NTE1657

NTE1657 Integrated Circuit Phase Lock Loop (PLL) FM Stereo Multiplex Description: The NTE1657 is a PLL FM stereo multiplex integrated circuit in a 9–Lead SIP type package suitable for automotive applications and portable radio applications because of space merit by the package and wide supply voltage range. Features: D Excellent Pilot Lamp Sensitivity: VL(ON) = 9mVrms (Typ) D Suitable for LED Driving: ILAMP = 20mA (Max) D Recommended Input Voltage Range: VIN = 200 to 500mVrms D Operating Supply Voltage Range: VCC = 3.5 to 12V D Excellent Channel Separation Through Entire Audio Frequency Range: Sep = 45dB (Typ) D Low Distortion: THD = 0.08% (Typ) @ VIN = 200mVrms (Stereo) D VCO Stop Capability (The VCO is stopped when the pin 7 is connected with the power supply line and then the stereo indicator is turn off). D Easy Adjustment (The monitored free running frequency of VCO is 38kHz @ Pin6).
