小数分频时钟倍频器

CS2501 是包含可编程锁相环路 (PLL) 的系统计时设备。混合模拟/数字 PLL 架构包括一个 Delta Sigma 小数分频模拟 PLL 和一个数字锁频环路 (FLL)。CS2501 可从稳定的时序参考时钟生成时钟。该设备可以在低至 50 Hz 的频率下从嘈杂的时钟参考生成低抖动时钟。内部振荡器可提供时序参考时钟，从而降低对外部组件的需求。CS2501 使用支持 I2C 和串行外设接口 (SPI) 操作模式的控制接口进行配置。CS2501 可由单个 1.8 V 或 3.3 V 电源供电。该设备将高性能与低功耗相结合。CS2501 采用商用级（-40°C 至 +85°C）的 10 引脚 • 高性能模拟/数字锁相环\n• 使用混合模拟/数字 PLL 实现分数时钟倍频和抖动减少 • 生成低抖动 6–75 MHz 时钟 (CLK_OUT)，与 50 Hz–30 MHz 低质量或间歇频率参考 (CLK_IN) 同步\n• 灵活的时序参考源 • 外部时钟、外部晶体或内置振荡器\n• 出色性能 • 高分辨率 PLL 比率 (1 PPM) \n• 40 psRMS 周期抖动\n• 使用内部参考，周期抖动为 35 psRMS\n• 间歇性输入产生的无故障时钟输出\n• I2C/SPI 控制端口\n• 可配置辅助时钟/状态输出\n• 要求的电路板空间最小 • 无外部模拟环路滤;
