TB-FMCH-3GSDI2A由 National Semiconductor的3G/HD/SD SDI 均衡器,"LMH0387" x 6驱动器,视频时钟发生器"LMH1983"和多格式视频同步分离器”LMH1981”组成。
该板卡通过Samtec的DIN同轴连接器 "DIN7A-J-P-GFRA-BH1"进行SDI均衡,驱动输入输出和多格式视频同步分离器模拟视频输入。
同时,该板卡还有2个Samtec的FMC接口,一个和载板连接,一个增加输入输出SDI均衡器/驱动的数量。

The 3GSDI FMC Connectivity mezzanine card is designed to provide 2ch input, 2ch output and 2ch by-directional channels of 3G/HD/SD SDI format with the connection between FMC (HPC) connector. It could expand up to 4ch input, 4ch output and 4ch by-directional channels by using expansion connector.
The TB-FMCH-3GSDI2A board consists of TI's 3G/HD/SD SDI equalizer/driver "LMH0387" x 6, video clock generator "LMH1983" and multi-format video sync separator "LMH1981".
It also has two on board crystals (148.5MHz and 148.3516MHz) which each can be reference clocks.
The board uses Samtec‘s DIN coaxial connector "DIN7A-J-P-GFRA-BH1" for SDI equalizer/driver input/output and multi-format video sync separator analog video input.
