Here is the block diagram of a basic synthesiser. The “R-counter” generates the reference frequency. In the MC145152-2 you have about 3 different options. In mine you will have over 2000 different options. The reference frequency can be interpreted as the channel-spacing of the final synthesiser. The “N-counter” divides the output of the external voltage-controlled […]
