Загрузить техническое описание

The Keysight Technologies N4982 series of Clock Recovery Units provide a clean clock signal for BERT error detection, typically required when long delay time is in the channel. Each module has high input sensitivity, AC coupled data input terminated with a 50 ohm resistor to minimize reflections, low jitter output clock, and low power consumption.
