BL3361

BL3361 LOW POWER NARROW BAND FM IF BL3361 DESCRIPTION The BL3361 is designed for use in FM dual conversion communication. It contains a complete narrow band FM demodulation system operable to less than 2.0V supply voltage. This low power narrow band FM IF system provides the second converter, second IF, demodulator. Filter Amp and squelch circuitry for communications and scanning receivers. F E AT U R E Operating voltage range : 2.0V ~ 8.0V Low Current consumption ICC=3.9mA Typ. (VCC=4.0V) Excellent input sensitivity (-3dB Limiting = 2.6 µVrms Typ.) Low number of external parts required Operating frequency up to 60MHz Encapsulation： SOP-16 PIN CONFIGURATION Page1 www.belling.com.cn V1.2 ABSOLUTE MAXIMUM RATINGS (Ta=25°C) BL3361 Characteristic Max imu m Su pp ly Vo lta ge Supp ly Vo ltag e Ra nge Dete c to r Inp ut Vo ltag e R F In pu t Voltage Mute Function Junction Temperature Power Dissipation Operating Temperature Storage Temperature Symbol Vcc(MAX) Vcc VIN(DET) VIN(RF) VMUTE TJ PD Topr Ts t g Va l u e 10 2.0~8.0 1.0 1.0 -0.5~+5.0 150 1.5 -30~+70 -65~150 Unit V V Vp-p Vrms Vpeak °C W °C °C ELECTRICAL CHARACTERISTICS (Un less o the rwise spe cified : Ta= 25 °C, Vcc= 4V, fo=10. 7MHz , fm= 1 kHz, ∆ f=±3kHz ) Characteristics Squelch Current Audio Ou tpu t Vo ltag e Inp ut Limitin g Vo lta ge Total Harmonic Distortion Detector Output Voltag e Drop Voltage A F Ga in Loss Detector Output Resistance Filter Gain Filter Output DC Voltag e Mute Low Resistance Mute High Res...
