Crystals are an essential component of electronic circuits and are used across a wide range of different industries. They are used to generate oscillating electrical signals of a fixed frequency, which are then used to regulate the functions and operations of electronic devices. The CA-301 49.3867M-K is a precision crystal oscillator that is commonly used for a variety of applications, including the PB FREE (Project Bureau Free) application field. This article will discuss the PB FREE application field in detail, as well as its working principle.

The PB FREE application field is an area of technology that focuses on the use of crystal oscillators as signal sources for various electronic devices. It is a system that allows the use of an external signal source instead of an internal source within a device. This allows for more reliable signal performance, improved signal integrity and increased system performance. Additionally, using an external signal source eliminates the need for additional filtering and shielding components, saving time and cost when creating new devices.

In the PB FREE application field, CA-301 49.3867M-K crystals are used to generate signals of a variable frequency, or a Stability Characteristic (SC), which defines the frequency of the crystal over a range of temperatures. This is important because electronic devices must work reliably across a wide range of temperatures, and their signal performance must remain consistent. The CA-301 49.3867M-K crystal is well-suited for this task due to its high accuracy and stability over a wide temperature range. The device can operate over a temperature range of -40°C to 105°C and has a frequency stability of ±3 ppm over the same temperature range.

The CA-301 49.3867M-K crystal also has a low power consumption, which makes it well-suited for use in battery-powered devices. Additionally, the crystal has a low profile, which allows for easy integration into a device’s design. The crystal also has a minimum output drive level of 8 mA, making it suitable for use in applications requiring high drive levels. Finally, the crystal has a compact footprint and can be used with top- and bottom-mounted configurations.

The working principles of the CA-301 49.3867M-K crystal can be divided into two main categories: mechanical and electrical. The mechanical principle involves the physical design of the crystal, which is determined by the configuration and size. The electrical aspect involves the connection of the crystal to an external circuit, which will determine the frequency of the signal. This is achieved by connecting the crystal to a resistor and capacitor network. When an electrical signal is applied to the crystal, the crystal will begin to oscillate with a fixed frequency, which is determined by the size of the crystal and the impedance of the connected network.

In conclusion, the CA-301 49.3867M-K crystal is an ideal choice for the PB FREE application field due to its high accuracy, stability and low power consumption. The mechanical and electrical principles of the crystal are well-suited for use in applications that require a reliable and stable frequency over a wide temperature range. Additionally, the device has a compact footprint, low profile and high output drive level, making it an ideal choice for these types of applications.
