Other Parts Discussed in Thread: SN74AVC16T245,
I want to use ADS4225 with 120MHz sampling rate and CMOS Mode. I'm afraid of output impedance mis-match of data bus. It is not easy to use it with LVDS Mode. Therefore I'm considering impedance matching by using external resistors with CMOS Mode. However there are no descriptions about output impedance of data bus on the data sheet of the device. Does it make sense to consider the impedance matching with CMOS Mode? Or do you think I'd better not use CMOS Mode with 120MHz sampling rate? I also think that I should shorten the data line on my PCB design as much as possible without considering impedance matching. Would you please tell me your opinions?
