There is a driver in my circuit which is the LVPECL output, I use the AC couple between the output and the reciver.
It was konwn that output should connect 200 ohm resistor to the GND before the coupling capacitor to provide 14ma current for the OE output.
Since it's 1:10 driver,and each differential output should connect 200ohm resistor,I was wondering whether I can ues one 200 ohm resistor arrays instead of four singal resistors.But I 'm not sure whether there is a crosstalk or something in this kind of application. By the way,the output frequence is 400Mhz.
Could anyone give me some advises?
