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: V_L(ON) = 9mV_rms (Typ)
D Suitable for LED Driving: I_LAMP = 20mA (Max)
D Recommended Input Voltage Range: V_IN = 200 to 500mV_rms
D Operating Supply Voltage Range: V_CC = 3.5 to 12V
D Excellent Channel Separation Through Entire Audio Frequency Range: Sep = 45dB (Typ)
D Low Distortion: THD = 0.08% (Typ) @ V_IN = 200mV_rms (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).
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
