Recommended Settings for ISM Frequencies
The recommended frequency synthesiser
settings for a few operating frequencies in
the popular ISM bands are shown in Table
27. These settings ensure optimum
configuration of the synthesiser in receive
mode for best sensitivity. For some
settings of the synthesiser (combinations
of RF frequencies and reference
frequency), the receiver sensitivity is
degraded. The performance of the
transmitter is not affected by the settings,
but recommended transmitter settings are
included for completeness. The FSK
frequency separation is set to 64 kHz. The
SmartRF Studio can be used to generate
the optimised configuration data as well.
Also an application note (AN011) and a
spreadsheet are available from Chipcon
generating configuration data for any
frequency giving optimum sensitivity.
