Overview
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.
Key features
- AMS BiCMOS 0.35 um
- Ability to work with VCOs with both positive and negative frequency dependence of the control voltage
- Input frequencies up to 100 MHz
- Differential CMOS output signal
- CMOS output signal for lock detector
- Built-in reset delay circuit
- Portable to other technologies (upon request)
