nRF52 crystal - possible to use an external 64MHz crystal?

[MANGO]

Hi, I'm planning to create a custom PCB that uses nRF52832-QFAA.

Currently, I chose the Q22FA12800025 32MHz crystal to use, which is the same one in the PCA10040, I believe.

The nRF52832's product spec v1 says that the CPU clock is 64 MHz.

So I was just curious whether I can you an external 64MHz crystal, although it is far more expensive than using a 32MHz.

Is it possible to use an external 64MHz crystal for the nRF52832?

P.S.) Is there an alternative for the Q22FA12800025? I'm looking for cheaper 32MHz crystal.

I wish to know what factor (Frequency Stability / Tolerance or Load Cap) impacts the radio performance.

-Best Regards, Mango

No it's not possible to use a 64MHz crystal.

The specs for tolerance and load capacitance are all in the data sheet.
