7700VMDA & 7700VMDA-2Q
SD-SDI Monitoring Reclocking Distribution Amplifier
The 7700VMDA Reclocking Distribution Amplifier provides inexpensive distribution and composite encoder monitoring of your SMPTE ST 259 (270MB/s) serial digital video signal. The 7700VMDA features an auto-equalized input with seven outputs that can be selected as either SDI or composite analog. The 7700VMDA-2Q has 2 channels, each with 3 selectable outputs or can be used as a single input DA with six outputs.
The 7700VMDA and 7700VMDA-2Q each occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
