CS325H-26.000MEDQ-UT Application Field and Working Principle

The CS325H-26.000MEDQ-UT crystal oscillator is a miniature, active crystal oscillator module designed to generate a stable, accurate, and low phase noise clock signal in a very small package. SiTime Inc., a leading volumetric quartz crystal oscillator (QCO) supplier, developed the CS325H-26.000MEDQ-UT oscillator to provide high clock stability and precision in a range of applications.

The CS325H-26.000MEDQ-UT is a quartz crystal oscillator module with an integrated circuit adapted for applications that require a stable, low phase noise clock signal with a frequency accuracy of ±20ppm or better. The module is available in a tiny 4.47mm x 2.74mm x 0.92mm 20-pad surface mount package, making it an attractive choice for portable designs and applications with limited space.

The CS325H-26.000MEDQ-UT features a quartz crystal in a temperature-compensating oven. The module also contains a programmable, low power, low jitter differential output buffer. The output buffer is designed to provide ±0.50V to ±2.8V DC output voltage levels, depending on the application. The output frequency is precisely adjustable over a wide range for applications that require a frequency ramp or specific frequencies.

The CS325H-26.000MEDQ-UT integrates temperature and vibration compensation to minimize output frequency variability over time. A temperature coefficient of 0.17 ppm from -40° to +85°C makes the CS325H-26.000MEDQ-UT suitable for applications with a wide temperature range. The module also offers a high shock and vibration tolerance, making it a good fit for automotive, industrial, and aerospace applications.

The CS325H-26.000MEDQ-UT is a low-cost and low-power quartz crystal oscillator offering reliable performance at high temperatures and high shock and vibration levels. The module features a low phase noise of -125dBc/Hz at 10kHz offset, a stability of ±20ppm over -40°C to +85°C, and an excellent sinusoidal waveform. The CS325H-26.000MEDQ-UT crystal oscillator is an ideal choice for demanding applications where size, cost, and low power consumption are important considerations.
