PulseCore Introduces Drop-In EMI Reduction for FCC Compliance with Minimal Redesign

PulseCore Semiconductor Inc. announced what the company claims is the industry’s first spread-spectrum enabled EMI reduction devices that maintain synchronization between both clock and data paths. The Timing Safe™ line merges two technologies: zero delay clocking and spread-spectrum clock modulation for EMI reduction, with enhanced options for controlling spread margin and timing. The result is an EMI reduction IC that can be directly dropped in the path of an offending clock while maintaining the same phase and timing relationship with the synchronized data.

"The problem of excess EMI is growing exponentially with ever-shrinking converging technologies," said said Steve Kao, Vice President of Marketing and Sales for PulseCore Semiconductor. "PulseCore’s Timing Safe line targets excess EMI at the source allowing for last minute fixes and fast time to FCC compliance."

Timing Safe devices can be used in a general clock interface environment for a variety of consumer electronics and computing applications including memory subsystems, embedded platforms and numerous other interfaces. The flexibility of the architecture will allow PulseCore to extend the product line to support low power and higher frequency products, which will target other applications like cell phones, digital TVs and more.

PulseCore is initially offering two Timing Safe models. The ASM3P62300A/B/C are available in an 8-pin package, providing a single EMI-compliant phase-aligned output, and the ASM3P62300D/E are available in 16-pin packages with eight phase-aligned EMI-compliant outputs. Pin-to-pin skews are guaranteed to be less than 250 pS.

The ASM3P62300D/E also offer a Delay Control pin that can vary the input-to-output delay using a capacitive load. This can be used to achieve zero input-to-output phase shifts. These products target frequencies from 15 MHz to 50 MHz and offer selectable timing control and spread deviation. PulseCore Semiconductor offers commercial and industrial temperature grades, with standard tin-lead or full RoHS-compliant products.
