Description

BU2374FV is a VCO+phase comparator IC used to construct PLL system. PLL system is constructed and low jitter clocks can be generated by adopting external LPF and divider. Through a mechanism incorporated in this IC BU2374FV the output could be switched into quarter. Another function can set in the center point of frequency by  adjusting external resistance.
