Hi team,

Per UB936 datasheet, PoC need 4.02K resistor, is it must 4.02K? is 4K ok? Thanks!

Hello Jiawei,

4k should also be ok here

Best Regards,

Hi Casey.

Thanks for your reply! Could you kindly tell me what is the range of this resistor?

Hello Jiawei,

We have never characterized a tolerance for this resistor but this resistor is just used to dampen the Q-factor of the LC filter here. A 200 ohm difference should not cause an issue but if the customer wants to sweep the value of this resistor and judge the affect on the system s-parameters, they would need to complete that task on their side

Best Regards,

Casey
