THE WORK FLOW OF WL1805 The WL1805 PORTABLE FM STEREO TRANSMITTERis mainlyconnect of two parts: 1:the frequency modulator part. 2:the power supply circuit. Part1: The BH1417F is a FM stereo transmitter IC that transmits simple configuration. The IC consists of a stereo modulator forgenerating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulatorgenerates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator.The FM transmitter radiates FM wave on the air by modulating the carrier signal with a composite signal.Frequency is set for North America. Features 1) It is possible to improve the timbre because it has the pre-emphasis circuit, limiter circuit, and the low-pass filter circuit. 2) Built-in pilot-tone system FM stereo modulator circuit. 3) The transmission frequency is stable because it has a PLL system FM transmitter circuit. 4) PLL controls data input in parallel (4bits, 14ch for North America). Absolute maximum ratings(Ta = 25C, In measurement circuit.) Parameter SymbolLimitsUnitConditions Supply voltage Vcc 7.0 VPin8,12 Date input voltage Vin-d 0.3~VCC0.3 VPin15,16,17,18 Phase comparator output voltage Vout-p 0.3~VCC0.3 VPin7 Recommendedoperating conditions (Ta = 25C) ParameterSymbolMin.Typ.Max.UnitConditions Operating supply voltageVCC 4.0 - 6.0VPin8,12 Operating temperatureTopr -4.0 - +85°C Audio input levelVIN-A - - -10dBVPin1,22 Audio input frequency bandfIN-A 20 - 15KHzPin1,22 Pre-emphasis time constant set up range PRE - - 155uSPin2,21 Transmission frequency(200kHz step)fTX 88.7,106.7 - 88.9,107.9MHzPin9,11 Control terminal "H" level input voltageVIH 0.8Vcc - VccVPin15,16,17,18 Control terminal "L"level input voltageVIL GND - 0.2VccVPin15,16,17,18 Stereo audio signal(Pin1,22) amplified after and the 38KHz signal will be mixed and processed,then this stereo modulated signal will be add to the outside oscillator, Pin11 exportthe modulated 88.1-107.9MHz radio signal,then this signal be amplified after be send to space by oneantenna.
