产品叙述
SKY62101 时钟发生器结合第五代 DSPLL® 与 MultiSynth™ 技术及超低抖动 VCO，可在 PCIe Gen 1/2/3/4/5/6/7 相容的高性能应用中提供小于 55 fs 的超低相位抖动。该器件广泛应用于 112G/224G SerDes、相干光通讯和数据中心设备等对集成度与抖动性能要求极高的场景。所有 PLL 组件均已集成于芯片之上，消除了分立方案带来的噪声耦合风险。SKY62101 支持锁定外部晶振或振荡器的自由运行与同步模式。可通过 Skyworks ClockBuilder® Pro (CBPro) 软件快速完成配置，CBPro 会为每个配置生成专属料号。选用定制料号出厂时即预先编程，开机即可使用；也可选择空白出货，用户可在上电时或通过 CBPro Field Programmer 通过串行接口将配置写入非易失性存储器 (NVM)，以实现现场灵活编程。
