產品敘述
SKY63104/05/06 是一系列超高效能的抖動衰減器,內建第五代 DSPLL® 與 MultiSynth™ 技術,搭配超低抖動 VCO,可在 112G/224G PAM4 SerDes 及相干光通訊等高階應用中,實現任意頻率的時鐘產生與抖動抑制。此裝置提供 12 路輸出,超低抖動僅 55 fs,輸出頻率可達 3.2 GHz,且誤差為 0 ppm。迴路濾波器全數內建於晶片上,免除分立元件雜訊耦合的風險。此外,其抖動衰減頻寬可透過數位方式程式化設定,讓您在應用層級最佳化抖動效能。- SKY63104:1 組 DSPLL + 2 組 MultiSynth
- SKY63105:2 組 DSPLL + 1 組 MultiSynth
- SKY63106:3 組 DSPLL
所有器件支援自由振盪(Free-Run)、同步(Synchronous)及保持(Holdover)模式,並具備強化的無縫切換(Hitless Switching)功能,將輸入時鐘切換時的相位瞬變降至最低。可選配內建非揮發性記憶體(NVM),以預設開機頻率設定,或搭配外部快閃記憶體方案。使用 Skyworks ClockBuilder® Pro(CBPro)軟體即可快速完成 SKY63104/05/06 的程式化設定;裝置可由工廠預先燒錄,也可空白出貨,以提供更大彈性。
