What are the ppm drift specifications for the TPS65910 RTC crystal?

For the 32khz crystal attached between the OSC32KOUT and OSC32KIN pins, according to its datasheet, the frequency tolerance at 25C is +-10ppm.

Great, thank you for the information. Is it a similar specification for the other oscillator on the board, connected to the ARM?

Theres a 24MHz crystal between XTALOUT and XTALIN on the ARM. Its frequency tolerance at 25C is +/- 25ppm.

Note these numbers are based on a 3359-GX-226-RL RevD.
