Other Parts Discussed in Thread: CC2642R, CC2340R5

Hi team,

For CC2640R2 or CC2642R, user can follow swra460 (https://www.ti.com/lit/an/swra640g/swra640g.pdf ), chap6.3 to tuning the HF Oscillator in CCFG (set cap-array delta value).

Customer ask if CC2340R5 use the similar method ?

    Hi Jerry,

    While are steps and concepts are similar it is not exact since the CC2340 device will have different CCFG/registers. There will be a separate app note specifically for the crystal tuning the CC2340.

    Can the customer wait until the the app note is released or is there an urgent need to tune the crystal?

    Best regards,

    Bun
