For sale is ONE (1) used 7746FSE-HD board in very good condition. It comes with a corresponding backplane +3RU. We have a few units for sale (1 per listing price). This is one of them. All others are in same condition.
The 7746FSE-HD series HD/SD Frame Synchronizers are designed to re-time a SMPTE 292M (1080i/60, 1080i/59.94, 1080i/50, 1080p/24sF, 1080p/23.98sF, 720p/60, 720p/59.94, or 480p/59.94) or SMPTE259M (625i/50, 525i/59.94 ) input to a local reference tri-level or composite sync signal. When necessary, frames are repeated or dropped to maintain synchronization. During the synchronizing process the video delay nvaries from 3 lines through to 1 frame plus 3 lines. Additional delay can be added to the synchronizing process in 1 frame increments.
The frame synchronizers have the ability to adjust video parameters such as brightness, contrast and saturation. Hue control is available for SD standards (525i/59.94 and 625i/50). They can also adjust audio parameters such as gain, mixing stereo pairs into monaural and reassignment of audio channels.
