AD9577

带双路PLL、扩频和余量微调功能的时钟发生器

AD9577既提供一个多路输出时钟发生器功能，又带有两个片上锁相环内核PLL1和PLL2，专门针对网络时钟应用而优化。PLL设计基于ADI公司成熟的高性能、低抖动频率合成器产品系列，确保实现较高的网络性能。PLL具有I2C 可编程输出频率和格式。小数N分频PLL可支持扩频时钟功能，降低EMI辐射的峰值功率。两个PLL均可支持频率余量微调功能。 第一个整数N分频PLL部分(PLL1)由一个鉴频鉴相器(PFD)、一个电荷泵(CP)、一个低噪声电压控制振荡器(VCO)、一个可编程反馈分频器和两个独立可编程输出分频器组成。通过将外部晶振或基准时钟连接至REFCLK引脚，可将最高达637.5 ; • 完全集成双路PLL/VCO内核 \n\n• 1个整数N分频和1个小数N分频PLL \n\n• 连续频率范围：11.2 MHz至200 MHz\n-- 提供200 MHz至637.5 MHz的大多数频率\n\n• PLL1相位抖动\n（12 kHz至20 MHz）:\n460 fs rms（典型值）\n\n• PLL2相位抖动（12 kHz至20 MHz）\n- 整数N分频模式:470 fs rms（典型值）\n- 小数N分频模式:660 fs rms（典型值）;
