We are having a difficult time with our latest revision of the
PacketRunner2i. This is the board with the Intel processor
and PCH part. The new board has a short on the 1.05V ASW
power supply. When the PCH part is removed, the short clears.
Both boards have the same pads connected to the 1.05V ASW
power supply and the ground pads are the same in both designs
We are having problems with a short to ground on the 1.05V ASW
power line. Our previous run of boards had exactly the same
pins connected to 1.05V ASW and ground and we did not get the
1.05V ASW line shorted to ground.
The 82C226 parts were purchased at different times. I have
chosen a sample of parts from different purchases. All the 82C226
parts have four different markings on them, none of them being
the device part number. Can you tell us if the following parts
are all identical 82C226 devices? Have there been any changes
in power pins assignments recently in this part?
