摘要: An integrated circuit is adapted for dual use in three different ways: 1) it is powered by either of two different low or high voltage sources; 2) it may be connected to the IC package voltage reference pin in two different ways, using either an on-chip internal resistor or an in-package external resistor to limit the voltage/current to the IC; 3) the ESD structures are used not only for their well-known circuit protection function, but also as a conductive path for the high voltage operating source.

摘要: A method for applying spread spectrum noise reduction techniques to USB specifically USB2.0 communications systems includes the step of generating a base (seed) frequency for the USB system, modulating the base (seed) frequency with a spread spectrum (SS) characteristic, and utilizing (as-is, not modified) the existing ASIC that multiplying the now modulated base (seed) frequency to generate the USB standard frequency signaling rate of 480 MHz with the SS characteristic within the USB standard specification for frequency deviation.
