standard that is widely used to transport standard-definition (SD) digital video in the broadcast
industry.
The flexibility of the RocketIO™ multi-gigabit transceivers available in the Virtex-II Pro™ family
devices combined with the programmable logic of the Virtex-II Pro FPGAs makes it possible to
implement HD-SDI interfaces. Because every Virtex-II Pro FPGA has multiple RocketIO
transceivers, multiple HD-SDI interfaces can be integrated into one Virtex-II Pro device along with
other video processing functions.
This application note describes how to implement HD-SDI receivers. An HD-SDI receiver built in
a Virtex-II Pro FPGA is presented as a reference design.

XAPP687: 64B/66B Encoder/Decoder

This application note describes the encoding and decoding blocks of the 64B/66B encoding scheme.
This application allows designs to use the RocketIO™ transceiver of the Virtex-II Pro™ device or
an external SerDes with either Virtex-II™ or Virtex-II Pro devices.

Virtex-II Pro RocketIO Multi-Gigabit Transceiver

Characterization Summary

Virtex-II Pro devices contain up to twenty-four embedded RocketIO multi-gigabit transceivers
(MGTs) for the creation of high-speed serial links from chip-to-chip, across a backplane, or from
system-to-system. Each MGT has separate transmit and receive functions (full-duplex) and can be
operated at baud rates from 600 Mb/s to 3.125 Gb/s. Additionally, every RocketIO MGT block is
fully independent and contains a complete set of common SerDes (serializer/deserializer) functions.
This allows Virtex-II Pro devices to support many existing and emerging serial I/O standards at data
rates up to 10 Gb/s, including:

•
•
•

This document presents characterization data taken on Virtex-II Pro devices to verify the
performance of the MGTs with respect to these standards and the product specification.

Virtex-II Pro RocketIO MGT HSSDC2 Cable Characterization

RocketIO multi-gigabit transceivers (MGTs) in Virtex-II Pro Platform FPGAs are capable of
sending serial data at rates from 600 Mb/s to 3.125 Gb/s. Many links taking advantage of this
technology involve some length of cable through which these signals travel. At these speeds, cable
has the effect of degrading the quality of the signals, both distorting the waveforms and reducing
