Product Summary

The OZ9939GN is a Smart Multi-DIMM Selector. The OZ9939GN supports the switching between a primary SMBus and 3 other secondary SMBus. This function is particularly useful for DIMM devices and the support of PAS (Preboot Authentication Service). In addition, the OZ9939GN can be configured to support two different power planes with different sets of General Purpose Input/Output (GPIO) signals, which supplements and enhances the power management capability of the chipsets, commonly found in an ACPI (Advanced Configuration of Power Interface) subsystem.
