Application of EPSON TSX-3225 series X1E000021xxxx17 crystal oscillator in car Bluetooth
Bluetooth module is a PCBA board that integrates Bluetooth function and is used for short-range wireless communication. It is divided into Bluetooth data module and Bluetooth voice module according to functions. Bluetooth module refers to the basic circuit set of chips integrated with Bluetooth function, which is used for wireless network communication. It can be roughly divided into three types: data transmission module, Bluetooth audio module, Bluetooth audio+data two in one module, etc. Generally, modules have the properties of semi-finished products, which are processed on the basis of chips to make subsequent applications simpler.
As a short-range wireless communication technology that replaces data cables, Bluetooth supports point-to-point and point to multipoint communication, wirelessly connecting various data and voice devices in homes or offices into a Pico net. Several Pico nets can also be further interconnected to form a distributed network (scatter net), enabling fast and convenient communication between these connected devices. This article introduces the implementation of Bluetooth interface on embedded digital signal processor OMAP5910. DSP samples analog signals and processes the digital signals after A/D conversion, which are transmitted to the receiving end through Bluetooth interface. Similarly, DSP performs D/A conversion on the digital signals received by Bluetooth to become analog signals.
The role of crystal oscillator in car Bluetooth
Crystal oscillator is a device used for wireless transmission of audio, communication, and data within the vehicle's Bluetooth module.
1. Provide a stable clock signal:
In Bluetooth communication, the crystal oscillator acts as a timer to provide a stable and accurate clock signal to the device. This clock signal will be used to synchronize the sending and receiving operations of Bluetooth devices to ensure smooth data transmission between devices. Through the clock signal provided by the crystal oscillator, Bluetooth devices can recognize and analyze the received data signal based on the synchronized clock.
2. Synchronous data processing:
The accuracy of crystal oscillators is crucial for the stability and reliability of Bluetooth communication. If the clock signal provided by the crystal oscillator is inaccurate, communication between devices may experience deviations or packet loss, affecting the quality and speed of communication.
Common frequency points for car Bluetooth: 16Mhz, 24Mhz, 26Mhz
Miniaturization and reliability: Bluetooth modules are divided into data Bluetooth modules, serial Bluetooth modules, voice Bluetooth modules, car Bluetooth modules, and 3225 passive crystal oscillators according to their applications. They are widely used in many Bluetooth devices, providing a stable and accurate frequency signal. This 3225 package is a small and common packaging type.
Passive crystal oscillators can resist the influence of external electromagnetic interference on car Bluetooth modules, provide clear and stable audio and data transmission, save energy, and extend battery life.
Recommend the application of the TSX-3225 series X1E000021xxxx17 passive crystal oscillator car Bluetooth device launched by EPSON, mainly reflected in its high precision and stability characteristics.
