bus (FA3(4:0)) between LO1 and LO2. There are 31 steps
In order to increase the adjustment range of VCO3 with
fixed external tank elements and/or for "band switching",
especially for US frequencies, VCO3 has programmable
capacitors inside. These capacitators can be added by serial
available, every step adding a capacitor of 0 5 pF.
