XAPP670: Minimizing Receiver Elastic Buffer Delay in the Virtex-II Pro

RocketIO Transceiver

This application note describes a design that reduces latency through the receive elastic
buffer of the Virtex-II Pro™ RocketIO™ transceiver. This note is only applicable for
designs that do not use the clock correction or channel bonding features of the RocketIO
transceiver. (These operations can still be done in the fabric, if needed).
XAPP680: HD-SDI Transmitter Using Virtex-II Pro RocketIO Multi-Gigabit

Transceivers

The High-Definition Serial Digital Interface (HD-SDI) standard describes how to transport
high definition (HD) digital video serially over video coax cable. HD-SDI is used to
connect HD video equipment in broadcast studios and video production centers. It is an
evolution of the popular SDI standard that is widely used to transport standard-definition
(SD) digital video in the broadcast industry.
The flexibility of RocketIO™ multi-gigabit transceivers available in the Virtex-II Pro™
family devices combined with the programmable logic of Virtex-II Pro FPGAs makes it
possible to implement HD-SDI interfaces. Because every Virtex-II Pro FPGA has multiple
RocketIO transceivers, it is possible to integrate multiple HD-SDI interfaces into one
Virtex-II Pro device along with other video processing functions.
This application note describes the electrical specifications for HD-SDI transmitters and
the HD-SDI data format. It also presents several implementation examples and reference
designs for an HD-SDI transmitter implemented using the Virtex-II Pro FPGA.

built in a Virtex-II Pro FPGA is presented as a reference design.
XAPP683: Multi-Rate HD/SD-SDI Transmitter Using Virtex-II Pro RocketIO

Multi-Gigabit Transceivers

The SD-SDI standard is widely used in broadcast studios and video production centers to
transport standard definition (SD) digital video serially over video coax cable. The HD-SDI
standard is similar, but transports high-definition (HD) digital video. The SD-SDI and HD-
SDI standards are similar enough that it is possible to implement interfaces for video
equipment that support both standards through the same connector.
