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 — 具有高速比较器的 LVDS 数据和时钟恢复电路

LVDS 信号恢复电路在数字系统中用来检索失真时钟或数据波形。由于存在杂散电容、杂散电感或传输线反射,这些时钟和数据信号在长迹线上会衰减和失真。该比较器用于检测衰减和失真的输入信号,并将其转换为满量程 LVDS 输出信号。此电路还可用于从单端信号转换为 LVDS 信号。在这种情况下,动态基准电压将连接到比较器的反相终端,该端从输入信号中提取共模电压。
