CGIC (Clock Generators ICs)

All required system clocks are included Clock Generators ICs BU7335MWV

The BU7335MWV clock generator utilizes ROHM's original high frequency accuracy PLL technology (patented) along with SS (Spread Spectrum) technology as a countermeasure against EMI, resulting in a single-chip clock system optimized for Intel® Atom™ E600 platforms. All required clocks, including those for the CPU (3 lines), PCIe, SATA, graphics (1 line), and USB are included. Designed for use with the BD9591AMWV/BD9594AMWV for sequence control.

  • All clocks required for a 5ch PLL system are integrated on a single chip, including a CK505-compliant low-jitter type.
  • Spread Spectrum function built in for reduced EMI noise.
  • Combining with a BD9594AMWV/BD9591AMWV PMIC provides additional platform support.
