AVB交换机 88E6240 Link Street ® 88E6240 Datasheet 4 FE + 3 GE AVB Switch with Energy Efficient Ethernet (EEE) The Marvell ® 88E6240 device is a single-chip integration of a 7-port Ethernet switchwith four integrated Fast Ethernet transceivers, and one integrated Gigabit Ethernet transceiver. This device supports the latest IEEE 802.1 Audio Video Bridging (AVB) standards. The device uses these AVB technologies to identify and reserve network resources for AVB traffic streams and supports precise isochronous streaming capability. These AVB protocols enable timing sensitive multimedia streams (such as digital video,audio, or industrial control traffic) to be sent over an Ethernet network with low latency and robust Quality of Service guarantees.
