Programmable oscillators have become increasingly useful and important across a variety of applications. From the military, to test-and-measurement applications, and consumer audio devices, an oscillator is used to control the frequency of an output signal over a frequency range. In each case, a higher degree of frequency accuracy and stability is usually desired. To accomplish this, programmable oscillators such as the SIT9005ACB1D-XXDP, have become a required resource.

The SIT9005ACB1D-XXDP is a low jitter, high performance programmable oscillator that utilizes Phase-Locked Loop (PLL) technology, allowing it to provide improved frequency accuracy and programmability. It is designed to accommodate a wide range of customer needs from wireline and wireless communication to low power and computing applications. The SIT9005ACB1D-XXDP has a frequency range of 15 to 387 MHz and a voltage range of 1.8 to 3.3V. The device also features a low jitter profile with a jitter of 1.4 ps RMS typically, and provides high frequency stability for applications.

The SIT9005ACB1D-XXDP also has a programmable reference input to allow users to customize their device. This feature makes it particularly useful for a variety of customer requirements, including phase-locked loop (PLL) synchronization and frequency tuning applications. The programmable reference feature also assists in keeping the frequency accuracies of the oscillator at their high performance level.

The SIT9005ACB1D-XXDP uses a simple SPI or I²C dedicated control pin to set the oscillator frequency, allowing users to program their desired frequency in a number of different parameters. Additionally, the device features differential PECL outputs in CLK+, CLK−, CLK1+ and CLK1−. The differential signal makes the device more resistant to electromagnetic interference (EMI), which is important for consumers. The device also has an output buffer signal that can be programmed with various output drive strength settings including VL, L, H, and UL.

The SIT9005ACB1D-XXDP is well suited for a wide range of applications, from portable electronics to automotive environments. The device is designed to be used in products such as Bluetooth, routers, set-top boxes, portable media players, cellular phones, automotive systems, and many other similar applications. It is also well suited for other applications where low jitter, high frequency accuracy and stability is needed.

The working principle of the SIT9005ACB1D-XXDP is based on the principle of a phase-locked loop. The device uses the characteristics of the oscillator and the reference input to generate a frequency signal. When a signal is introduced at the reference input, the oscillator is tuned according to the signal and starts to oscillate at the same frequency. The device then utilizes the on-chip control logic to amplify the output and create the desired signal. The signal is then propagated to the output buffer and fed to the external load.

In conclusion, the SIT9005ACB1D-XXDP is a reliable and flexible programmable oscillator designed for a wide range of applications. With its high accuracy and stability, low jitter, and programmability, the device is ideal for a range of customers seeking a reliable and high-performance programmable oscillator. Its differential signal output makes it resistant to EMI, and its programmable reference input ensures that the device maintains its high performance for customers.
