IP179N/NI/H/HI数据手册IC+中文资料规格书

描述 Description

The IP179N/H is a professional high-end SoC targeted for the Ethernet switch (w/ or w/o POE chips) or NVR application. This SoC is built in with an advanced switch engine, aiming to provide high-quality imagery output. Other built-in IPs, included a low power 9-port fast Ethernet transceivers, SSRAM, regulator, ESD protection and etc.
 The built-in transceivers, all comply with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. These transceivers were designed under DSP approach and produced with 85nm technology, hence the high noise immunity and robust performance. The switch controller of IP179N/H is designed to operate under store and forward mode.
 It supports up to 2K MAC addresses. These tables are accessible through MII register. The address table can configure either “2K unicast addresses” or “1K unicast addresses and 1K multicast addresses“. Rich control and management features supported, included IEEE 802.1Q, IGMP Snooping, QoS and etc.
 As an advanced Ethernet Switch controller, IP179N/H supports 2 operation modes to serve different application requirements precisely, Normal mode (Best quality for the down/up-load stream both) and IPC mode (Best efforts for the upload stream data).
 Besides this, considering the distance problem that could be generated while installing a far away (> 100meters) IP CAM to link with the Switch device. IP179N/H supports the LBAS function to handle/fix this situation.
 All of the functions that describe above, an external MAC/CPU can monitor or configure them by accessing MII registers through MDC/MDIO that IP179N/H supported.
