Programmable oscillators are essential components for a wide range of different applications and systems. The SIT1602ACL7-25S is one such oscillator and is designed for use in environments where reliability, accuracy and low power consumption is essential. This purpose-built oscillator incorporates the latest advancements in quartz crystal technology and is suitable for use in embedded systems, telecom platforms, computers, networking applications and other fields where accuracy is paramount. The device offers a wide range of benefits, including a very low frequency stability of 0.25ppm over the operating temperature range and an operational temperature range of -40C to +85C. The device also features a temperature compensated oscillator (TCXO) which allows it to achieve very high performance over its operating temperature range.

The main working principle of the SIT1602ACL7-25S can be split into two main parts, the Receiver and the Transmitter. The Receiver is the part of the device that collects external signals from the environment, such as the radio frequency (RF) or microwave signals. The Transmitter acts as the engine of the device and is responsible for translating the external signals into the desired output – for example, the oscillating frequency.

The Receiver is composed of a discrete circuit comprised of an input buffer stage, a frequency divider, a phase-lock loop, and a sample-and-hold circuit. The input buffer stage ensures that the receiver is able to accurately detect and amplify incoming signals. The frequency divider then divides the input signal frequency by the desired programmable division ratio to generate a reference frequency for the phase-lock loop. The phase-lock loop then locks the reference frequency to the incoming signal to track and maintain a steady frequency output. The sample-and-hold circuit then holds the output frequency at a constant level by continuously comparing the input signal to the reference frequency.

The Transmitter is composed of a discrete circuit comprised of an output buffer stage, a voltage controlled oscillator (VCO), a low-noise amplifier, and a temperature compensated oscillator (TCXO). The output buffer stage amplifies the output signal to a desired level. The voltage controlled oscillator (VCO) is used to generate an output signal of a specified frequency, which is then passed through the low-noise amplifier to reduce any noise and distortion in the output signal. The temperature compensated oscillator (TCXO) is used to maintain a very high performance over the operating temperature range by compensating changes in temperature.

The SIT1602ACL7-25S is a highly reliable and accurate Programmable Oscillator, and is perfectly suited for applications that require both low power consumption and accuracy. The device features a low frequency stability of 0.25ppm and an operational temperature range of -40C to +85C. It also has a temperature compensated oscillator (TCXO) which ensures a high level of performance and reliability over the operating temperature range. In addition, the device is perfect for use in embedded systems, telecom platforms, computers, networking applications, and other applications where accuracy is paramount.
