The ll_pll2651s01_ln28lpp_7002 is a 1.8V/1.0V dual supply-voltage phase locked loop (PLL) with a wide-output-frequency-range for frequency synthesis. It consists of a phase frequency detector (PFD), a charge pump, a voltage-controlled oscillator (VCO), a 6-bit pre-divider, a 9-bit main-divider, a 3-bit scaler, a delta-sigma modulator (DSM) and an automatic frequency control (AFC).
