SM840051 10 Gigabit Ethernet Ultra-Low Jitter Clock Synthesizer General Description The SM840051 clock synthesizer was designed for Ethernet standards. The SM840051 is optimized for 77.76, 78.125, 80.56, 155.52, 156.25, and 161.13MHz, using a crystal at 1/8th the output frequency. The SM840051 includes a unique power reduction methodology, along with a patented RotaryWave™ 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. Power supplies of either 3.3V or 2.5V are supported, with superior jitter and phase noise performance. An FSEL pin supports 4x or 8x multiplication of the crystal frequency. The SM840051 provides ultra-low jitter, and consumes low power. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
