DS15BR400: DS15BR400 Consulting

Part Number: DS15BR400
Other Parts Discussed in Thread: DS15BR401,

Hello

If my understanding is right through other post ,e2e.ti.com/.../2423462

My understanding: the DS15BR400 's input 100ohm internal terminate resistor will have some bad influence for CML to LVDS ? so you advice use DS15BR401 as the DS15BR401 input does not have resistor.

  • I do not see a problem in this case, the transmitted signal impedance, the T-line impedance, and the Rx impedance are all matched at 100 ohm differential.  This should work well.  It is possible to use an internal Rx termination or external Rx termination in either case.

    Regards,
