This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...

RF synthesis is a critical function in today's electronic communications systems. Two of the technologies used for RF synthesis are phase locked loop (PLL) and direct digital synthesis (DDS). Each has ...

This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...
