SM840001 Datasheet

106.25mhz Ultra-low Jitter Clock Synthesizer

Manufacturer: Micrel Semiconductor (now Microchip Technology)

SM840001 Overview

The SM840001 synthesizer series were designed for Fibre Channel applications. The device design is optimized for 106.25MHz or 212.5MHz using a 26.5625MHz fundamental parallel resonant crystal, with stability and accuracy over the full operating range. The SM840001 includes a unique power reduction methodology, along with a patented RotaryWaveTM architecture, that provides a stable clock with very low noise for...
