The D-Link DFE-530TX+ is made possible by the Realtek RTL8139A single-chip Fast Ethernet controller. The Realtek RTL8139A is a highly integrated and cost-effective single-chip Fast Ethernet controller that provides 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-T specifications and IEEE 802.3x Full Duplex Flow Control. It also supports ACPI, PCI power management for modern operating systems that is capable of Operating System Directed Power Management (OSPM) to achieve the most efficient power management. The D-Link DFE-530TX+ includes two independent 2 Kbyte receive and transmit FIFO's (First in First out) buffers to improve memory transfer efficiency, an integrated N-Way auto-negotiating transceiver, and a Wake-up on LAN (WOL) capability. The board includes a WOL connector and cable. The DFE-530TX+ represents a low-cost Ethernet adapter suitable for PCs, high-end workstations, and workgroup file servers.
