Suntsu Quartz Crystals are available in through-hole or surface-mount packaging with many sizes to choose from. Pick out a standard part number from the data sheets below or contact our sales team to request any custom parameters that you desire and we will design to your specific needs.
Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress. They are the most common type of piezoelectric resonator used today.

A Crystal Oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.
Suntsu VCXO’s are available in through-hole or surface-mount packaging. We offer a wide frequency range and many different voltages and logic options.

Voltage-Controlled Crystal Oscillators are used when the frequency of operation needs to be adjusted. The frequency of a voltage-controlled crystal oscillator can be varied typically by a hundred parts per million (ppm) because the high Q factor of the crystals allows “pulling” over a range of frequencies.
Reasons for using a VCXO are to adjust the output frequency to match (or perhaps be some exact multiple of) an accurate external reference or where the oscillator drives equipment that may generate radio-frequency interference (adding a varying voltage to its control input can disperse the interference spectrum to make it less objectionable).
Suntsu TCXO’s and VCTCXO’s are available in through-hole or surface-mount packaging with many sizes to choose from. We offer many different voltages and can provide parts with Stratum 3 compliancy. Pick out a standard part number from the data sheets listed below or contact our sales team to request any custom parameters that you may require and we will design to your specific needs.
Temperature-Compensated Crystal Oscillators use sampling techniques to correct the temperature deficiencies of a crystal oscillator circuit, its package, and its environment. Typically the correction techniques involve the physical and electrical characterization of the motional inductance and terminal capacitance of the crystal blank. The knowledge of which is used to create a correction polynomial, or algorithm, which in turn is implemented in circuit blocks and maintains better stabilities than standard oscillators.
Suntsu Electronics has designed custom TXCOs and OCXOs specially for Stratum 3 and Stratum 3E. Stratum 3 TCXOs come in in small, ceramic SMD package delivered via Tape and reel. The Stratum 3 clock serves to track input under normal operating conditions, but at a wider range than Stratum 2. Stratum 3E OCXOs have been optimized for IEEE-1855v2 timing applications such as network synchronization clocks, coherent optic clocks, and jitter cleaners.
OCXO’s are available in through-hole packaging with many sizes to choose from. We offer many different voltage and logic options and can provide parts with ±800ppt stability. Pick out a standard part number from the data sheets listed below or contact our sales team to request any custom parameters that you desire and we will design to your specific needs.
Oven-Controlled Crystal Oscillators use temperature-controlled chambers to keep the quartz crystal inside the oscillator at a constant temperature in order to prevent changes in the frequency due to variations in the external temperature. OCXO’s are typically used to control the frequency of radio transmitters, cellular base stations, military communications equipment, and in measurement applications where the highest frequency stability possible from crystals is needed.
Suntsu RTC (Real Time Clock) oscillator has the built-in TCXO(Temperature Compensated Crystal Oscillator) and temperature sensor with supporting low power consumption and high stability. RTC also features a miniature size of 3.2mm X 2.5mm surface-mount package with providing excellent real-time clock function, I2C interface, and backup battery switchover function.
Suntsu Rubidium Oscillators are available in an array of packages to choose from. Pick out a standard part number from the data sheets listed below or contact our sales team to request any custom parameters that you desire and we will design to your specific needs.
Rubidium oscillators are a type of atomic clock and are the most accurate time standards known and are used as time distribution services to control things such as telecommunications infrastructure, TV broadcasts, and global navigation satellite systems (GPS).
