XAUI™ TO SERIAL 10G BASE-LRM TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
Meets and exceeds industry standard
IEEE 802.3ae
IEEE802.3aq
High-performance mode supports 300m of MMF fiber.
Low-power mode supports 220m of MMF, as specified in the 802.3aq
standard.
Integrated AGC with a dynamic range of 60 mV–700 mV
Multiple interface support
4 Lane XAUI™ (3.125 Gbps)
XFP/XFI
Programmable amplitude control on 10G serial transmitter
PMD
- Serial 10.3125-Gbps CML
Receive equalization on XAUI and 10G serial interfaces
Power dissipation: < 1.5W (Low-power mode)
Core Supply: 1.0V; I/O: 3.3V
MDIO interface compliant to IEEE 802.3ae Clause 45 with extended
indirect address register access
Single reference clock input, enables use of low-cost 25-MHz crystal
or 156.25-MHz oscillator.
Integrated micro-controller, no external memory required
Support for XENPAK/X2 3.0 and XPAK MSA Optical Module
standards and the emerging SFP+ standard
Simplifies manufacturability with integrated built-in self test (BIST)
and loopback modes on the 10-G serial and XAUI interfaces.
Standard I
2
C serial interface support for external E2 and XFP.
XAUI link synchronization/deskew
XGXS 8B/10B error detection ENDEC
PCS 64B/66B scrambler/descrambler
• Reference clock output for XFP module reference clock
• Loss-of-signal detection
• Link activity indicator outputs
• XAUI transmit pre-emphasis for transmission over backplanes
APPLICATIONS
