Abstract
This paper describes a DLL-based 150MHz-400MHz programmable clock multiplier which achieves lps-5ps RMS jitter and -70dBc reference spur level. The DLL uses a sampling phase detector and employs chopping, autozeroing and various other circuit techniques to reduce static phase offset and crosstalk between the reference and the output clock
