Wide band 3Ghz-6GHz integer phase-locked loop

Overview

065TSMC_PLL_08 is an integer-N phase-locked loop frequency synthesizer (PLL) based on fully integrated wide band LC-VCO with range from 3 GHz to 6 GHz with good phase noise performance. It works with
reference frequency from 25 MHz XTAL oscillator or external signal source with frequency up to 500 MHz. Phase-frequency divider compare frequency can be equal or 2,3,4...63 times lower than reference. VCO frequency N-divider has programmable coefficient of division with step 1 in range 4 to 2047. Phase-frequency detector has built-in analog and digital lock detector circuits. Charge pump scheme with ADC and adjustable output current allow compensation VCO gain variation within band and keep loop gain constant. Integrated low-pass loop filter has adjustable values of resistance and capacitance for tune loop and get best phase-noise performance.
The PLL is designed using TSMC 65 nm CRN65LP technology.
