| 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: D Very Low Power Consumption: 70W (Typ) @ VCO fo = 10kHz, VDD = 5V D Operating Frequency Range up to 1.4MHz (Typ) @ VDD = 10V, RI = 5k D Low Frequency Drift: 0.04%/C (Typ) @ VDD = 10V D Choice of Two Phase Comparators: Exclusive-OR Network (I) Edge-Controlled Memory Network w/Phase-Pulse Output for Lock Indication (II) D High VCO Linearity: < 1% (Typ) @ VDD = 10V D VCO Inhibit Control for ON-OFF Keying and Ultra-Low Standby Power Consumption D Source-Follower Output of VCO Control Input (Demod. Output) D Zener Diode to Assist Supply Regulation D Standardized, Symmetrical Output Characteristics D 100% Tested for Quiescent Current at 20V D 5V, 10V, and 15V Parametric Ratings Applications: D FM Demodulator and Modulator D Frequency Synthesis and Multiplication D Frequency Discriminator D Signal Conditioning D D D D FSK - Modems Data Synchronization Voltage-to-Frequency Conversion Tone Decoding Absolute Maximum Ratings: DC Supply Voltage Range (Voltages referenced to VSS terminal), VDD . . . . . . . . . . . . -0.5 to +20V Input Voltage Range, All Inputs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 to VDD+0.5V DC Input Current, Any One Input . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10mA Power Dissipation (TA = -40 to +60C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW TA = +60 to +85C . . . . . . . . . . . . . . . . . . . . . . . . . . . .
