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 am-
plifier and a common comparator input in a 16–Lead type package. A 5.2V zener diode is provided
for supply regulation if necessary.
