3 Baseband ASIC logic blocks is show in Figure1. Detailed information on Each of these block follows. 1.3.5.1 Microcontroller The microcontroller is the 65C02 based MC19 CPU. 1.3.5.2 Baseband Modem – A block diagram of the baseband Modem is shown in Figure 2. - Transmitter/Receiver Data Paths. The transmit data path is comprised of a parallel-to serial converter, scrambler, differential encoder, spreader and modulator. The receive data path is comprised of analog to digital converters, a matched filter with frequency compensation, data demondulator, descrambler and serial to parallel converter. - Scrambler / Descrambler. A16 bit code ramdomizes the voice and supervisory data for transmission and reception. More than 64K scramble codes are available form the 16 bit maximal length pseudo noise sequence generator. - Differential Encoder. Data is differentially encoded. - Modulation. BPSK modulation is used. - Receiver A/D Converters. Baseband I/Q signal from the radio are sampled at 2.4GHz and converted to digital with 3 bit flash A/D converters. - Frequency Compensation. Frequency compensation circuit allow use of high PPM crystals. - Data Demodulations. Matched filter outputs are differentially demodulated using dot product detection. - Matched Filters. The spreading code is removed from the received digitized I/Q signals with matched filters. - AGC.(Pin87) The signal energy is compared to a programmable threshold and scaled with programmable gain. The digital AGC value is output to the radio by an 8 bit D/A converter. - ID Detector.(Pin 24) A 16 bit code program a 32 bit ID word which is used during acquistion to verify the RF link and initialize from timing. - RF Control Functions. The U3 Baseband ASIC four GPIOs are for the RF synthesize serial Interface. In addition, the 9.6 MHz REFOSC signal is used as the synthesizer reference clock. Furthermore, two GPIOs are used to control the RF power amplifier output level, One GPIO is used to control the LNA gain setting and two dedicated signals are used to control switching of the RF transmit and Receive modes. - External Interface Functions ·General Purpose I/O Pins, Keypad/ Switch/LED display , Asychronous receiver/ transmitter (ART), Park Detector. etc. ·Serial EEPROM interface. The U3 Baseband ASIC supports the use of industry standard microwire or I’’C serial EEPROM. Ringer/Buzzer interface. The U3 Baseband ASIC provides several otions for generating ringer tones. LED Indicator Interface. The U3 Baseband ASIC provides the LED indicators. (Phone, Page/Intercom, Charge, Our of range/Low battery) 1.3.6 Switches (Base Station only) The switch input are available using the KEYPAD control pins to scan the switches and GPIOC0 (Pin 5) to detect a closed switch, using a method similar to the keypad matrix scanning. The base station circuit interface for the RINGER ON/OFF switch (Not used) 1.3.7 KEYPAD (Handset only) The keypad is controlled by 14 pins (8 bidirectional control and 6 read inputs). 1.3.8 Asynchronous Receiver / Transmitter (ART) This block can be configured as either as Asynchronous Receiver Transmitter (ART) or as a standard time the logic controls the two-pin asynchronous serial port of the ASIC. It can be used for b…
