CDCM6208 - Output LVDS swing

Other Parts Discussed in Thread: CDCLVP1212, CDCM6208, CDCLVD1212

Hi,

We are connecting LVDS output from CDCM6208 to buffer (CDCLVP1212) via AC coupling. We are performing SI analysis on this net using the IBIS model provided by TI. the output waveform is attached with this post. It is seen that the Differential Swing (Red) is not centered wrt Zero but to 0.3V and the differential signal,  instead of swinging from -0.3 to +0.3 is swinging rather at 0 to +0.6V which is not the correct LVDS signal.

This offset is because both CLKp and CLKn are not perfectly differential to each other. Can you please verify whether there is a issue with IBIS model or is this is the Signal format which is expected from CDCM6208
