Part Number: DS91M040
I connected togheter DE and /RE pin of M-LVDS transceiver. Usually this signal is low, so the receiver is enabled. When I put this signal high, I try to change from receiver enabled to driver enabled, I see about 4us with the differential output not ready to transmit, like in Z state.
In the next figure, It's possible to see the output pins A and B referred to GND during this transition.:
After this transition the driver works well.
In the data sheet is reported the very short Enable time (Z to Active High and Low), few ns.
But in my case I'm switching from Receiver to Driver. Is this delay expected? How long can it be?
Thank you for your answer
