The NBC12439FNR2 is a clock generator from ON Semiconductor Corporation. It is part of their Clock/Timing offering. This article will discuss the application field of the NBC12439FNR2 and explain the working principle behind it.

The NBC12439FNR2 is an oscillator which serves as an on-chip clock signal generator. The oscillator features a low-power 45-MHz oscillator, low-dropout voltage regulator, and an output stage buffer. It is designed to be used in a wide variety of applications, such as microprocessors, digital signal processors, medical equipment, gaming systems, and consumer electronics.

The 45-MHz oscillator can be used to generate local oscillator (LO) frequencies for use in radio frequency (RF) applications or as a reference clock signal for digital communication systems. This low-power oscillator is also suitable for low-speed applications, such as real-time clock (RTC), power management, peripheral control, and general-purpose timers. The oscillator is also very efficient and offers the user an option for clock frequency slewing (FFS).

The low-dropout voltage regulator is designed to provide a regulated output voltage for the oscillator. The voltage regulator allows for a wide range of input voltages, from 2.7V to 5.5V, and a wide range of output voltages, from 0.6V to 5V. It also features a 3.3V intermediate voltage. This flexibility makes the NBC12439FNR2 suitable for a variety of applications.

The output stage of the NBC12439FNR2 consists of two outputs, one fixed at 3.3V and one adjustable from 3.3V to 4.6V. The output stage also features a high impedance, low-noise output for driving low-power, low-speed peripheral circuits. The output stage also includes capacitor-free, low-impedance outputs for driving higher-power and higher-speed circuits. The output stage also features adjustable slew rate control and spread-spectrum outputs, which help reduce EMI.

The NBC12439FNR2 operates on a principle called phase-locked loop (PLL) technology. The PLL is used to synchronize the on-chip oscillator frequency to an external reference. The reference can be a known frequency, or it can be derived from the output of another oscillator or synthesizer. The PLL is used to adjust the output frequency of the on-chip oscillator to match the frequency of the reference, allowing the frequencies to stay in sync. This is a very important feature for highly accurate applications, such as in communications systems and complex digital systems.

The NBC12439FNR2 is an excellent choice for a wide variety of applications, due to its ability to provide accurate, low-power clocks for a variety of purposes. Its application field includes microprocessors, digital signal processors, medical equipment, gaming systems, and consumer electronics. The oscillator also looks to have low-power consumption and low-dropout voltage regulation. It additionally has spread-spectrum capability for EMI and adjustable output frequency slewing for higher stability and accuracy. The device also features PLL synchronization for precise synchronization between external references and the on-chip clock.
