Reason for R29 (R35 2010) 18 Ohm Resistor

The operation of transmitters designed to jam or block wireless communications is a violation of the Communications Act of 1934, as amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act prohibits any person from willfully or maliciously interfering with the radio communications of any station licensed or authorized under the Act or operated by the U.S. government. 47 U.S.C.

Reason for R29 (R35 2010) 18 Ohm Resistor

Post by josh_ridez »

I am wondering why there is a 18 ohm series resistor connected in series between the 2.5V regulator and the PLL (R29 for RC1A or R35 or 2010 version). I have looked at the datasheet for the PLL and none of the example schematics include this resistor.

Thanks.

Isn't it just a power supply filter for the PLL charge pump?
