Card Power Management
The CPLD on the SharpMedia PCIE-8120 fulfills the functionality of a power management
controller for the card. The power-up and power-down control is based on the input signals.
Internal power good status, that is, 3.3V from PCIE slot is present and the device has
started properly.
VP12_FAIL signal indicating when the 12V main supply is not within the allowed range.
PERST# signal from PCIE connector indicating the system preparing to go into operation
or leaving operational mode.
VPx_PWRGD status signals of the on board DC/DC units.
Based on the status of the input signals, the following control signals display output:
VPx_PWREN enables/disables the DC/DC units according to power-up/down timing
sequence requirements.
–
Default power-up/down sequence is simultaneous.
PWRDN_VP discharges the residual voltage levels after powering off the DC/DC units.

Interfaces and S/W control
B.8.2.1
MDIO
The MDIO[1] channel from the second SerDes port of the NIC is connected to the CPLD for
basic S/W access via mapped pseudo-PHY registers. A card specific enhanced network card
driver is necessary to make use of the functionality that is provided through the CPLD. For more
