LMH1219: IN1+/- supported data rates

K.Shidara
Expert 3225 points
Part Number: LMH1219

Hi Team,

Thanks for usual prompt reply.

Let me clarify my understanding about "Table 3 supported data rates" shows below in datasheet.

Even though IN1+- does not contain SMPTE rate such like 2.97 and 1.485Gbps etc, but the reason is only an default state.

SMPTE data rates are also supported by the register setting. Is my understanding correct?

Thanks

Best regards,

Shidara

    Hi Shidara-San,
    Your understanding is correct. Through register settings you can use IN1 with SMPTE data rates as well.
    Also, you can use IN0 and set it for 10GbE too - through register setting. This is not a typical application but you can do this.
    Please note section 3.5 of the LMH1219 programming guide for detailed SMPTE or 10GbE selection.
