Reference design puts video over USB
A new high-performance reference design targets streaming video and isochronous USB applications
A new high-performance reference design kit targets streaming video and isochronous USB applications. Cypress also plans to introduce an enhanced version of the kit compatible with the Video Device Class Specification released this month by the USB Implementers' Forum. The new CYStream kit, designed to be used in conjunction with Cypress's EZ-USBT FX2 USB 2.0 integrated microcontroller, provides a reference platform that demonstrates the devices' ability to stream data through high-bandwidth isochronous and bulk end-points.

The kit delivers 24Mbyte/s throughput and includes: firmware code examples illustrating how to implement isochronous and streaming data transfers with EZ-USB FX2; a CYStream Windows application program that USB developers can use to experiment with different streaming options and endpoint configurations to achieve the best possible throughput; a USB 2.0 device driver for the CYStream application supporting streaming data, including isochronous transfers; and extensive support documentation.
The device extends the plug-and-play simplicity of USB to more complex, bandwidth-hungry applications, including USB-enabled TV tuners, personal video recorders and video compression devices.
"Video and audio applications that require continuous data flow without interruption use streaming to transfer data, but the designs are typically very challenging", said Cedric Van Rossum, Product Manager for Cypress's EZ-USB devices.
"CYStream, when combined with Cypress's EZ-USB FX2, simplifies this process and is an important 'first step' toward bringing video-over-USB to the PC".
The CYStream reference design kit (CY4603) is available for download from Cypress's website at no cost.
The enhanced version of the kit will be made available in Q3.
