DS100BR210: Does DS100BR210 support the SMPTE 292?

Part Number: DS100BR210
Other Parts Discussed in Thread: LMH1218, LMH1219,

Hello,

In our application, we need to support both SMPTE 292 video input and output. So we plan to use both LMH1219 and LMH1218 for this application. The FPGA and the LMH1218 / LMH1219 are located on a separate card. So the diff pairs from FPGA' SerDes will be routed through the backplane card then to the LMH1219 / LMH1218 via several connectors.

Can I use the DS100BR210 to re-drive the signals from an FPGA' SerDes Rx/Tx then feed them to the LMH1218 / LMH1219 for SMPTE 292? 

Thanks in advance!

    Hi Alice,

    Yes DS100BR210 can support lower data rates such as SMPTE292 running at 1.48Gbps. I am not sure if pathological data pattern would be used in this application. This is a video test pattern. This pattern has long string of ones or zeros. When AC coupling these devices - to prevent or reduce dc wander - please make sure you use as high AC coupling Cap value as possible.

    Hi Nasser,

    Thank you for your prompt reply!

    Another question for the setting of the MODE pin of the DS100BR210. Which one should I use for our application?

    Controls Device Mode of Operation
    High= 10GbE Mode, Continuous Talk (Output Always On)
    Float = 10G-KR Mode, Slow OOB MODE 18 LVCMOS

    20 kΩ to GND = eSATA Mode, Fast OOB, Auto Low Power on 100 µs of inactivity. SD
    stays active.
    1 kΩ to GND = SAS Mode, Fast OOB

    Thanks.

    Hi Alice,

    Please use High - 10GbE mode.
