摘要： The present invention provides a SATA cable with light display feature, which is mainly used for the SATA cables for computer host and their peripheral devices. With the light display capability, the connection readiness status and the signal transmission conditions can be easily detected via the pins on the SATA cable. The realization technique used by the present invention is adding the LED lights and the control pins inlayed at the two plug-in ends of the SATA cable. When the two plug-in ends of the SATA cable are both connected and ready, or there is data transmission going on, the control pins automatically turn on the LED lights to indicate the ON/ACTIVE connection status/condition.

摘要： An apparatus and method for automatically switching between USB host and device is provided. In a device with a USB interface, the present invention automatically switches between a USB host and USB device by detecting the handshake protocol of the D+ and D− pins of the USB interface. The apparatus for automatically switching between USB host and device includes ah host mode element, a device mode element, a random auto-switcher, and a detection element. The random auto-switcher switches the connection to the host mode element or the device mode element at random time. The detection element monitors the handshake protocol of the D+ and D− pins of USB interface and the external USB-interface device to determine whether the host mode or the device mode is in use. When the present invention detects the external USB-interfaced device is a host, the present invention switches to become a USB device. Similarly, when the present invention detects the external USB-interfaced device is a USB device, the present invention switches to become a USB host.

摘要： A phase-locked loop (PLL) with novel phase detection mechanism is provided, including a phase frequency detector (PFD), a controller, a digital-to-analog (D2A) module, and a voltage-controlled oscillator/current-controlled oscillator (VCO/ICO), wherein PFD has a reference signal input and an input from output signal of the VCO/ICO and is connected to the controller, the controller is then further connected to D2A module, D2A module converts the control signal from the controller into an analog voltage to control the frequency and phase of VCO/ICO. It is worth noting that the PFD of the present invention has a novel phase detection mechanism so that the phase detection does not rely on edge alignment. In addition, the novel phase detection mechanism also allows flexible reference signal input, as opposed to the aforementioned fixed external source, such as, a crystal.
