Product Brief
Cortina Systems® IXF1104 4-Port 10/100/1000 Mbps Ethernet Media
Access Controller With System Packet Interface Level 3 (SPI-3)
Product Highlights
• Configurable on a per-port basis for 10/100/1000 Mbps Ethernet
• Includes flexible MAC, serializer/deserializer (SerDes), and Copper PHY interfaces for low cost connectivity
• Features 32 Kbytes of receive buffer and 10 Kbytes of transmit buffer for loss-less flow control of Jumbo Frames
• Flexible system interface supports 32-bit SPI-3 or 4x8-bit SPI-3 up to 133 MHz
Product Overview
The explosion of Internet Protocol (IP) traffic and the
proliferation of sophisticated applications are driving
the demand for greater network bandwidth inside and
outside the enterprise. This is pushing Ethernet to
higher speed and performance in the LAN and at the
same time extending Ethernet into new market
segments including wireless, broadband access, multi-
service switches, metro/core, and storage area
networks. This trend motivates networking equipment
suppliers to search for Ethernet building blocks that
can provide more reliable and cost-effective
communications solutions. To address this need,
Cortina Systems, Inc. (Cortina) offers the Cortina
Systems
®
IXF1104 4-Port 10/100/1000 Mbps Ethernet
Media Access Controller (MAC) with System Packet
Interface Level 3 (SPI-3) (IXF1104), a member of the
Cortina MAC family of communication building blocks.
The IXF1104 is a 4-port Gigabit Ethernet MAC that
provides an aggregate 4 Gbps system-level interface to
individual full-duplex 10/100/1000 and half-duplex
10/100 Ethernet MACs. The device features the
industry-standard System Packet Interface (SPI-3)
providing a high-performance interface to the IXP2400
network processor or to a switching ASIC.
The industry-standard Gigabit Media Independent
Interface (GMII) and Reduced Gigabit Media
Independent Interface (RGMII) provide the PHY
interface for copper connectivity. An integrated SerDes
provides a PHY interface for direct connection to optical
modules, helping reduce board real estate and system
cost.
The integrated LED controller, internal management
data input/output (MDIO) interface with auto-scan
capability, high port-count, and single CPU interface
enable the IXF1104 MAC to reduce the number of
components required for a non-blocking twisted-pair or
fiber-based Gigabit Ethernet solution. The combination
of high integration, flexibility, and loss-less flow control
capability make the IXF1104 MAC a highly cost-
effective solution for the deployment of high-speed
Ethernet capability in a variety of growing application
segments.
Product Applications
By providing a combination of MAC, SerDes, and
Copper PHY interfaces in a small footprint, the IXF1104
4-port 10/100/1000 Mbps Ethernet MAC provides a
highly integrated and flexible Ethernet building block to
help address the growing bandwidth requirements in a
wide range of applications. These include multiservice
switches, edge and MAN routers, DSLAMs, cable
modem termination system (CMTS), and wireless
infrastructure equipment.
