Operational Description

MODEL:39285 BLOCK DIAGRAM DESCRIPTION BASE: (1) TRANSMISSION CIRCUIT RIGNER DETECTION : THE RING SIGNAL FROM THE LINE TO CPU VIA IC LM 324. FSK COUPING CIRCUIT: THE FSK SIGNAL FROM THE LINE TO CPU VIA 2 CERAMIC CAPACITOR. COMMUNICATION CIRCUIT: THE COMMUNICATION SIGNAL FROM THE LINE TO CPU VIA THE TRANSFORMER .. ALL SIGNAL ARE SENT FROM CPU TO ANT VIA IC AN8953FA,TX POWERAMPLIFIER, AND DUPLEXER. (2) RECEIVING CIRCUIT THE ANT PICK UP THE SIGNAL AND SEND THEM TO LINE VIA DUPLEXER,RFI AMPLIFIER & MIXER,10.7MHz FILTER,IC AN8953FA,IC LM324 AND TRANSFORMER . (3) THE ANT IS MADE BY 26 TWISTED COPPER WIRES,THE DIAMETER OF THE COPPER WIRE IS 0.15mm. (4) MCU (EM78911) MCU PROVIDES RING DETECTION, FSK DECODING ,CORDLESS PHONE CONTROLLER (5) CRYSTAL 32.768 KHz PROVIDES THE CLOCK FOR CPU CRYSTAL 4.0MHz PROVIDES THE CLOCK FOR AN8953FA. HANDSET: (1) TRAMSMISSION CIRCUIT COMMUNICATION: THE MICROPHONE PICK UP THE VOICE SIGNAL AND SEND THEM TO ANT VIA IC AN8953FA,TX POWER AMPLIFIER AND DUPLEXER. DTMF/DATA: THE KEYBOARD IS CONSISTED OF 21 KEYS, DTMF & THE DATA ARE CONTROLED BY THE CORRESPONDING KEY WHICH CONNECT TO CPU.THE CPU SEND THE SIGNAL TO ANT VIA IC AN8953FA,TX POWER AMPLIFIER AND DUPLEXER. (2) RECEIVING CIRCUIT CALLER ID SIGNAL: ANT PICK UP THE SIGNAL AND SEND THEM TO CPU VIA RFI AMP LIFIER&MIXER, 10.7MHz FILTER AND IC AN8953FA, THEN THE CPU DRIVE THE LCD DISPLAY BASE ON THE DATA RECEIVED. COMMUNICATION: ANT PICK UP THE SIGNAL AND SEND THEM TO RECEIVER VIA DUPLEXER,RFI AMPLIFIER&MIXER, 10.7MHz FILTER, AND IC AN8953FA (3) THE ANT IS MADE BY A SCREWED,NICKEL COPPER WIRE,THE DIAMETER OF THE COPPER WIRE IS 1.0mm,THE DIAMETER OF SCREW IS 4.8mm. (4) MCU PROVIDES LCD DRIVER, KEY BOARD SCANNING, DIALER&CORDLESS PHONE CONTROLLER . (5) CRYSTAL 32.768KHz PROVIDES THE CLOCK FOR CPU. CRYSTAL 4.0MHz PROVIDES THE CLOCK FOR AN8953FA.
