    摘要: An electromagnetic interference (EMI) shield that increases the airflow through the EMI shield while preventing line-of-sight openings through the EMI shield. Two plates are coupled together. Each of the respective plates has a raised component with an aperture therethrough to provide a path through the plate. The raised component is preferably scoop-shaped with the aperture at one end and an opposite end tapering into the respective plate. At least a portion of one of the raised components overlaps at least a portion of the other of the raised components when the plates are coupled together to form a path through the plates, while the plates are coupled together. Line-of-sight openings through the plates, to an electronic device protected by the EMI shield, are at least partially prevented by the raised components.

    摘要: A method and circuit for generating a spread spectrum that will allow for precise control of the upper and lower frequencies of the fundamental to control the spread at the harmonics. The spread spectrum generation circuit of this invention includes a first clock producing a first frequency, a second clock producing a second frequency, the second frequency being set to a different frequency from the first frequency the second frequency being set to a different frequency from the first frequency. The circuit includes a phase locked loop circuit and the phased lock loop circuit includes a phase detector and the second clock. Following the phase locked loop circuit is a post divider that receives its input signal from the output of phase locked loop and then sends its output signal to an amplifier. The amplifier is used to amplify the input signal to produce an output signal that is the spread spectrum clock output for the circuit.
