NE565N
M51361P
General Purpose Phase Lock Loop (PLL)
The NE565N is a general purpose Phase Lock Loop (PLL) in a 14-Lead DIP type package containing a stable, highly linear voltage controlled oscillator (VCO) for low distortion FM demodulation, and a double balanced phase detector with good carrier suppression. The VCO frequency is set with an external resistor and capacitor, and a tuning range of 10:0 can be obtained with the same capacitor. The characteristics of the closed loop systembandwidth, response speed, capture and pull-in range may be adjusted over a wide range with an external resistor and capacitor. The loop may be broken between the VCO and the phase detector for insertion of a digital frequency divider to obtain frequency multiplication.
Features:
200ppm/°C Frequency Stability of the VCO
Power Supply Range of ±5V to ±12V with 100ppm/% Typical
0.2% Linearity of Demodulated Output
Linear Triangle Wave with in Phase Zero Crossings Available
TTL and DTL Compatible Phase Detector Input and Square Wave Output
Adjustable Hold in Range from ±1% to > ±60%
