If an external clock is used, the applied
data rate may deviate from the set clock
rate by
±2 %. The external clock can be
used for internal and external data.
operating mode internal, external
setting range
ASK, PSK, QAM 400 Hz to 25 MHz
FSK 400 Hz to 15 MHz
resolution 0.001 Hz
frequency uncertainty (internal)
<5 Ч 10 –14 Ч symbol rate + reference
frequency uncertainty
external clock symbol, K × symbol, bit clock
clock divider K 1 to 64
Symbol rate
external clock rate max. 100 MHz
With the aid of the frequency offset, the
center frequency of the modulation signal
in the baseband can be shifted. The
restrictions caused by the modulation
bandwidth apply.

In the case of serial transmission, the
symbol strobe marks the LSB of the
symbol, and the maximum symbol rate is
limited by the data rate of the interface.
