NTE1208
Integrated Circuit
CMOS, Phase Comparator
Description:
The NTE1208 is an integrated circuit in a 9鈥揕ead SIP type package consisting of a digital phase
comparator and an amplifier. Three state output connected to low pass filter (using an internal amplifi-
er) will produce DC voltage to control a VCO.
Low state pulses appear on phase out as long as the loop is unlocked and these can be utilized as
lock indicator.
