IP101GRR/IP101GA/IP101GRI

The IP101G is an IEEE 802.3/802.3u compliant single port Fast Ethernet transceiver capable of simultaneous 100Mbps and 10Mbps operation. It supports Auto MDI/MDIX function to simplify network installation and reduce system maintenance cost. To improve system performance, the IP101G provides a hardware interrupt pin to indicate link, speed and duplex status changes. IP101G provides Media Independent Interface (MII) or Reduced Media Independent Interface (RMII) to interface with different types of 10/100Mbps Media Access Controllers (MAC).

The IP101G is designed to use Category 5 unshielded twisted pair cable or fiber optic cable connected to other LAN equipment. Supports connection with external 100Base-FX optical transceiver using PECL interface. With good performance, reliability, rich power saving methods and extremely low operating current, the IP101G provides system designers with a serial tool to easily complete their projects. They are system debug assistant tools and EMI management tools.

Manufactured in advanced CMOS (85nm) technology, the IP101G is designed based on IC Plus' fifth Ethernet PHY architecture, a feature that enables the IP101G to consume very low power. For example in full load operation (100Mbps_FDX) it consumes less than 0.15W.

IP101GA/IP101GR & IP101GRI are available in 48LQFP/32QFN lead-free packages.
