GENERAL DESCRIPTION:
The VSC8479 is a 1:16, 16:1 transceiver with integrated Clock and Data Recovery unit (CDR) and Clock Multiplier Unit (CMU) that provides the most comprehensive solution available in the industry. Continuous frequency of operation spans from 9.953 Gbps to 11.3 Gbps over full temperature range. Targeted for XFP Host ASIC SERDES, 300 pin module and DWDM line card applications, the VSC8479 provides industry leading optimization of power, performance,
programmability, price and feature integration. The 1.15 W total power dissipation enables 300 pin MSA module vendors to provide performance and functionality advantages while dropping the overall power dissipation of their existing modules. The VSC8479 is a perfect choice for XFP motherboards with proven inter-operability with all major XFP module vendors.
