50MHz to 800MHz Integer-N RC Phase-Locked Loop on SMIC 55nm LL
055SMIC_PLL_01 forms clock output signal with frequency from 50 to 800MHz.
Overview
055SMIC_PLL_01 forms clock output signal with frequency from 50 to 800MHz. It consists of the ring VCO with frequency from 400 to 800MHz, a programmable feedback divider, a low noise digital phase noise detector (PFD), a precision charge pump (CP) with internal loop filter, lock detector (LD) and programmable clock divider to obtain a required output frequency. LO output signal is CMOS compatible.
Silicon area: 0.018 mm2.
