Programmable oscillators are electronic components that generate periodic, precision digital clocks. They provide a means to mix and match frequencies, without the need to build separate application-specific clock sources. SIT9005ACL1G-XXDP programmable oscillators are wide-ranging components developed for use in many industries including communication, automotive, industrial, medical and military.

The SIT9005ACL1G-XXDP programmable oscillator offers a frequency range of 10 kHz - 5 GHz, with an excellent harmonic ratio and phase noise performance. Its primary benefit over conventional oscillators is its flexibility; eliminating the need for multiple components when a variety of frequencies are needed. The oscillator helps save time, money and board space. Furthermore, the SIT9005ACL1G-XXDP supports both serial (SERDES) and dual port (DSP) interfaces.

The SIT9005ACL1G-XXDP also provides a digital control interface, which allows the end user to change frequency, phase, duty cycle and other parameters. This same interface is used to monitor status and retrieve performance data, with programmable read back control. This programmable oscillator integrates both a high frequency voltage controlled oscillator (VCO) and low frequency phase locked loop (PLL) circuitry within the same package.

The integral PLL allows the SIT9005ACL1G-XXDP to generate very precise frequency modulation over a wide dynamic range. PLLs also ensure that component and environmental signal quality remains consistent over the entire operating range. Accurate signal timing will always be maintained, providing higher levels of system reliability.

The VCO section of the SIT9005ACL1G-XXDP offers greater frequency flexibility. By adjusting supply voltages and/or control currents, the oscillator can be tuned over a wide frequency range (50MHz - 5 GHz). With the VCO, it is possible to generate and lock onto specific frequencies, while preserving the frequency accuracy of the oscillator.

When the low phase noise and fast synthesizing are combined with the high frequency range and phase accuracy of the SIT9005ACL1G-XXDP, superior system performance can be achieved for a variety of applications. Its wide operating temperature range of -40°C to +85°C makes the oscillator ideal for both telecommunications and military applications.

The SIT9005ACL1G-XXDP is a low-jitter, high-performance oscillator suitable for a broad range of applications including communications, medical imaging, instrumentation, automotive, and industrial automation. Due to its excellent Phase Noise and harmonic ratio performance, it provides an excellent platform for clock generation and jitter attenuation. It is a very cost-effective timing solution, due to its programmability, which allows it to replace multiple discrete crystals.
