【Applications】Yangxing crystal launched 3225 package size 24MHz passive crystal for network cameras, room temperature frequency difference ± 10ppm

Network camera, also called IPC, is a combination of traditional cameras and network technology produced by a new generation of cameras. Network cameras can be formed with routers, switches, NVR (Network Video Recorder) and other devices into a surveillance system.

The hardware composition of the network camera generally includes lenses, image sensors, sound sensors, signal processors, analog/digital converters, encoding chip, master control chip, network and control interfaces and other components. Light through the lens into the sensor, and then converted to digital signals by the built-in signal processor for pre-processing, the processed digital signals by the encoding compression chip for encoding and compression, and finally through the network interface sent to the network for transmission.

The customer's IP Camera (IPC) project requires the use of a passive crystal oscillator with 24MHz, 12pF load, 3225 package, and the final solution adopts YXC's YSX321 series, with the material number of XL2OI-111-24MHZ, and its specifications are as follows:

The product features and advantages of XL2OI-111-24MHZ are as follows:

①High precision, frequency deviation ±10ppm at room temperature 25℃, can provide good and stable clock signal for monitoring system;

②Industrial grade temperature -40~﹢85℃, can be applied to indoor, outdoor and other different environmental needs;

③3225 mainstream package size, cost-effective.
