Hi,
Recently I have a DSP filter project. From the DSP evaluation module circuit I found that for almost all digital outputs there are 33 ohm resistors connecting in series before to the target pin. I wonder if it is necessary as it would spend much PCB space in my custom board.
Thanks!
Thanks!
Acts as a series termination, to "kill" reflections on the driven line. You obviously need some trace length to go from one IC to another; an
0402 size chip will take no more space...ElectronDepot website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
