IP101G is an IEEE 802.3/802.3u compliant
single-port Fast Ethernet Transceiver for both
100Mbps and 10Mbps operations. It supports
Auto MDI/MDIX function to simplify the network
installation and reduce the system maintenance
cost. To improve the system performance,
IP101G provides a hardware interrupt pin to
indicate the link, speed and duplex status
change. IP101G provides Media Independent
Interface (MII) or Reduced Media Independent
Interface (RMII) to connect with different types
of 10/100Mbps Media Access Controller (MAC).
IP101G is designed to use category 5
unshielded twisted-pair cable or Fiber-Optic
cables connecting to other LAN devices. A
PECL interface is supported to connect with an
external 100Base-FX fiber optical transceiver.
Except good performance, reliability, rich power
saving method and extreme low operating
current, IP101G provides a serial tool for
system designers to complete their projects
easily. They are System Debug Assistant Tool
and EMI Management Tool.
IP101G is fabricated with advanced CMOS
(85nm) technology and design is based on
IC Plus’s 5th Ethernet-PHY architecture, this
feature makes IP101G consumes very low
power. Such as in the full load operation
(100Mbps_FDX), it only takes below 0.15W.
IP101GA / IP101GR&IP101GRI are available in
48LQFP/32QFN, lead-free package.
