Technical details and manufacturing context for Frequency Divider Counter

Definition

The Frequency Divider Counter is a specialized counter circuit used within frequency dividers or multipliers. It tracks the number of input signal cycles and generates an output pulse after a predetermined count, effectively dividing the input frequency by a specific integer value. This component is essential in applications requiring precise frequency scaling, such as clock generation, signal conditioning, and timing control in electronic systems.

The counter increments with each input signal cycle. When it reaches a preset count value (the division ratio), it resets and generates an output pulse. This creates an output frequency equal to the input frequency divided by the preset count value. The division ratio is programmable via external pins, allowing flexibility in setting the output frequency.

Key parameters include an input frequency range of 0.1–100 MHz, a division ratio of 2–1024, and an output frequency accuracy of ±0.01% relative to the input frequency. The supply voltage range is 3.3–5.0 V DC, and the operating temperature range is -40 to 85 °C (IEC 60068-2-1), with a storage range of -55 to 125 °C (IEC 60068-2-2). The input signal level is TTL/CMOS compatible (0–VCC), and the output drive capability is ±24 mA (sink/source). Propagation delay is ≤10 ns, rise/fall time ≤5 ns at 50 pF load, and power consumption ≤50 mW at 5 V supply and 100 MHz. The package type is SOIC-8 (JEDEC MS-012), and operating humidity range is 5–95% RH (non-condensing, IEC 60068-2-78).

Materials on file include semiconductor silicon, copper, and plastic. This component is a part-level product within the Computer, Electronic and Optical Product Manufacturing industry. Always verify model-specific values and standards with the legal manufacturer or supplier before integration.

Working Principle

The counter increments with each input signal cycle. When it reaches a preset count value (division ratio), it resets and generates an output pulse. This creates an output frequency equal to the input frequency divided by the preset count value. The division ratio is programmable via external pins, allowing the user to set the desired frequency division. The output pulse is generated after the counter reaches the preset count, ensuring accurate frequency division. The counter operates within specified input frequency and voltage ranges, and its performance is subject to environmental conditions such as temperature and humidity.
