Frequency Divider/Multiplier Component

Product Specifications

Technical details and manufacturing context for Frequency Divider/Multiplier

Definition

A frequency divider/multiplier is a component used in clock and timer units to alter the frequency of an input clock signal. It generates an output signal whose frequency is either a precise fraction (divider) or a multiple (multiplier) of the input frequency. This capability is essential for producing the various timing signals required by different subsystems within electronic devices, such as microprocessors, communication interfaces, and data converters. The component operates over an input frequency range of 1 to 100 MHz and can produce output frequencies from 0.001 to 1000 MHz. Division ratios range from 1 to 1024, while multiplication factors range from 1 to 32. The output duty cycle is typically 45% to 55% at nominal frequency. Phase noise at a 10 kHz offset is between -120 and -100 dBc/Hz. The device operates from a single 3.3 to 5.0 V supply and has an ambient temperature range listed as -40 to 85 °C, requiring model-specific confirmation. Input signal levels are 0.8 to 2.0 Vpp, and output levels are 1.0 to 3.3 Vpp. Rise and fall times are 1 to 5 ns (10% to 90% of output swing). Power consumption at maximum frequency is 0.1 to 0.5 W. The component is available in a surface-mount SOP-8 package (JEDEC MS-012) and weighs 0.1 to 0.5 g. Typical materials include silicon semiconductor, copper interconnects, and ceramic or plastic packaging. These specifications are reference ranges; actual values must be confirmed with the legal manufacturer for the specific model and application.

Working Principle

The frequency divider uses digital logic circuits, such as flip-flops, to count input clock cycles and produce an output pulse after a set number of cycles, thereby dividing the frequency. The frequency multiplier employs a phase-locked loop (PLL) that compares the phase of a voltage-controlled oscillator's output to the input signal, adjusting the oscillator until it locks at a higher, synchronized frequency. This allows precise multiplication of the input frequency.

Components / BOM

Phase Detector
Compares the phase of the input reference signal and the feedback signal, generating an error voltage.

Material: Semiconductor (Silicon)
Voltage-Controlled Oscillator (VCO)
Generates the output frequency, which is controlled by the input voltage from the loop filter.

Material: Semiconductor (Silicon), Inductor/Resonator
Loop Filter
Filters the error signal from the phase detector to provide a stable control voltage for the VCO.

Material: Resistors, Capacitors (Silicon or Discrete)
Feedback Divider
Divides the VCO output frequency down to match the reference input frequency for comparison in the phase detector.

Frequently Asked Questions

What is the difference between a frequency divider and a multiplier?

A frequency divider reduces the input frequency by an integer division ratio (1 to 1024), while a multiplier increases it by an integer factor (1 to 32). Both are used to generate different timing signals from a reference clock.

What are the typical input and output frequency ranges?

The input frequency range is 1 to 100 MHz. The output frequency range is 0.001 to 1000 MHz, depending on the division or multiplication factor used.

What supply voltage is required?

The component operates from a single supply voltage of 3.3 to 5.0 V. Always verify the exact voltage requirements for the specific model.

What is the operating temperature range?

The listed operating-temperature range is -40 to 85 °C. Confirm the exact range and qualification evidence for the specific model and application environment.
