SFS-8221
Single Channel MD-SDI Frame Synchronizer
Video and audio frame synchronizers for all Standard and High-Definition SDI signals.

The SFS-8221 is single channel Multi-Definition SDI frame synchronizer designed for re-timing applications in both standard and high-definition environments.

Multi-Definition Support
The SFS-8221 supports all popular standard-definition and high-definition video formats including 480i, 576i, 720p and 1080i. The format of incoming video is automatically detected, simplifying system setup.

Single Channel SFS-8221
The SFS-8221 accepts an SDI signal of either standard-definition (270Mb/s) or high-definition (1.485Gb/s), automatically equalizing for cable loss and providing a reclocked SDI output. The video is then synchronized to either a frame-wide reference or a local reference. For further flexibility in resolving system timing problems, additional fixed delay can be added to the video.

Monitoring Output
For simplified setup and monitoring, a composite NTSC/PAL monitoring output is provided. This output can display both the video as well as a comprehensive Heads-Up menu system. Status and operating parameters can be overlayed on the video and settings can be adjusted easily using the card-mounted finger joystick.

Flexible Timing Reference
openGear frames support a distributed frame reference, allowing a single incoming reference sync signal to feed timing information to all modules in a frame. Thus, a single composite or tri-level sync signal can be used for multiple frame synchronizers. Alternatively, each frame synchronizer accepts an additional local reference signal to provide additional system timing flexibility.

Ancillary Data Support
Ancillary data (VANC) is protected, and is passed from input to output, ensuring data is not lost during the frame sync operation.

The SFS-8221 is housed in our DFR-8310 series frames.
