TM4C123BH6PGE: Crystal Spec for MOSC

Part Number: TM4C123BH6PGE

I'm going to use TM4C123BH6PGE.

I want to use TXC crystal for MOSC. Its specification is below.

- Frequency 25 MHz

- Tolerance : 100 ppm

- Stability : 100 ppm

In Table 23-19 in  the datasheet (SPMS367E), it seems that Tolerance is limited up to 30 ppm and Stability is up to 50 ppm.

Can I use the crystal 100 / 100 ppm for MOSC?

Best Regards,

Satoshi Shinohara

    Hi Satoshi-san,

      The table 23-19 lists the crystals that have simulated and confirmed to operate within the specification in table 23-18. It is by no means comprehensive to cover all the crystals. I think the best way is for you to consult with the crystal manufacture if your selected crystal is meeting the spec requirements in table 23-18. In my opinion, the crystal you selected will be fine. With that said, it is best for you to consult with the crystal vendor.
