10.2.5 Input Frequencies and PS Key Settings
BlueCore4-ROM Plug-n-Go should be configured to operate with the chosen reference frequency. This is
accomplished by setting the PS Key PSKEY_ANA_FREQ (0x1fe) for all frequencies with an integer multiple of
250kHz. The input frequency default setting in BlueCore4-ROM Plug-n-Go is 26MHz.
The following CDMA/3G TCXO frequencies are also catered for: 7.68, 14.4, 15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8
and 38.4MHz.
