Crystal

Crystal resonator, is a passive component which using the quartz piezoelectricity. It need outside voltage input, and then supplies signal to IC and lets the moduals work. Full size range for your choice, such as SMD 5032, 3225, 2520, 2016, 1612, 1210.
Oscillator

Oscillator offers better energy efficient solution, and better phase noise. It has higher precision and higher stability. Full size range for your choice, OSC 7050, 5032, 3225, 2520, 2016, 1612, 1008, with frequecy from 32.768KHz, to 156.25MHz.
Tuning Fork - 32.768KHz

A 2 pads crystal resonator, only output frequecny of 32.768KHz, which is a passive component for clock timing devices. Full size for your choice, 3.2 x 1.5, 2.0 x 1.2, 1.6 x 1.0, with different load capacity for your circut matching, such as 6pF, 7pF, 9pF, 12.5pF.
Temperature Compensated Crystal Oscillator - TCXO

Temperature compensated crystal oscillator has high-precision and high-stability, within certain temperature ranges. Frequecy is compensated during production under -40~85℃, to have a ultra high precision oscillator, TC < ±0.5ppm. Different size for your choice, TCXO 3225, 2520, 2016, 1612.
Differential XO

Differential oscillators output with modes of LVDS, LVPECL, HCSL. On optical networking equipments, it leads ultra high stability and clear signals. Full size range for your choice, 7050, 5032, 3225, 2520, 2016, with frequency range high to 156.25MHz.
Temperature Sensing crystal

Temperature sensing crystal combines with a thermistor, making it sensitive to the temperature. IC will adjust the frequency change with temperature variations, getting temperature signal from the thermistor. Full size range for your choice, TSX 2520, 2016, 1612, with frequency of 19.2MHz, 26MHz, 38.4MHz, 76.8MHz certified by Qualcomm, MTK, ASR, etc.
Real Time Clock

Real time clock supplies functions of alarm, calendar, automatic calibration timing to the satellite, for timing clock devices. It also supplies ultra low energy for devices to keep timing function more than 10 years. Size ready for your choice is 3225, output frequency is 32.768KHz.
