The smart home security kit consists of a smart gateway relay, smart sensors and switch devices. The smart gateway relay integrates a WIFI module and a zigbee module, connects to the Internet cloud through the WIFI module, and connects to the smart sensor and smart switch through the zigbee module To realize the reporting of smart sensor data and the control of smart switches, the designer uses the EFR32MG21 wireless module, of which 16MHz uses the Hongxing crystal oscillator HCX-3FB series crystal oscillator E3FB16E000001E to ensure the stable operation of the product's radio frequency function. The EFR32MG21 wireless module requires one The external clock source provides a precise clock to ensure the normal operation of the module. The load capacitance and frequency deviation of the crystal oscillator are required to meet the specifications. The frequency of this Hongxing E3FB16E000001E crystal oscillator is 16MHz, the frequency error is ±10ppm, the load capacitance is 9PF, and the frequency and frequency error are both Meet the requirements of different electronic products.

E3FB16E000001E's crystal load capacitance can be adjusted and matched through the EFR32MG21 built-in adjustable capacitor library, without external load capacitance, low frequency aging rate, E3FB16E000001E has a lower frequency aging rate, frequency The aging rate is ±1ppm/year, which can ensure the longer service life of the EFR32MG21 wireless module. The driving power of E3FB16E000001E does not exceed 100μW RF reference, which is easier to achieve the low power consumption requirements of the module compared with the active crystal. Small package, E3FB16E000001E package size is only 3.2x2.5mm, can save PCB layout space wireless module, the module allows more flexibility in the design space, HOSONIC Hongxing crystal E3FB16E000001E and EFR32MG21 master mix use, no external load capacitance, a built-in EFR32MG21 To adjust the capacitor library, you can set the internal adjustable capacitor by setting the value of the CTUNE register.
HOSONIC Hongxing Jing Zhen was founded in 1994, has a high reputation in Taiwan-based crystal brand, the company in 1991 and put into crystal, crystal, crystal active in Taiwan, add a linker script development, and manufacturing vibration, in 1991 began to enter the mainland China Expansion of production bases, so far with four production bases, nine marketing and FAE bases and ten marketing representative offices, Hongxing Electronics has become one of the world's important manufacturers of quartz frequency control components, and is committed to plug-in (DIP) ) And surface mount (SMD) quartz crystal products research and development, design, production and marketing, Hongxing is committed to providing customers with the best quality, service and value, focusing on professional innovation and encouraging employees to cooperate and grow actively Attitude keeps pace with the times.
