• Simultaneous LAN and WAN support

• RXAUI/XAUI support

• SFP+ I/O with KR support

• 1 GbE support

• Seamless upgrade path for IEEE 1588v2

and MACsec functionality

Applications

• Multiple-port RXAUI/XAUI to SFI/ SFP+ line

cards or NICs

transceivers

• Secure data center to data center

interconnects

• 10 GbE switch cards and router cards

Microsemi's full dual channel SerDes PHY provides hardware-based KR

support for timing-critical applications, including all industry-standard

protocol encapsulations.

The VSC8489 device meets the SFP+ SR/LR/ER/220MMF host

requirements in accordance with the SFF-8431 speciﬁ cations. It also

compensates for optical impairments in SFP+ applications, along with

degradations of the PCB.

The VSC8489 device provides full KR support, including KR state

machine, for autonegotiation and link optimization. The transmit

path incorporates a multitap output driver to provide ﬂ exibility to

meet the demanding 10GBASE-KR (IEEE 802.3ap) Tx output launch

requirements.

Highly ﬂ exible clocking options enable Layer 1 support for Synchronous

Ethernet. The VSC8489 device uses a single 156.25 MHz reference

clock for LAN/WAN operation. It includes a failover switching capability

for protection routing, along with selectable lane ordering. A complete

suite of BIST functionality includes line and client loopbacks along with

pattern generation and error detection.
