RCD16-47B

® RCD16-47B RCD NETWORK FOR BUS TERMINATION 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 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. FEATURES NETWORK OF 16R-C-D LINETERMINATIONS RESISTANCE : R = 47 Ω, TOLERANCE +/- 10% CAPACITANCE: C = 33 pF, TOLERANCE +/- 10% SCHOTTKY DIODE : (D) BENEFITS Provides impedance matching, thus increasing noise immunity and minimizing distortion. Lowers EMI / RFI radiation. No DC power dissipation. Eliminates negative voltages : no current will change the bias of the protected device. Uses the best of all termination schemes.
