Introduction to Programmable Oscillators

Programmable oscillators are specialized types of oscillators used for precise frequency control, typically for sampling-based digital signal processing. These oscillators provide a wide range of adjustable frequency, phase, gain and other parameters and can be used in virtually any application where frequency stability and precision control is required.

SIT9005ACL1G-30SM Application Field and Working Principle

SIT9005ACL1G-30SM is a programmable oscillator specifically manufactured by SIT Corporation which has wide range of applications due to its precisely adjustable frequency and parameters. It features a 0.8mm x 0.8mm x 0.34mm package size, with a frequency range between 10MHz to 66MHz and minimal phase-noise of -116dBc/Hz at 10KHz offset.

To understand the working principle of this oscillator, it is important to first understand the concept of a quartz oscillator. A quartz oscillator essentially contains two quartz crystals, one that vibrates and one that operates as a feedback loop for the oscillator. When an electric current is applied to the oscillator, the crystal vibrates at an almost fixed frequency determined by the crystal’s specific mechanical properties.

The SIT9005ACL1GW-30SM programmable oscillator adopts this same principle, but improves it by using a digital signal processing technique. In this technique, precise frequency adjustments are possible due to the ability of the signal from the quartz crystal to be amplified and the precise frequency is set by integrated next-generation signal processing logic.

It is this precise signal processing logic that allows SIT9005ACL1GW-30SM to be so adaptable to a variety of applications. With an adjustable frequency range of 10MHz to 66MHz, this oscillator can be used for high-speed Ethernet, Wi-Fi, Bluetooth, and USB communications, as well as military and aerospace systems, industrial wireless applications, test equipment, and high-speed datacomm.

In addition, this programmable oscillator stands out when compared to traditional quartz-based oscillators due to its minimized phase-noise, reaching -116dBc/Hz at 10KHz offset and its low power consumption of just 5mW. With its tiny 0.8mm x 0.8mm x 0.34mm package size, this oscillator can be used for size-constrained designs.

Conclusion

With its precise adjustable frequency, adjustable parameters, minimized phase-noise and minimal power consumption, SIT9005ACL1GW-30SM is an excellent choice when it comes to programmable oscillators. This oscillator can be used in a variety of applications from high-speed Ethernet to industrial wireless and aerospace systems, enabling a precise and reliable frequency to be generated. Moreover, its small package size makes it ideal for size-constrained designs.
