Circuit Analysis Continued




An Intel i218v is provided as the PHY for the integrated GBit NIC. Four of the USB 3.0 ports on the backpanel are routed through a NEC/Rensas D720210 which is a 1-to-4 USB 3.0 hub.




An IDT6V49332 is a clock generator which basically helps out with BCLK overclocking. The iTE IT8792E and at least six linear regulators are used to handle the extra pins in the socket; the CPU Mode switch is hooked up to this IC which digitally enables or disables extra pins.





Dual 128Mbit (16MB) BIOS ROMs are provided along with an IT8951E which allows for the addition of USB BIOS recovery in case DualBIOS doesn't work.




The main SuperIO is an IT8620E which monitors and controls voltage, temperature, and fans. It also provides the PS/2 keyboard and mouse ports on the back. A secondary EC is used, the IT8792E, and it helps the SuperIO. Four nuvoTon NCT3941S provide voltage mode fan control of four headers. Four NXP L04083B switch two PCI-E lanes each from the first PCI-E 16x slot to the second. A single NXP L04083B switches bandwidth from the SATA Express (2 SATA ports) to the M.2 slot if needed.
