National DS40MB200 handbook

The DS40MB200 is a dual signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy applications. Signal conditioning features include input equalization and programmable output pre-emphasis that enable data communication in FR4 backplanes up to 4 Gb/s. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have 4 selectable steps of pre-emphasis to compensate for transmission losses from long FR4 backplanes and reduce deterministic jitter. The pre-emphasis levels can be independently controlled for the line-side and switch-side drivers. The internal loopback paths from switch-side input to switch-side output enable at-speed system testing. All receiver inputs and driver outputs are internally terminated with 100Ω differential terminating resistors.

National LM75 handbook

This document describes the analysis of pesticide 1,2,3,4,5,6-C6H6Cl6 concentration in seafood samples using Agilent EnviroPrep and gel permeation chromatography (GPC). The EnviroPrep column, filled with a high-resolution macroporous packing material, was selected for separation. The column is made of stainless steel and can be used in any high-pressure liquid chromatography system. The macroporous packing material has a strong and permanent pore structure, providing excellent separation efficiency in non-sample loading-intensive analysis. The small pore size eliminates interference from high molecular weight compounds and maximizes separation efficiency.
