Tool/software:
Hi,
I am using this component for a PCB design. I want to match impedances to reduce ringing.
I am looking at the IBIS model and comparing it to the datasheet. I am unable to infer the setup for parameter extraction. Can you please help to elucidate how the source impedance could be extracted?
The test fixture in the datasheet and my expectation do not match.
- Why does the datasheet callout 2*Vcc
- Why is there a V_fixture = 1.8V for the rising waveform?
- Why are there load resistors?
I am also trying to calculate the source impedance for the following devices using the IBIS dataset:
SN74AUC04RGYR
LMK1C1102PWR
SN74AXC1T45DRLR
74AUC1G74
SN74AUC08RGYR
SN74ALVC04DGVR
LMK03318RHSR
