BCM5719A1KFBG

Built on proven architecture, the BCM5719 provides a PCI Express v2.0-compliant host interface, which can operate at 5 GT/s or at 2.5 GT/s at x4 link width. The PCI Express supports MSI and MSI-X capabilities and Function Level Reset (FLR).The host interface supports a separate PCI Express function for each LAN interface. The BCM5719 includes I/O Virtualization (IOV) features such as 17 receive and 16 transmit queues, 17 MSI-X vectors with flexible vector-to-queue association. These IOV features enable the BCM5719 to support the VMWare NetQueue and Microsoft VMQ technologies. The BCM5719 includes a comprehensive set of hardware features that the system may use to implement IEEE 1588- or IEEE 802.1AS-based time synchronization. These hardware features include a high-precision clock, timestamp registers for receive/transmit packets, and programmable trigger inputs and watchdog outputs.The BCM5719 is fabricated in a low-voltage 65 nm CMOS process and integrates an efficient switching voltage regulator controller for core power supplies. Advanced power management features built into the BCM5719 enable minimizing the power consumption of the network controller subsystem by lowering the controller's power consumption under lighter network traffic without compromising performance. The BCM5719 implements Energy Efficient Ethernet (EEE) compliance with the IEEE Std 802.3az-2010, which further reduces the power consumption with idle 100 Mbit or 1 Gbit GPHY links. These features provide a low system power consumption Ethernet network interface controller solution.
