SM840004-11数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The SM840004-11 clock synthesizer was designed for Gigabit Ethernet applications. The device design is optimized for 62.5MHz and 125MHz using a standard 25MHz fundamental parallel resonant crystal, with unparalleled stability and accuracy over the full operating range, and provides an easy fit for Jitter and Phase Noise standards for these high performance interfaces.The SM840004-11 design includes a unique power reduction methodology, along with a patented RotaryWave s™ 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.
