TC5081P PLL Phase-Locked-Loop
Description:
The TC5081P is an integrated circuit in a 9-Lead SIP type package consisting of a digital phase comparator and an amplifier. Three state outputs 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 thses can be utilized as lock indicator.
