LVDS transciever interface with BGR

[jt_rf]

Hi,

I am facing problems integrating BGR voltage and current reference with LVDS transceiver. supply & ground noise couples to the bgr output.

Should the supply for BGR and LVDS be different or same?? shud be separate pad or separate pin?

any info on this would be very useful??

what is the general practise? to merge both or isolate both supply and ground?


thanks
JT

if the POWER bus can be split, it is better,
if can not, please use large bypass cap to isolate the power or gnd noise.

use separate power supply ground pins for both
