产品叙述
SKY63104/05/06 抖动衰减器结合第五代 DSPLL® 与 MultiSynth™ 技术，搭配超低抖动 VCO，可在 112G/224G PAM4 SerDes 和相干光通讯等高性能应用中提供小于 55 飞秒（fs）的超低相位抖动。它们专为对集成度和抖动性能要求最高的场景而设计；所有 PLL 组件均已内置芯片，消除了分立方案可能带来的噪声耦合风险。- SKY63104：1 个 DSPLL + 2 个 MultiSynth
- SKY63105：2 个 DSPLL + 1 个 MultiSynth
- SKY63106：3 个 DSPLL
所有器件支持自由运行（Free-Run）、同步（Synchronous）及保持（Holdover）模式，并具备增强型无缝切换（Hitless Switching）功能，将输入时钟切换时的相位瞬变降至最低。可选配内置非易失性存储器（NVM），以实现开机即带预设频率配置，或使用外部闪存方案。通过 Skyworks ClockBuilder® Pro (CBPro) 软件，即可轻松完成对 SKY63104/05/06 的编程——可由工厂预编程，开机即生效；也可空白出货，提供更大灵活性。
