SM840001

SM840001 106.25MHz Ultra-Low Jitter Clock Synthesizer General Description 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 optimized performance. This yields an overall improved Bit Error Rate (BER) and improved waveform integrity. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
