BU2280FV, BU2360FV, BU2362FV are ROHM company's high-performance clock generators that integrate the 3 clock signals required for DVD players, namely VIDEO, AUDIO, and SYSTEM clocks, using PLL technology. The AUDIO clock is a DVD-Video standard and has high C/N characteristics that lower distortion.
The BU2280FV is a high‑performance clock generator IC designed for DVD‑Video, DVD‑Audio and system clocks in A/V equipment. It uses a built‑in PLL to generate multiple clock outputs from a single crystal oscillator and operates from a 3.3 V supply.
The document provides absolute maximum ratings, recommended operating ranges, detailed electrical characteristics, reference waveforms, temperature and supply‑voltage variation data, and ordering part numbers for the BU2280FV and its related parts BU2360FV and BU2362FV.
