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:
• Excellent Pilot Lamp Sensitivity: VL(ON) = 9mVrms (Typ)
• Suitable for LED Driving: ILAMP = 20mA (Max)
• Recommended Input Voltage Range: VIN = 200 to 500mVrms
• Operating Supply Voltage Range: VCC = 3.5 to 12V
• Excellent Channel Separation Through Entire Audio Frequency Range: Sep = 45dB (Typ)
• Low Distortion: THD = 0.08% (Typ) @ VIN = 200mVrms (Stereo)
• 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).
• Easy Adjustment (The monitored free running frequency of VCO is 38kHz @ Pin6).
