Frequency Synthesizer Block Diagram. The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input. D9 d8 d7 d6 d5 d4 d3 d2 d1 d0.
Max2837 synthesizer block diagram. R 2 r 1 integer divider ratio. The high frequency vco tracks the stable low frequency reference in frequency and phase by comparing the divided down vco output to the reference input through the pfd.
The frequency divider modulus n can vary from 3 to 999 in single steps increment.
The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input. Block diagram of a common type of pll synthesizer. There are several different types of categories of synthesizer. Here is the schematic diagram of a low frequency synthesizer with a programmable three decades divider circuit.
