2.0 General Description
IP101 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, IP101 provides a hardware interrupt pin
to indicate the link, speed and duplex status change.
IP101 also provides Media Independent Interface (MII)
/ Serial Network Interface (SNI) or Reduced Media
Independent Interface (RMII) to connect with different
types of 10/100Mb Media Access Controller (MAC).
IP101 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.
IP101 Transceiver is fabricated with advanced CMOS
technology, which the chip only requires 3.3V as
power supply and consumes very low power in the
Auto Power Saving mode. IP101 can be implemented
as Network Interface Adapter with RJ-45 for
twisted-pair connection or MAU for Fiber Connection.
It can also be easily implemented into HUB, Switch,
Router, Access Point, Advanced Communication
Riser (ACR) and Communication and Networking
Riser (CNR).
