Abstract: The genus of apparatus according to the teachings of the invention is characterized by use of a heat conducting elastomer which is compressed between an integrated circuit and a surface of a chassis made of heat conducting material such as Aluminum. The elastomer conducts heat from the integrated circuit to the surface of the chassis where it warms the entire chassis and is radiated to the ambient and removed by convection cooling. Since the chassis provides a much greater radiating and convection cooling surface, cooling of the integrated circuit is enhanced.

Abstract: A synthesized jitter generator employing a novel digital architecture is provided. The apparatus provides period synthesis and controlled sinusoidal and non-sinusoidal jitter modulation functions of a square wave provided at its output. The architecture consists of a coupling of an N+M bit digital accumulator and an N bit synchronous counter to an N bit magnitude compare circuit. The output of the magnitude compare strobes the accumulator when the two inputs are equal in magnitude causing the accumulator to increment synchronously. The output of the magnitude compare is also a digital waveform whose average period is precisely defined by the input word to the accumulator.
