Microchip晶振耐辐射低功耗低抖动六输出时钟发生器
传统宇航设备多通道时钟系统,需要依托多颗独立振荡器,时钟缓冲器,分频器组合搭建,不仅占用大量PCB布局空间,增加整机结构重量与装配复杂度,还会因不同器件的参数差异,温度漂移,抗干扰能力参差不齐,造成多通道时钟信号不同步,相位偏移,一致性差等问题,大幅提升系统故障率与研发成本.MicrochipDSA504RT是专为空间级场景量身打造的可编程六输出时钟发生器,颠覆传统分立设计方案,单颗芯片即可实现六路独立时钟信号输出,支持差分与单端多种输出模式,输出频率最高可达875MHz,可精准匹配卫星导航,高速通信,姿态测控,数据采集,星上处理器等多模块差异化时钟需求.
该器件支持通过单一主时钟源生成六路相位对齐,频率精准,同步性极强的时钟信号,彻底替代多颗分立晶振与时钟芯片,大幅精简系统元器件数量,降低PCB布局难度,缩减整机体积与重量,有效提升系统FIT可靠性指标,减少设备故障隐患.同时芯片支持可编程频率配置,无毛刺频率切换,静态相位偏移调节,可灵活适配不同航天设备的时序定制需求,兼顾通用性与适配性,完美适配微小卫星,深空探测器,航天运载设备,军工测控终端等轻量化,集成化设备的设计要求.
