Condition

Binary FSK frequency

separation

kHz

The frequency corresponding

to the digital "0" is denoted f0,

while f1 corresponds to a

digital "1".

The frequency separation is

f1-f0. The RF carrier

frequency, fc, is then given by

fc=(f0+f1)/2.

(The frequency deviation is

given by fd=+/-(f1-f0)/2 )

The frequency separation is

programmable in 250 Hz

steps. Separations up to 65

kHz are guaranteed at 1 MHz

reference frequency. Larger

separations can be achieved

at higher reference

frequencies

Conducted measur at

maximum output power. An

external LC filter should be

used to reduce harmonics

emission to comply with SRD

requirements. See p.128
