Hi Team,

May I know the input signal for tTJ1BD test? Is there an standard document for LVDS buffer specs?

Thanks and Best Regards!

Hi Hao,

The input signal is a 700mV differential peak to peak waveform. A bias-tee is used to set the input common mode voltage to 1.2V which is typical for LVDS devices.

The wiki provides some good background on LVDS.
