Programmable Oscillators are electronic components used to generate repeating waveforms at a selection of frequencies, typically in the radio frequency (RF), microwave, and millimeter wave bands. They consist of an oscillator circuit, a digital-to-analog converter (DAC), and a digital control logic circuit, and are available in various packages such as surface-mounted (SMT), through-hole, chip carrier, and plastic modules. Depending on the design of the oscillator, these components can also be used for digital signal processing (DSP) applications. The SIT9005ACR1G-33EB Programmable Oscillator is a highly accurate voltage controlled oscillator (VCO) designed for frequency control in applications such as data communications, clock and timing control, optical networking, and global positioning systems (GPS).

The SIT9005ACR1G-33EB offers ultra-smooth tuning characteristics, enabling designers to reduce circuit complexity while maintaining accurate frequency control. The oscillator features a low EMI noise floor, increased operating temperature range and a wide tuning range of 10.5 to 600 MHz with excellent linearity. On-board temperature compensation improves overall frequency accuracy and stability. Due to its low power consumption, the SIT9005ACR1G-33EB is ideal for small, low-power applications that require accurate and stable frequency control.

The SIT9005ACR1G-33EB Programmable Oscillator integrates a fully-integrated, dual-core Crystal Oscillator circuit with CMOS digital control logic on a single chip. The Crystal Oscillator circuit consists of a basic oscillator circuit, a voltage-controlled oscillator (VCO) circuit, and a noise-canceling circuit. The basic oscillator circuit is designed to generate a stable, accurate frequency by combining a quartz crystal resonator and external components. The voltage-controlled oscillator circuit then controls the frequency of this basic oscillator circuit. Finally, the noise-canceling circuit is used to reduce noise emission from the oscillator.

The digital control logic on the SIT9005ACR1G-33EB includes a low-power, two-channel DAC and an on-chip frequency control processor. The two-channel DAC is used to encode the frequency of the crystal oscillator. The frequency control processor then compares the input signal to a reference value, and uses the results to adjust the frequency of the crystal oscillator. The digital control logic also supports several operating modes, including shutdown, standby, and soft-start.

The SIT9005ACR1G-33EB Programmable Oscillator can be used in a variety of applications. Common uses include frequency-critical systems such as digital communications, telecom, land mobile radio and satellite systems, as well as clock and timing references for precise data processing and other sensitive operations. The SIT9005ACR1G-33EB can also be used in navigation systems and data processing systems, providing reliable and accurate timing references for precise data processing and other sensitive operations. Additionally, the programmable oscillator can be used in antennas, antennas amplifiers, modulation systems, and radar systems.

In conclusion, the SIT9005ACR1G-33EB Programmable Oscillator is an ideal solution for frequency control in a variety of applications due to its high accuracy and stability, low power consumption, and wide tuning range. It offers excellent linearity and a low EMI noise floor, enabling designers to reduce circuit complexity while maintaining accurate frequency control. With its low power consumption and wide operating temperature range, the SIT9005ACR1G-33EB is also an ideal choice for small, low-power applications that require high accuracy and reliable frequency control.
