VSC8489-01
Dual Channel WAN/LAN/Backplane RXAUI/XAUI to SFP+/KR 10 GbE SerDes PHY
Microsemi's full dual channel SerDes PHY provides hardware-based KR
support for timing-critical applications, including all industry-standard
protocol encapsulations.
The VSC8489-01 device meets the SFP+ SR/LR/ER/220MMF host
requirements in accordance with the SFF-8431 specifications. It also
compensates for optical impairments in SFP+ applications, along with
degradations of the PCB.
The VSC8489-01 device provides 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 VSC8489-01 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.
