S1T3361D01

LOW VOLTAGE/POWER NARROW BAND FM IF S1T3361D INTRODUCTION The S1T3361D 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. 16−DIP−300A 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 to 7.0V 16−SOP−225A APPLICATIONS Cordless phone (for home usage) FM dual conversion communications equipment ORDERING INFORMATION Device S1T3361D01-D0B0 S1T3361D01-S0B0 Package 16−DIP−300A 16−SOP−225A Operating Temperature − 20°C to +70°C 1 S1T3361D LOW VOLTAGE/POWER NARROW BAND FM IF PIN CONFIGURATION OSC 1 2 3 4 S1T3361D 5 6 7 8 16 15 14 13 12 11 10 9 RF INPUT GND OSC MIXER OUTPUT VCC LIMITER INPUT DECOUPLING MUTE SCAN CONTROL SQUELCH INPUT FILTER OUTPUT FILTER INPUT AUDIO OUTPUT DECOUPLING QUADRATURE INPUT ABSOLUTE MAXIMUM RATINGS Characteristic Max.
