LOW POWER:
Exceptionally low power (700 mW LAN mode or 750 mW WAN mode) allows for higher port
densities
W I D E R A N G E O F S U P P O R T:
Fully compatible 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
TOOLS 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
F L E X I B I L I T Y:
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
A P P L I C AT I O N S :
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
S P E C I F I C AT I O N S :
Total power: 750 mW
Supply voltage: 1.2 V
