| NTE1208 Integrated Circuit CMOS, Phase Comparator Description: The NTE1208 is an integrated circuit in a 9-Lead SIP type package consisting of a digital phase comparator and an amplifier. Three state output connected to low pass filter (using an internal amplifier) 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.
