®
Application Specific Discretes
A.S.D.^TM
MAIN APPLICATIONS
In any electronic equipment where a suitable bus
termination is requiredto avoid signal reflectionsand
distortions :
PC and workstation computer
Data-line analyzers
RCD16-47B
RCD NETWORK
FOR BUS TERMINATION
DESCRIPTION
With the increasing speed of data transmission,
line reflections provide signal distorsions and the
overshoots or undershootsproduced on the signal
edges can cause the malfunction of the whole
system.
To avoid these negative effects from leading to
problems, a suitable termination is required.
Dedicated to bus termination, the RCD16-47B
provides by far the best method to minimise stray
emissions from PCB tracks.
