The LMH7220 is a high speed, low power comparator with an operating supply voltage range of 2.7V to 12V. The LMH7220 has a differential, LVDS output, driving 325 mV into a 100Ω symmetrical transmission line. The LMH7220 has a 2.9 ns propagation delay and 0.6 ns rise and fall times while the supply current is only 6.8 mA at 5V (load current excluded).

The LMH7220 inputs have a voltage range that extends 200 mV below ground, allowing ground sensing applications. The LMH7220 is available in the 6-Pin SOT package. This package is ideal where space is a critical item.

CIRCUIT060087 — 具有高速比較器的 LVDS 資料及時鐘恢復電路

LVDS 訊號復原電路用於數位系統,以擷取扭曲的時脈或資料波形。由於雜散電容、雜散電感或傳輸線路上的反射,這些時脈與數據訊號會在長走線上衰減和失真。比較器用於感測衰減和失真的輸入訊號,並轉換為全刻度數位 LVDS 輸出訊號。此電路也可用於將單端訊號轉換成 LVDS 訊號。在該情況下,動態參考電壓會連接至比較器的反相端子,以從輸入訊號中擷取共模電壓。
