Programmable oscillators are a type of oscillator used to generate a clock signal or other type of oscillatory waveform. They are similar to traditional quarts oscillators, but with the added flexibility of being configurable via a microchip or other programmable logic controller. The SIT3809AC-2-33NB series of programmable oscillators are manufactured by Shanghai Intersil Corporation, a leading supplier of interface products in Asia-Pacific region.

The SIT3809AC-2-33NB series is a programmable oscillator, which has many advantages over the traditional quartz oscillator. The SIT3809AC-2-33NB series is a low-cost and reliable option for applications requiring a high output frequency accuracy and long-term stability. Its frequency range covers both the fundamental, and 1/2 and 1/4 secondary frequencies. This helps to increase the accuracy and stability of the oscillator in the frequency range.

The SIT3809AC-2-33NB series is suitable for applications such as metering applications, timing control, phase locked loops, clock synchronization and pulse shaping. The oscillator can be easily programmed with a microcontroller, allowing the user to precisely set the frequency, period, and duty cycle of the output waveform. The SIT3809AC-2-33NB series has a wide dynamic operating temperature range, making it suitable for use in harsh or extreme environments.

The working principle of the SIT3809AC-2-33NB programmable oscillator is based on the principle of frequency division. This involves dividing the input frequency by a predetermined factor and providing the output as a fixed frequency. The frequency division is achieved by the use of a Flip-Flop circuit, that acts as a control block for the oscillator. The Flip-Flop circuit test the input frequency and outputs a fixed frequency after division. The division factor is determined by the oscillator’s programming code.

The SIT3809AC-2-33NB also has an SSOP (Shrink Small Outline Package) that further enhances its usability in compact applications. The SSOP reduces the size of the board space needed and also improves the overall electrical performance of the oscillator. The SIT3809AC-2-33NB series also offers better noise immunity than quartz oscillators and has a very low power consumption. Additionally, SIT3809AC-2-33NB series features built-in self-test functionality, which is useful to ensure proper operation and debugging in the field.

In conclusion, the SIT3809AC-2-33NB is a programmable oscillator that offers a wide range of advantages when compared to its traditional quartz oscillator counterpart. Its low cost, wide operating temperature range, small size and low power consumption make it an ideal choice for applications requiring long-term stability and accuracy in the frequency range. Additionally, its Flip-Flop circuit for frequency division, SSOP and self-test functionality provide further benefits that make it the perfect oscillator for a variety of applications.
