What and Why's of termination?
I am new to electronics, and don't understand what is termination and why it is needed, especially in digital communications.
Thanks

When do you need a complex termination?
The formula for the characteristic impedance is below
So the characteristic impedance is a complex number. But why is a complex termination generally not used?
With complex termination I mean a transmission line terminated by more than just a…

HCMOS drivers impedance table
I wonder, is there a table somewhere where I can find out impedance of drivers of various HCMOS series?
I am specifically interested in AC, ACT, LVC and HC series. I guess input impedance is very high for all CMOS-based series, so I am interested in…

How to determine the value of termination resistor?
How to determine the value of the termination resistor? Is the termination resistor used to reduce the reflection of the signals and also have to match with the transmission impedance? How am I going to determine the transmission impedance in order…

I2S - Ribbon Cable - Termination
I have 2 boards connected via a ribbon cable.
CPU board is an 3.3v ARM providing the I2S signals(bit clk, data, L/R signal). I'm using 44100 - 16 bit audio so the bit clock is just approx 1.4 mhz.
The second board has a TI PCM5100 DAC. (I made a…

How to make a SCSI-3 terminator?
I have an old VAXstation that has an external SCSI Bus.
When I don't have anything attached to that, I get errors. I was thinking of adding a terminator, but those that I found online are quite expensive. So I was thinking of wiring one myself.
Does…

Series termination on an input pin?
On a development board, I found this schematic for an up to 100 MHz clock input/output pin hooked up to a 2.54 mm pin header block:
The 22 ohm series termination makes sense if the pin is configured as an output, but how should this be driven as an…

Series Termination value is very large
I am budding engineer working on RE testing. I know about series termination. We are using 50 ohm as trace impedance. We are getting large reflection and emission in SD clock. I used series resistor values upto 33 ohm as suggested in datasheet. But…

In which pratical cases are used parallel and thevenin terminations?
I've found some theory about various type of terminations but I can't figure in which cases are used parallel(pullup with half driving voltage and pulldowns) and thevenin termination. Since I'm used to simply boards with microcontrollers, where I…
