Product Summary
The WG82574L is a single, compact, low power component that offers a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) port. The WG82574L uses the PCI Express* (PCIe*) architecture and provides a single-port implementation in a relatively small area so it can be used for server and client configurations as a LAN on Motherboard (LOM) design. The WG82574L can also be used in embedded applications such as switch add-on cards and network appliances.
Parametrics
WG82574L absolute maximum ratings: (1)VCBO: 20 V dc; (2)VCEO: 20 V dc; (3)IC(max): 1 A; (4)IC(peak): 1.2 A; (5)Ptot Minimum total dissipated power @ 25℃ ambient temperature: 1.5 W; (6)hFE DC current gain @ Vce=-10 V dc, Ic=500 mA: 85; (7)hfe AC current gain @ Ic=50mA VCE=-10 V dc, f=20 MHz: 2.5; (8)Cc collector capacitance @ VCB=-5V, f=1MHz: 50 pF; (9)fT Transition frequency @ Ic=10mA, VCE=-5 V dc, f=100 MHz: 40 MHz.
Features
WG82574L features: (1)using more than 4 GB of physical memory; (2)Programmable host memory receive buffers (256 bytes to 16 KB); (3)Intelligent interrupt generation features to enhance driver performance; (4)Descriptor ring management hardware for transmit and receive software controlled reset(resets everything except the configuration space); (5)Message Signaled Interrupts (MSI and MSI-X); (6)Configurable receive and transmit data FIFO, programmable in 1 KB increments.
