UTCMC3361BP

UTC MC3361BP LINEAR INTEGRATED CIRCUIT LOW VOLTAGE/POWER NARROW BAND FM IF DESCRIPTION The UTC MC3361BP is designed for use in FM dual conversion communication. It contains a complete narrow band FM demodulation system operable to less than 2.5V 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. SOP-16 FEATURES *Low power consumption (4.0mA typ. at Vcc=4.0V) *Excellent input sensitivity (-3dB limiting, 2.0µVrms typ.) *Minimum number of external components required. *Operating Voltage:2.5~7.0V DIP-16 APPLICATIONS *Cordless phone (for home use) *FM dual conversion communications equipment PIN CONFIGURATION OSC OSC MIXER OUTPUT Vcc LIMITER INPUT DECOUPLING DECOUPLING QUADRATURE INPUT 1 2 3 4 5 6 7 8 16 15 14 RF INPUT GND MUTE SCAN 13 CONTROL 12 11 10 9 SQUELCH INPUT FILTER OUTPUT FILTER INPUT AUDIO OUTPUT UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R108-010,A UTC MC3361BP LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS(TA=25°C) PARAMETER SYMBOL VALUE UNIT Max.
