描述：SI53344-B-GM
低抖動 LVDS 扇出時鐘緩沖器，具有多達 10 個來自任意格式輸入的 LVDS 輸出和來自直流的寬頻率范圍高達 1250 MHzSI53344-B-GM系列 LVDS 扇出緩沖器是時鐘/數據分配和冗余時鐘應用。這些器件具有 50 fs 的典型超低抖動并在從直流到 1250 MHz 的寬頻率范圍內運行。內置 LDO 提供高 PSRR 性能并減少對外部組件的需求噪聲環境中的抖動時鐘分布。它們有多種配置，并提供可選的輸入時鐘，使用2:1 輸入多路復用器。其他功能包括獨立輸出啟用和內置格式翻譯。這些緩沖器可以與SI53344-B-GM時鐘和 Si5xx 振蕩器配對以提供端到端的時鐘樹性能。
• 超低附加抖動：50 fs rms
• 具有高 PSRR 性能的內置 LDO
• 多達 10 個 LVDS 輸出
• 任何格式輸入（LVPECL、低功耗
LVPECL、LVDS、CML、HCSL、LVCMOS)
• 寬頻率范圍：直流至 1250 MHz
• 輸出啟用選項
• 多種配置選項
• 2:1 輸入多路復用器
• 符合 RoHS，無鉛
• 溫度范圍：–40 至 +85 °C
功能說明：SI53344-B-GM
Si53340-45 是一系列低抖動、低偏斜、固定格式 (LVDS) 緩沖器。 Si53340/42/SI53344-B-GM有一個通用輸入，可以接受
最常見的差分或 LVCMOS 輸入信號，而 Si53341/43/45 僅接受 LVCMOS 輸入。這些設備可用
在為最終應用定制的多種配置中（有關配置的更多詳細信息，請參閱 1. 訂購指南）。2.1 通用、任意格式輸入端接 (Si53340/42/44)通用輸入級可實現與各種時鐘格式的簡單接口，包括 LVPECL、低功耗 LVPECL、LVDS、
CML、HCSL 和 LVCMOS。下表總結了器件支持的各種交流和直流耦合選項。為了
最好的高速性能，建議使用差分格式。對于單端和差分輸入時鐘，
建議使用盡可能快的壓擺率，因為低壓擺率會增加本底噪聲并降低抖動性能。盡管
不需要，建議差分格式的最小壓擺率為 0.75 V/ns，單端格式建議為 1.0 V/ns。看
