NTE980
Integrated Circuit
CMOS, Micropower PhaseLocked Loop (PLL)
Description:
The NTE980 CMOS Micropower PhaseLocked Loop (PLL) consists of a lowpower, linear voltage
controlled oscillator (VCO) and two different phase comparators having a common signalinput am-
plifier and a common comparator input in a 16Lead type package. A 5.2V zener diode is provided
for supply regulation if necessary.
