*Extended high frequency power decoupling is recommended (see test circuit for minimum
recommendation). To ensure optimal performance, do not route RF traces beneath the
package.

当今的计算机外部设备，都在追求高速度和高通用性。为了满足用户的需求，以Intel为首的七家公司于1994年推出了USB（Universal Serial Bus，通用串行总线）总线协议，专用于低、中速的计算机外设。目前，USB端口已成为微机主板的标准端口；而在不久的将来，所有的微机外设，包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等，都将通过USB与主机相连。

LED 是light emitting diode (发光二极管)的缩写,是一种由半导体技术制成的电光源。LED的核心部分是由P型半导体和N型半导体组成的晶片,在P型半导体和N型半导体之间有一个过渡层,称为P2N结。在正向导通时,半导体中的多数载流子和少数载流子复合,释放出的能量以光子或部分以光子的形式发射出来,大量的光子形成光子流,即发光。P2N结加反向电压时,少数载流子难以注入,故不发...[详细]
