Rf_Frequency: the frequency of the RF part of the PLL. This is the sampling
frequency of the ADC.
If_Frequency: the frequency of the IF part of the PLL. This parameter must be zero.
*if_r, *if_n, *rf_r, *rf_n: the calculated values are returned into these variables. Refer
to the LMX2330U user guide for the details of the registers.
Library SY89430V
SY89430V_Parameters()
This function generated the parameters to use to configure the SY89430V
component for the requested frequency.
Prototype
unsigned int SY89430V_Parameters (unsigned int frequency);
Return value
The value to use the configure the SY89430V for the specified frequency. The value
returned should be written in the clock synthesiser setup register
(SMT391_ADJ_CLK_CNTRL_REG).
Parameters
Frequency: the requested frequency.
