IP175C/IP175CH
integrates
a
6-port
switch
controller,
SSRAM,
and
5
10/100
Ethernet
transceivers. Each of the transceivers complies with
the
IEEE802.3,
IEEE802.3u,
and
IEEE802.3x
specifications. The DSP approach is utilized for
designing transceivers with 0.18um technology; they
have high noise immunity and robust performance.
IP175C/IP175CH operates in store and forward
mode. It supports flow control, auto MDI/MDI-X,
CoS, port base VLAN, bandwidth control, DiffServ,
SMART MAC and LED functions, etc. Each port can
be
configured
to
auto-negotiation
or
forced
10M/100M,
full/half
duplexmode.
Using
an
EEPROM or pull up/down resistors on specified pins
can configure the desired options.
Besides
a
5-port
switch
application,
IP175C/IP175CH supports three MII/RMII ports for
router application, which supports 4 LAN ports, one
WAN port and one HOME/PNA or Access point. The
external
MAC
can
monitor
or
configure
IP175C/IP175CH by accessing MII registers through
SMI0.
MII/RMII port also can be configured to be MAC
mode. It is used to interface an external PHY to
work
as
a
5+1
switch.
Through
SMI1
IP175C/IP175CH
can
monitor
and
configure
external PHY.
IP175CH supports one fiber port with far end fault
function
