NTE980

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: 70µW (Typ) @ VCO fo = 10kHz, VDD = 5V D Operating Frequency Range up to 1.4MHz (Typ) @ VDD = 10V, RI = 5kΩ 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.
