Data Sheet

5 Port 10/100 Ethernet Integrated Switch

Features

General Description

IP175A PCB compatible (pins compatible)

IP175C/IP175CH integrates a 6-port switch

Built in 6 MAC and 5 PHY

controller, SSRAM, and 5 10/100 Ethernet

Each port can be configured to be 10Base-T, transceivers. Each of the transceivers complies with

100Base-TX

the IEEE802.3, IEEE802.3u, and IEEE802.3x

2k MAC address

specifications. The DSP approach is utilized for

384k bits packet buffer memory

designing transceivers with 0.18um technology; they

Support auto-polarity for 10Mbps

have high noise immunity and robust performance.

Filter/ forward reserved address option

Broadcast storm protection

IP175C/IP175CH operates in store and forward

Auto MDI-MDIX

mode. It supports flow control, auto MDI/MDI-X,

Support three MII/RMII ports

CoS, port base VLAN, bandwidth control, DiffServ,

Support SMI with MDC up to 12.5 Mhz

SMART MAC and LED functions, etc. Each port can

Support tagging & un-tagging

be configured to auto-negotiation or forced

Support Port base VLAN & tag VLAN

10M/100M, full/half duplexmode. Using an

Support CoS

EEPROM or pull up/down resistors on specified pins

Support port security option

can configure the desired options.

Support SMART MAC function

Support spanning tree protocol

Besides

5-port

switch

application,

Max packet length 1552/ 1536 bytes

IP175C/IP175CH supports three MII/RMII ports for

Support 8-level bandwidth control

router application, which supports 4 LAN ports, one

Support Link quality LED for 100Mbps

WAN port and one HOME/PNA or Access point. The

Support direct, serial and dual color mode LED external MAC can monitor or configure

Support one fiber port with far end fault function IP175C/IP175CH by accessing MII registers through

for

IP175CH

only

SMI0.

Built in linear regulator control circuit

Low power consumption

MII/RMII port also can be configured to be MAC

0.18um, 128-pin PQFP

mode. It is used to interface an external PHY to

Support Lead Free package (Please refer to the work as a 5+1 switch. Through SMI1

Order Information)

IP175C/IP175CH can monitor and configure

external PHY.

Note – some features need CPU support, please
