Description:

The NTE980 CMOS Micropower Phase–Locked Loop (PLL) consists of a low–power, linear voltage–controlled oscillator (VCO) and two different phase comparators having a common signal–input amplifier and a common comparator input in a 16–Lead type package. A 5.2V zener diode is provided for supply regulation if necessary.

Features:

● Very Low Power Consumption: 70µW (Typ) @ VCO fo = 10kHz, VDD = 5V

● Operating Frequency Range up to 1.4MHz (Typ) @ VDD = 10V, RI = 5kΩ

● Low Frequency Drift: 0.04/°C (Typ) @ VDD = 10V

● Choice of Two Phase Comparators:

Exclusive–OR Network (I)

Edge–Controlled Memory Network w/Phase–Pulse Output for Lock Indication (II)

● High VCO Linearity: < 1 (Typ) @ VDD = 10V

● VCO Inhibit Control for ON–OFF Keying and Ultra–Low Standby Power Consumption

● Source–Follower Output of VCO Control Input (Demod. Output)

● Zener Diode to Assist Supply Regulation

● Standardized, Symmetrical Output Characteristics

● 100 Tested for Quiescent Current at 20V

● 5V, 10V, and 15V Parametric Ratings

Applications:

● FM Demodulator and Modulator

● Frequency Synthesis and Multiplication
