VSC8489-10 and VSC8489-13  
Dual Channel WAN/LAN/Backplane  
RXAUI/XAUI to SFP+/KR 10 GbE SerDes PHY  
with VeriTime™  
Highlights  
• IEEE 1588v2 compliant  
• Failover switching and lane ordering  
• Simultaneous LAN and WAN support  
• RXAUI/XAUI support  
Vitesse’s dual channel SerDes PHY provides fully  
IEEE 1588v2-compliant devices and hardware-based KR  
support for timing-critical applications, including all  
industry-standard protocol encapsulations.  
• SFP+ I/O with KR support  
• 1 GbE support  
VeriTime™ is Vitesse’s patent-pending distributed timing technology  
that delivers the industry’s most accurate IEEE 1588v2 timing  
implementation. IEEE 1588v2 timing integrated in the PHY is the  
quickest, lowest cost method of implementing the timing accuracy that  
is critical to maintaining existing timing-critical capabilities during the  
migration from TDM to packet-based architectures.  
Applications  
• Multiple-port RXAUI/XAUI to  
SFI/ SFP+ line cards or NICs  
• 10GBASE-KR compliant backplane  
transceivers  
The VSC8489-10 and VSC8489-13 devices support 1-step and 2-step  
PTP frames for ordinary clock, boundary clock, and transparent clock  
applications, along with complete Y.1731 OAM performance  
monitoring capabilities.  
• Carrier Ethernet networks requiring  
IEEE 1588v2 timing  
• Secure data center to data center  
interconnects  
The devices meet the SFP+ SR/LR/ER/220MMF host requirements in  
accordance with the SFF-8431 specifications. They also compensate  
for optical impairments in SFP+ applications, along with degradations  
of the PCB.  
• 10 GbE switch cards and router cards  
The devices provide full KR support, including KR state machine, for autonegotiation and link optimization. The  
transmit path incorporates a multitap output driver to provide flexibility to meet the demanding 10GBASE-KR  
(IEEE 802.3ap) Tx output launch requirements.  
Highly flexible clocking options enable Layer 1 support for Synchronous Ethernet. The devices use a single  
156.25 MHz reference clock for LAN/WAN operation. They include 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.
