"VSC8484 is a quad channel XAUI-to-serial transceiver that delivers minimum cost per channel with maximum port densities at the lowest power. The device achieves an excellent 1 W per channel power dissipation while supporting the increased port densities required for next-generation 10G platforms. VSC8484 integrates Microsemi's world-class electronic dispersion compensation (EDC) performance across multiple data rates: 9.95G WAN, 10.3 Gigabit Ethernet (GE), and 10.5G Fibre Channel. The device also meets the SFP+ SR/LR/LRM host requirements in accordance with the SFF-8431 and IEEE 802.3aq specifications. The EDC capabilities are optimized by the VScope™ input signal monitoring integrated circuit, which delivers more accurate, in-line views of the post-equalization waveform. VSC8484 compensates for optical impairments in SFP+ LRM applications, along with degradations of the PCB, while providing wide system margin for SR and LR applications. The transmit path incorporates a multi-tap output driver to provide the flexibility required to meet the demanding 10GBASE-KR IEEE 802.3ap standard."
