Hi.Connecting as fig.46 datasheet, is it necessary bias resistor ? If not , what do i have in a momentary transistion with all device in receving state? Is it necessary a ground conection on the bus among the devices ? the total lenght of bus (9 devices…
Hello ,
My name is Meir and I am DFAE.
One of my customers use the ADM2687 - Signal and Power Isolated RS-485 Transceiver.
They have an emission issue on ~180MHz frequency and 360MHz frequency (the second harmony) and they can't to pass the EMC…

From the data sheet for ADM2687 I see application information on page 18 for decoupling capacitors for the device. I have a question about the 10uF capacitor that the data sheet suggests. I'm in the process of defining the capacitor part numbers to use…
Hi.
My name is Dmitry, I'm ADI rep. FAE.
My customer (annual volume is 200.000-300.000 pc/year) asked is it possible to implement ADM2687E on 2 layer PCB like ADE2587E (UG-916 ) to reach the same radiated emissions?
Thank you.
Hi All -
We are spinning a board which uses your very fine ADM2687 and are planning to add some degree of ESD protection.
Not trying to meet any particular standard at this time.
An MCC SM712 and 10 ohm series resistors as per AN-960 seems like a good…
