Programmable oscillators, also known as programmable frequency synthesizers, encourage precise frequency control without compromising stability and accuracy. The SIT9005ACL2D-30DL is a high-performance, programmable oscillator that can provide a wide range of outputs – ranging from 30 MHz to 150 MHz – for a variety of applications, such as radio frequency (RF) signal generation, clock and timing, datacom and telecommunications, industrial control and test and measurement.

This oscillator offers highly precise frequency range up to ±100 ppm. It also provides low power consumption and high level of harmonic suppression. In addition, the SIT9005ACL2D-30DL has low start-up current and short warm-up time, enabling quicker product turnarounds.

The SIT9005ACL2D-30DL programmable oscillator is a cost-effective solution for a wide range of applications. It integrates a frequency synthesizer, a phase-locked loop (PLL) and an output driver, providing synchronous division and broadband positive-edge clocking. The device uses a simple 3-wire (I2C) serial interface for programming and control, and can be programmed to generate several output frequencies.

This oscillator features a low phase noise and fast locking time, enabling quick LTE DSSS modulation. The SIT9005ACL2D-30DL is ideal for applications where low phase noise is important, such as in cellular base stations, systems that require synchronization, automotive radar and audio equipment.

This device is suitable for a variety of applications such as datacom and telecommunication, automotive, instrumentation, industrial control, consumer electronics and wireless, among other applications. It is available in both 14-pad QFP (quad flatpack) and NTQFN (narrowest thin quad flatpack no lead) packages.

The SIT9005ACL2D-30DL programmable oscillator is based on a voltage-controlled oscillator (VCO) in conjunction with a PLL. The VCO provides an LC oscillator that helps the oscillator provide high-frequency accuracy and stability. Frequency control is achieved by using a digital-controlled input to drive an internal divider. The PLL helps the oscillator reject input noise and maintain frequency accuracy over time and temperature changes.

The SIT9005ACL2D-30DL uses a 3-pin external crystal, in which the crystal frequency is divided by an on-chip frequency divider and provides the necessary reference for the VCO. The oscillator combines the reference signal and the VCO output using an analog loop filter, and updates the sampling output signal to achieve stability.

The device has a temperature-compensated internal voltage reference (TCVR) to help maintain a stable voltage supplied to the PLL controllers. The TCVR also helps the oscillator keep precise frequency control under temperature variations. The power supply of the SIT9005ACL2D-30D is 3.3 Vdc with a temperature range of -40 to +85 °C.

The SIT9005ACL2D-30DL is suitable for a variety of applications that require precise frequency control and stability. It has a low start-up current and short warm-up time, making it suitable for applications in which speed is important. The wide range of outputs and low power consumption make the oscillator ideal for datacom and telecommunication, automotive, instrumentation, industrial control, consumer electronics and wireless applications. Additionally, its highly accurate frequency range and low phase noise make the device well suited for cellular base stations, systems that require synchronization, automotive radars and audio equipment.
