Crystals: CSA309-15.000MABJ-UB Application Field and Working Principle

Crystals are widely used in consumer electronics such as Bluetooth, Wi-Fi and wireless networking equipment, personal communication systems, cellular, automotive and consumer electronics. Crystals are essential components of any product that uses radio frequency (RF) technology, and they are used to generate a steady reference frequency that can be used to make a precision transmission. CSA309-15.000MABJ-UB is an example of a crystal used in consumer electronics.

CSA309-15.000MABJ-UB was introduced by Epson as an ultra-small, low-cost and high-performance surface mount crystal oscillator that has been designed for use in consumer electronics. It is a Type B XTAL (crystal oscillator) with an optimal frequency range of 15-25 MHz, and is designed for operation at a supply voltage of 3.3V. The main features of the CSA309-15.000MABJ-UB are its low power consumption, excellent stability and excellent shock and vibration resistance.

The CSA309-15.000MABJ-UB crystal oscillator works by creating an alternating current (AC) output that can be used as a reference frequency generator. The quartz crystal oscillator has two input pins and four output pins. These include two ground pins, two operating voltage pins and two input pins; the operating voltage pin must be supplied with 3.3V to operate the oscillator.

The crystal oscillator has a Quartz resonator at its core, and this is made up of two plates which vibrate at a certain frequency dictated by their physical parameters. When the quartz oscillator is driven with an alternating current, it is affected by vibration, temperature and other external influences which can cause a change in the frequency of the output signal. Takurō Ishiwatari, who worked at Epson’s research laboratories, developed the CSA309-15.000MABJ-UB and managed to reduce the temperature coefficient, frequency drift and shock and vibration resistance of the crystal oscillator to a minimum.

The main application area of CSA309-15.000MABJ-UB is consumer electronics, such as personal communication devices, Wi-Fi and Bluetooth enabled devices, consumer electronics and automotive equipment, among other applications. It is an ideal solution for consumer electronics with compact designs, high precision timing and low-power consumption requirements. The CSA309-15.000MABJ-UB can also be used to manufacture products that have both consumer and industrial applications.

In summary, the CSA309-15.000MABJ-UB is an ultra-small, low-cost and high-performance surface mount crystal oscillator that has been designed for use in consumer electronics. The design by Takurō Ishiwatari has reduced the temperature coefficient, frequency drift and shock and vibration resistance of the crystal oscillator, while also providing an AC output that is suitable for use as a reference frequency generator. The main application area of CSA309-15.000MABJ-UB is consumer electronics, such as personal communication devices, Wi-Fi and Bluetooth enabled devices, consumer electronics and automotive equipment.
