Z270X-UD5 Circuit Analysis Continued




GIGABYTE's ALC1220 implementation relies on the new integrated headphone amplifier for the 120dB SNR output. They also use Nichicon audio capacitors to improve audio quality and divide the audio section of the PCB from the rest of the motherboard. There are six LEDs located in the audio section; they are yellow.





Intel's USB3.1/ThunderBolt 3 controller, the JHL6540 is used along with a Texas Instruments TPS65982 as the type-C switch and USB Power Delivery 2.0 controller. The motherboard's USB Power Delivery system offers up to 36W output. The motherboard has two Intel NICs, the i219v PHY to compliment the integrated MAC in the PCH, and the standalone i211AT Gbit NIC.




The main SuperIO is the ITE IT8686E and provides some fan control and system functions. The ITE IT8792E embedded controller helps improve fan control capabilities. The motherboard has two 128Mbit (16MB) ROMS from Macronix.




Two Texas Instruments GD75232 driver and receiver chips support the two COM internal headers. Multiple ASMedia ASM1480s switch PCI-E bandwidth between the PCI-E slots.




An ASMedia ASM1442K level shifter provides the HDMI port on the rear IO panel.
