Source Termination Method on Infometer Touch PCB Reverse Engineering The source termination method on Infometer Touch PCB Reverse Engineering, absorbs the reflected waveform with an impedance equal to that of the transmission line. This requires about 39 Ù in series with the internal output impedance of the driver, which is generally about 10 Ù. This…

High Speed DSP Interconnection on PCB Copy Below Figure shows a situation where several high speed DSPs must connect to a single point on PCB Copy, as would be the case when using read or write strobes bidirectionally connected from several DSPs. Small damping resistors shown in Figure A can minimize ringing provided the length…
