如果在調諧器或電視機附近使用本機或任何其他使用微處理器的電子設備,則可能會產生圖像的噪聲或干擾。如果發生這種情況,請采取以下步驟將本機安裝在盡可能遠離調諧器或T的地方。遠離調諧器或T,遠離本機的電源線和輸入/輸出連接電纜。尤其在使用室內天線或300歐姆饋線。我們建議使用室外天線和75 Q / ohm同軸電纜noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables
The JW? 7805 is a low noise low-dropout (LDO) voltage regulator with enable function that operates from 1.8V to 5.5V. It provides up to 300mA of output current and offers low-power operation in miniaturized packaging. JW7805 supports fixed output voltage 0.9V, 1.0V, 1.05V, 1.1V,1.2V, 1.3V, 1.35V, 1.5V, 1.8V, 1.85V, 2.1V, 2.2V, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V,3.1V, 3.3V, 3.6V, 4.2V, 4.4V and 5.0V. The features of low quiescent current as low as 6uA and almost zero disable current are ideal for powering the battery equipment. JW7805’s low output noise and high PSRR are also friendly to RF systems.
