Part Number: SN65LVDS125A
dear TI buddy
my customer used SN65LVDS125A to design a lvds project, but the output waveform is not symmetrical,besides,the output amplitude(Vpn) is only 100mv when i connect the LCD panel,if disconnect the LCD,the output ampitude is about 300mv.
the attachment is schematic and the output waveform.
can you help me explain why like this? and how should i resolve the issue.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Clemens Ladisch:
the waveform is after the RCLAMP/ESD components,that is to say we measure the signal at E0_P1/E0_N1,
about the impedances ,customer cant measure;
LCD input terminate is CN1(P50-2D54-NJ ),they connect the LCD by row needle.
i think this is impedance match issue,how should i adjust our SN65LVDS125A's output impedance.
