The datasheet and EVM for the LMX2485 indicates each supply rail pin needs an 18 ohm series resistor to create a low pass filter.
There is concern this creates a high component requirement to have each of these power rails with its separate, unique low pass filter.
Although it is recommended in the datasheet, what concerns are there if only 1 18 ohm resistor is used to create a common supply to each of the power pins?
