APPL ICATIONS :
L OW POWE R :
`
Exceptionally low power (700 mW LAN mode or 750 mW WAN mode) allows for higher port
densities
WIDE R ANGE OF S UPPOR T:
`
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
`
Seamess connectivity to XFP and SFP+ modules
`
10 Gbps receiver exceeds all 10 GbE stressed eye requirements
TOOL S F OR R APID DE S IGN:
`
Multiple loopback modes and built-in self test (BIST) capabilities reduce systemdevelopment
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 IBIL ITY:
`
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 fromhigh 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
