Product data sheet
7.5 PLL
7.6 DAA
The fast synthesizer PLL tuning system with local control is used for inaudible AF
updating, combining fast PLL jumps with low reference frequency breakthrough.
It is capable of tuning the following FM and AM bands:
To reduce the number of manual alignments in production, the following I
Digital Auto Alignment (DAA) functions are included:

– 5-bit DAC for adjustment of the crystal oscillator frequency to align the actual IF
tuning voltage
this case, pin DAATD must be connected to ground, which reduces the available
alignment range (see
frequency to the center frequency of IF selectivity inside the IF DSP. If the IF DSP
can be aligned to the actual IF frequency, this DAA output can be used as general
purpose DAC.
