VSC8479 Gbps to Gbps 16-bit Transceiver 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 Gbps to 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 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. The receiver path has a high sensitivity receiver with a programmable VGA and input bandwidth equalization EQ to provide stressed input data eye compensation. No external post is required for most applications. The high-speed output is swing and pre-emphasis programmable to support a variety laser driver and XFI host ASIC applications. The VSC8479 fully supports all features, functions and clock modes required for 300-pin multi-source agreement MSA transponder module full compliance. All loopback modes are supported with multiple line timing clock modes. A highly reference clock source selection and reference clock clean-up support scheme is provided to minimize external circuitry. A selectable two-wire serial or Serial Peripheral Interface SPI provides full microcontroller access to all status and control registers, including software read-back capability of all external control input pins. Any combination of discrete pins and serial register status and control can be employed. A highly PRBS and user pattern checker and error count provides system analysis and built-in selftesting. Robust cross talk immunity enables the VSC8479 to operate the Tx and Rx paths asynchronously to each other while exceeding SONET level jitter generation and jitter tolerance performance. A high-speed output clock can be optionally enabled for higher performance applications.
