BU2394KN/BU2396KN is a single-chip clock generator with a built-in PLL that generates CCD, USB and VIDEO clocks for digital cameras. It features small packaging, simplified clock systems, and reduces the number of components used in mobile camera equipment.
The BU2394KN and BU2396KN are three‑channel PLL clock generator ICs designed for digital still and video camera applications. They generate CCD, USB and VIDEO clocks from a crystal oscillator, simplifying the clock architecture of mobile camera equipment.
Key features include a single 3.3 V supply, compact VQFN‑20 package, low period‑jitter outputs, and selectable reference input frequencies (14.318182 MHz or 12 MHz). The devices operate from –5 °C to +70 °C and provide a range of output frequencies for CCD (135 MHz‑98 MHz), USB (48 MHz), and VIDEO clocks.
