Part Number: SN75LVDS83A

Hi

Pls advise should i use any TVS/ESD array to the o/p of SN75LVDS83A while connecting to LCD panel.

Do i need to place ESD array in  all 4 differential o/p & clock o/p.

    Hi,

    The SN75LVDS83A transmitter offers good ESD protection (5 kV HBM).  For optimal performance, we advise against using discrete ESD protection on the output line because these components can introduce parasitic capacitance and slow down the output edges.  Depending on your application, you may have margin for this, and if you carefully choose these components and are careful with your layout, it can be done successfully.

    If you choose to add these discrete components to the SN75LVDS83A output, it is best to choose components with low capacitance and small body size.  Small component size is important in order to maintain the impedance control on the output, because large component pads will have a negative effect on this impedance and the output return loss.
