NRF8001 dc/dc converter enabled schematic

[Hisham]

Hello,

I attached the schematic found in the manual for NRF8001, in the case of DC/DC converter enabled. It shows that an external 32.768KHZ crystal is used, while in the table(also attached) shows that in case the DC/Dc converter to be enabled the external crystal cannot be used.

Please clarify if i have to add the external crystal in case i want to use the DC/Dc converter.

Thanks

Please if some one can explain what is the role of L1, L2 and L3, C5 and C6?

That's the impedance matching network before the antenna
