BU2373FV and BU2374FV are high-performance image sampling VCOs with built-in VCO and phase comparator, which can conveniently build a PLL system through external connection of LPF and frequency divider. In order to facilitate the loop constant settings of the PLL system, the application manual has been enhanced to ensure studies on the application.
The BU2373FV and BU2374FV are general‑purpose video‑accessory VCO ICs that integrate a voltage‑controlled oscillator and a rising‑edge phase comparator. They are intended for PLL configurations in CRT, LCD monitor and CD‑RW applications, with external LPF and frequency divider connections.
The devices operate from 3.0 V to 5.0 V supply, support a selectable output frequency division, and are supplied in a compact SSOP‑B14 package. Detailed electrical characteristics, absolute maximum ratings, and reference data for voltage, temperature and oscillation ranges are provided in the note.
