MM4080B6-12G User Manual 4.MXM Connector Figure 4.1 MXM Connector (Card Top) Figure 4.2 MXM Connector (Card Bottom) 5.Power Group Table 5.1 shows the MXM module power requirements. The voltage tolerances in the table are specified as measured on module edge finger. The system must be able to supply the full specified current on rails (except PWR_SRC) at all times. Th current capability of the PWR_SRC rail must be defined by the system in the MXM system information structure. Table 5.1 MXM Power Rails Signal Name Note: PWR_SRC voltage range is assumed to be DC or RMS. However under any...

MM4080B6-12G User Manual 6.Power Sequencing There is no power sequencing requirement for the input voltages to the MXM module. However the PWR_EN signal may be asserted only after all power rails are within specified tolerance. The state of PWR_GOOD is undefined until all rails are fully ramped. Refer to Figure 6.1 for details Figure 6.1 Power Sequencing 7.Module Power Down and Power Up The MXM module may be powered down using the PWR_EN signal. The system designer may choose to shut down or keep the input power while the module is powered down. Refer to Figure 7.1 for details. Figure 7.1...

MM4080B6-12G User Manual 8.Reset Requirements System reset may be deasserted only after the assertion of the PWR_GOOD signal. Figure 8.1 shows the reset requirements relative to the PWR_EN and PWR_GOOD signals. This sequence must be followed on initial power on, system reset and resume from suspend/hibernate. Figure 8.1 Reset Sequencing 9.DisplayPort Interface DC blocking capacitors of DisplayPort must be placed on the system board. In addition to the MXM implementation of Dual-mode DisplayPort requires the circuit in Figure 9.1 on the AUX lines for proper dongle detection. The HPD signal...

MM4080B6-12G User Manual 10.DVI/HDMI on DP Interface Native DVI or HDMI connector support can be implemented using a DisplayPort interface. Additional circuitry is required on the system and the proper signal mapping must be observed. As Figure 10.1 shows, 499Ω 1% pull-down resistors to ground on the DP lane signals must be placed on the con1ector side of AC coupling capacitors gated by a FET to limit the leakage. Additionally level shifting circuits must also be implemented on DDC Data and Clock. Table 10.1 shows the mapping to connect the signals from the MXM connector to the HDMI/DVI...

Cooling Suggestion: 1、显卡建议先固定在散热器上，散热器外径为 4mm，M2 的螺柱。 2、散热器的重量要用箱体来支撑固定。 3、显存和 MOS 要加导热垫。 Components Mosfet *显存和 MOS 由“探针”监测；GPU 由“Furmark
