The Phase Locked Loop (PLL) for clock recovery used in a single chip 155. 52 Mb/s4-Ch CMOS LSI (QPLC) for SONET/SDH termination is described in this letter. This LSI is the first quad-channel ATM physical layer controller chip in which each channel has a clock recovery PLL achieving 55ps rms jitter, using current regulated constant amplitude differential VCO and the triple well structure.
