Hi team,

The RES2 pin requires 50 ohm resistor to GND. Can I use 47 ohm +/-5% resistor at RES2 pin of DS90UH949A-Q1?

Hello Nishimura-san,

unfortunately, it is not recommended to use that value. This is an external termination which should be as close as possible to 50ohm with tight tolerence.

You may use 49.9ohm or 51ohm, with 1% tolerence.
