Sn65LVDS388/389/390 forms latch in the circuit

Hi Sahit,

The SN65LVDS388 is a simple LVDS buffer and does not require any sort of input clocking. It features an open circuit fail safe that allows the SN65LVDS388 to start switching accordingly as long as there is a DC common mode voltage present on the input.

The maximum part to part skew is specified in the data sheet to be 1nS so as long as your design can tolerate this delay you shouldn't have to worry about the part to part skew. Please let me know if you have any additional questions?

Regards,

Mike

Hi Sahit,

The way to interpret that spec is that you can expect a maximum part to part skew of 1nS between any SN65LVDS388/389/390 device that is in your system. It does not mater if you measure between devices 1 and 2 or between 1 and 128.

Hey mike,

Thanks for your reply mike. I wanted to ask  few other question regarding set up times and hold times... can i mail u few questions ? can i use this email address mpeffers @ti.com ?

Thank you

mike                                           I appreciate it  

Hi Sahit,

That is fine, I look forward to hearing from you.

Regards,

Mike
