Programmable Oscillators

Programmable oscillators, also known as configurable oscillators, offer flexibility and enhanced stability compared to a fixed-frequency oscillator. Programmable oscillators are used in a wide range of applications due to their ability to be adjusted for specific frequencies and/or operating conditions.

SIT9005ACR1D-XXDG Application Field and Working Principle

SIT9005ACR1D-XXDG programmable oscillators, manufactured by Silicon Timing UK, are small devices offering high stability and low-jitter performance for frequency synthesis and clock generation applications. The oscillators come in both low-voltage and low-power versions and can be configured with a wide range of frequency bands and output clock formats.

The SIT9005ACR1D-XXDG programmable oscillator is designed for high-precision timing applications and features a Silicon Timing UK designed monolithic frequency synthesizer and crystal oscillator with an active loop-filter system. The active loop-filter system helps to reduce the effects of temperature, voltage and aging on the oscillator. In addition, the oscillator incorporates a wide range of features including low-jitter, very low noise and excellent signal-to-noise ratio, making it ideal for critical applications.

The oscillator offers a broad range of frequencies from 3 MHz to 250 MHz. In terms of frequency band selection, the SIT9005ACR1D-XXDG supports the LVCMOS, LVDS, LVPCML, LVPECL, CML, LVHSTL, and HCSL level input formats. This allows for a wide variety of clock sources to be selected to suit the specific application. Additionally, the oscillator has a programmable enable/disable pin, which allows it to be used as a general-purpose clock source.

In terms of its primary application field, the SIT9005ACR1D-XXDG programmable oscillator is suitable for providing low-jitter clocks in networking and telecommunications equipment. The oscillator is also broadly used in instrumentation and industrial equipment, medical imaging and broadcast equipment, military applications and many other high-precision timing applications.

In terms of working principle, the oscillator operates in a “closed loop” mode in which an introduced voltage is compared to an internal reference voltage. The output of the comparison will cause an oscillator to switch from one stage to the next in a loop until an equilibrium of link between the two voltages is achieved. The oscillator will then oscillate at a frequency that depends on the values of the capacitor, inductor and resistor that form the elements of its closed loop.

The SIT9005ACR1D-XXDG is a versatile, low-cost and reliable programmable oscillator offering a wide selection of frequency bands and output clock formats, making it an ideal choice for a wide range of applications. Its frequency stability, low-jitter performance, high power efficiency and other features make it well suited for high-precision timing applications in a wide range of industries.
