Part Number: SN65LVCP402

Hi,

Our customers are thinking of a design like the one shown below.

Is it okay if the value of the capacitor for AC Coupling is 0.1uF?

Best Regards,

Hi Nishie-San,

This depends on the data pattern being used. RC time constant of AC coupling Cap, 50-ohm input impedance should be higher than longest running pattern(consecutive ones or zeros).
