For power-of-2 integer division, a simple binary counter can be used, clocked by the input signal.

All articles with unsourced statements Articles with ratasheet statements from April Commons category link is on Wikidata. Care must be taken to ensure the tuning range of the driving circuit for example, a voltage-controlled oscillator must fall within the input locking range of the ILFD.

An arrangement of flipflops is a classic method for integer-n division. This is a type of shift register network that is clocked by the input signal.

Frequency divider

Analog frequency dividers are less common and used only at very high frequencies. The output signal is derived from one or more of the register outputs. Additional registers can be added to provide additional integer divisors.

Wikimedia Commons has media related to Frequency dividers. It operates similarly to an injection locked oscillator. The easiest configuration is a series where each dafasheet is a divide-by Digital dividers implemented in modern IC technologies can work up to darasheet of GHz.

In integrated circuit designs, this makes an ILFD sensitive to process variations. The six valid values of the counter are,and With a modulus controller, n is toggled between the two values so that the VCO alternates between one locked frequency and the other.

The VCO stabilizes at a frequency that is the time average of the two locked frequencies. Such frequency dividers were essential in the development of television.

This page was last edited datashwet 7 Octoberat By varying the percentage of time the frequency divider spends at the two divider values, the frequency of the locked VCO can be selected with very fine granularity. More complicated configurations have been found that generate odd factors such as a divide-by Integrated circuit logic families can provide a single chip solution for some common division ratios.

A regenerative frequency divider, also known as a Miller frequency divider[1] mixes the input signal with the feedback signal from the mixer. Frequency dividers can be implemented for both analog and digital applications.

Standard, classic logic chips that implement this or similar frequency division functions include the,and Another popular circuit to divide a digital signal by an even integer multiple is a Johnson counter.


The easiest configuration is a series where each D flip-flop is a divide-by Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a reference frequency. For example, a divide-by-6 divider can be constructed with a 3-register Johnson counter. The last register’s complemented output is fed back to the first register’s input.

This pattern repeats each time the network is clocked by the input signal. By adding additional logic gates to the chain of flip flops, other division ratios can be obtained.

Retrieved from ” https: Views Read Edit View history. A free-running oscillator which has a small amount of a higher-frequency signal fed to it will tend to oscillate in step with the input signal.

In an injection locked frequency divider, the frequency of the input signal is a multiple or fraction of the free-running frequency of the oscillator.

Proceedings of the IRE. In other projects Wikimedia Commons. For a series of three of these, such system would be a divide-by
