speeds of operation
Dual interconnect between the Media
Access Controller (MAC)2 and Physical
Layer (PHY):
— PCIe-based interface for active state
operation (S0 state)
— Automatic polarity correction
— SMBus for host and management traffic (Sx
low power state)
Technology
— IEEE 802.3u auto-negotiation conformance
— MDC/MDIO management interface
— Flexible filters in PHY to reduce MAC power
— Shared NVM access through the MAC
— 48-pin package, 6 x 6 mm with a 0.4 mm
lead pitch and an Exposed Pad* for ground
— MACSec hardware ready (802.1AE), Intel®
VPro, Intel® Viiv and Virtualization support
with appropriate Intel® chipset(s)
components
— Three configurable LED outputs
— Flexible power configuration: use either the
Intel® 5 Series Express Chipset 1.05 Vdc
shared voltage rail or the fully integrated
82577 1.0 Vdc linear regulation
