Phase-frequency detector in CMOS logic
The phase-frequency detector (PFD) consists of a signal level converter from differential reduced swing ECL to single-ended full swing CMOS signal and two D-flip-flops with reset, made in CMOS logic. Multiplexer allows to switch the input signals to the corresponding inputs.
The block is fabricated on AMS BiCMOS 0.35 um technology.
