Data Sheet

NTE980
Integrated Circuit
CMOS, Micropower Phase-Locked Loop (PLL)

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 = 5k?
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
Frequency Discriminator
Signal Conditioning
FSK - Modems
Data Synchronization
Voltage-to-Frequency Conversion
Tone Decoding
