Hi

We want to transmit SMPTE292M(HD-SDI) by Twisted Pair.

　　-Twisted Pair : AWG24, Zdiff=100Ω, 20m

Could you tell us recommend device (Cable Driver, Equalizer, Reclocker).


Best regards,

Itabi

    Hello,

    We are not familiar with this spec, so we would like to know more about your transmitter. Is is working @1.5Gbps?, How many lanes do you want to implement?, How long would be the transmission? what are the electrical specs to meet (i. e. eye diagram, VOD, VOL, VOH, VCM), Is it a CML or LVDS implementation?.

    Regards,
    Diego.

    Hello Diego-San,

    Thank you for your reply.

    It is working @1.5Gbps.
    The transmission distance is 20m.

    The others are uncertain.

    Hi Itabi-san,

    You can find more SDI related posts in the High Speed Interface forum.

    You can find a full listing of TI's SDI products at: www.ti.com/sdi

    For your application do you require SD/HD only? Or do you also need to support 3G datarates? One device to consider is the LMH0302 or the LMH0202.

    For cable equalization please consider the LMH044 or the LMH384 and LMH394.

    If you require a reclocker, please consider the LMH0046 and LMH0056 or the LMH0346 and LMH0356.
