Technical Summary

The Quanta X12NB5/RD3 project is an Intel Cresent Bay ULT platform motherboard designed for 14", 15", and 17" chassis variants. The board is built around a Broadwell U processor in a BGA1168 package, paired with an NVIDIA N16S-GT discrete GPU in a 23x23mm package with four 256Mx16 DDR3 VRAM chips. System memory consists of two DDR3L SODIMM slots. The embedded controller is an iTE 8987 in an LQPF128 package, and the system BIOS is stored on an SPI ROM. Audio is handled by a Realtek ALC3241 codec in an MQFN package, while networking is provided by a Realtek RTL8111HSH Gigabit LAN controller in an OFN32 package. A Realtek RTS5237S-GR card reader in LQPF48 and a Realtek RTD2136 eDP level shifter in QFN-32 are also present. The 6-layer PCB stack-up includes TOP, SGND, IN1(High), IN2(Low), SVCC, and GND layers.
