Main part of the D3607 NIC Card is the BCM57762 LAN Controller. The controller settings and MAC
Address required for operation are stored in the SPI Flash as well as the PXE code.
The BCM57762 uses a 25 MHz Crystal as reference for the generation of the LAN Signals, which are
transmitted through the transformer module integrated in the RJ45 Connector. For the operation of
the PCI Express Interface is a 100 MHz Clock required, which is provided over the PCI Express Slot.
