Cable extended IC for LVDS signal (like DS15BA101 or DS15EA101)

Other Parts Discussed in Thread: DS15EA101, DS15BA101, DS30BA101

Dear Sirs

I use DS15BA101 or DS15EA101 for cable extended application.

The LVDS max output signal is 400mv.

Does TI provide similar IC but LVDS max output signal is 500~600mv?

Thanks

    Hi Nat,

    Our DS15BA101 and DS30BA101 cable drivers are designed to output a maximum of approximately 450 mVpp single-ended (900 mVpp differentially), and we do not have a higher max output signal alternative.

    Can you clarify your question? Are you asking for differential or single-ended 500-600 mV? Is it possible that you are asking for 500-600 mVpp?

    Thanks,

    Michael

    Dear Michael

    Thanks for your help.

    I see DS15BA101  datasheet.

    The Output Voltage is 400mVpp (Single-ended, 25Ω load RVO = 953Ω 1%).=>Does it mean the Output Voltage is 800mVpp (for differential output)?

    The Output Voltage is 800mVpp(Single-ended, 25Ω load RVO = 487Ω 1%).=>Does it mean the Output Voltage is 1600mVpp (for differential output)?

    Thanks

    Hi Nat,

    Yes the output measured deferentially (out+ - out-) will be twice the single-ended amplitude.

    Also LVDS is somewhat unique in that the output VOD specification is (out+ - out-)/2.  Yielding 1/2 the peak-to-peak amplitude of the output signal.  A typical LVDS device will have a peak-to-peak amplitude of 700mV into a 100 ohm load.
