A shortened serial interface write where
/CS
is from 2 to 12
Clock
cycles wide and modulation data (2 to
12 bits) is presented on the
Mod_in
pin. The
Mod_in
is the alternate pin for entering modulation data
directly in
modulation data register
with shortened
/CS
strobes. This mode is selected through the
modulation control register
. This method of data entry also eliminates the register address overhead on the
serial interface and permits a different device than the one controlling the channel selection to enter the
modulation data (eg. a microcontroller for channel selection and a DSP for modulation data). All serial
interface bits are re-synchronized internally at the reference oscillator frequency and the content of the
modulation data register
is passed to the
modulation unit
at the next falling edge of the divided main VCO
frequency (F
pd_main
).
Modulation data samples in the
modulation data register
can be from 2 to 12 bits long, enabling the user to
select how many distinct frequency steps will be used for the desired modulation scheme.
The user can also control the frequency deviation through the
Modulation Data Magnitude Offset
in the
modulation control register
. This permits shifting of the modulation data to accomplish a 2
m
multiplication
of frequency deviation
1
.

The programmable range of -0.5 to +0.5 of the main
Σ
modulator can be exceeded up to the condition where the sum of the dividend and the

)
≤
+0.5625
before requiring changing
