CC3100 & CC3200 - quartz crystal or TCXO?

Hi,

the evaluation board of the CC3100 transceiver has the following quartz crystal:

EPSON Q24FA20H00396

http://www.digikey.com/Web%20Export/Supplier%20Content/EpsonToyocom_114/PDF/Epson_FA_20H.pdf?redirected=1

That is a +/- 10 ppm crystal. That means an initial frequency deviation of +/- 24 kHz at 2.4 GHz

Question:

Why didn't you use a TCXO?

thanks,

Enrico Migliore
