BLOCK DIAGRAM:

APPLICA TIONS:

LOW POWER:

Exceptionally low power (700 mW LAN mode or 750 mW WAN mode) allows for higher port

densities

WIDE RANGE OF SUPPORT:

Fully com

patible with IEEE 802.3ae and T11 10 GFC

Extended-WIS (E-WIS) provides full Clause 50 support and enables transport over existing

SONET networks

10 Gbps serial interface exceeds all SONET and 10 GbE requirements

4 x 3.125 Gbps and 3.182 Gbps XAUI I/O enable interconnection with a wide range of Layer-2

devices

Seamless connectivity to XFP and SFP+ modules

10 Gbps receiver exceeds all 10 GbE stressed eye requirements

T OOLS FOR RAPID DESIGN:

Multiple loopback modes and built-in self test (BIST) capabilities reduce system development

costs, enable manufacturing tests, and improve time to market

JTAG access port facilitates boundary scan for in-circuit test to improve board yield

Single 1.2 voltage for the whole chip with optional power supply range (1.2 V, 1.8 V, and 3.3 V)

for the TTL interface

FLEXIBILITY :

XAUI I/O programmability for lane swap, invert, amplitude, pre-emphasis, and equalization

KX4-compatible 3 Gbps I/O for long-reach copper interconnect provides additional margin to

traverse connectors and the backplane up to 40 inches

Extended-PCS (E-PCS) mode with forward error correction (FEC) auto-negotiation allows

extended reach over single-mode and multimode fiber with 10–15 error floor

Enhanced de-emphasis and equalization compensates for connector and channel losses and

makes the device SFP+ compatible

Accessibility of the recovered clock from high speed input and separate clock paths for CMU

and CRU enable Layer 1 support for Synchronous Ethernet

XGMII interface enables the device to be used in a roll-over redundant link application to

provide fault tolerance

10 Gbps Ethernet LAN/WAN switches, routers,

and router to WAN interconnects

10 Gbps Ethernet network interface cards

10 Gbps Fibre Channel host bus adapters and

switches

SPECIFICA TIONS:

Total power: 750 mW

Supply voltage: 1.2 V
