X299 Designare EX Circuit Analysis Continued
The audio hardware isn't that crazy; it is a simple Realtek ALC1220 with WIMA film capacitors and Nippon Chemicon audio capacitors.
GIGABYTE used both Intel's i219v PHY and Intel i211AT, which provide two Intel Gbit NICs.
The WIFI controller is the Intel Wireless-AC 8265NGW, which is very common on high-end systems. We find one ASMedia ASM3142, which is used as a USB 3.1 controller for the type-C internal header.
We also found Intel's new JHL6540 ThunderBolt 3 controller, which outputs two type-C Thunderbolt 3 ports. For correct handling and power delivery of the type-C ports two Texas Instruments TPS65982 controllers are used. However we also need power for those ports, and that's where two ON Semiconductor NCP3235 15A high current buck converters.
The Realtek RTS5411 chip is a USB 3.0 hub, and takes one USB 3.0 port and outputs four. An ASMedia ASM1061 produces two extra SATA6Gb/s ports for a total of eight.
The NXP DBTL08GP053 multi-output/input 10Gb/s PCI-E switch is used for switching around all the different bandwidth around the PCI-E slots and M.2 slot. An ICS6V41742A clock generator enhances BCLK overclocking.
The main SuperIO is an IT8686E, which controls system management functions like monitoring, and provides PS/2 for the rear IO. An IT8795E expands fan control and temperature monitoring.
An ITE IT8951 is used to provide BIOS recovery through a USB drive; they call it Q-Flash Plus. The IT8295FN is used as a microcontroller that provides digital RGB LED support.
