YXC Programmable Differential Crystal Oscillator, Frequency 148.5MHz, LVDS Output, 5032 Package, Used in High-end Cameras
HD video conferencing camera is a device specially designed for real-time video communication and conferencing. It has the characteristics of high resolution, wide-angle lens, automatic adjustment function, etc. It is designed to provide clear and smooth video images of high-quality audio-visual communication and communication for remote conference participants.
Crystal oscillator plays an important role in high-definition video conferencing cameras, mainly reflected in the following aspects:
1) Clock synchronization: High-definition video conferencing cameras require precise clock synchronization to ensure the synchronization of the collection, encoding, transmission and display of video frames. The crystal oscillator provides a stable clock signal, which is used to synchronize the work of various modules inside the camera to ensure the continuity and accuracy of the video stream.
2) Video frame rate control: The output video of a high-definition video conferencing camera is usually transmitted and displayed at a certain frame rate, such as 30 frames/second or 60 frames/second. The clock signal provided by the crystal oscillator is used to control the frame rate of video capture and encoding to ensure the stability and smoothness of the output video stream.
3) Image processing synchronization: The image processor inside the camera usually requires a precise clock signal to perform image enhancement, white balance, color correction and other processing to improve video quality. The clock signal provided by the crystal oscillator is used to synchronize the work of the image processor to ensure that the image quality reaches the high-definition level.
4) Data transmission timing: The camera transmits video data to other devices or networks through various interfaces (such as USB, HDMI, Ethernet, etc.). The clock signal of the crystal oscillator is also used to control the data transmission timing to ensure accurate transmission and reception of data.
Generally speaking, the application of crystal oscillators in high-definition video conferencing cameras is mainly to provide a stable clock signal to synchronize the work of each module to ensure the accuracy and smoothness of video collection, processing, transmission and display, thereby ensuring high-quality Video conferencing experience.
The active crystal oscillator YSO230LR series launched by YXC is made of OB1LIB112-148.5M. The following are the typical parameters of OB1LIB112-148.5M and its application characteristics in high-end cameras:
