We have a design that has used TSB82AA2A and TSB41BA3B for years. We have recently switched to using TSB41BA3D PHY and now the interface does not work. There is apparently a problem in the process of creating bus topology and reading self-IDs. The document SLLZ060 "TSB41Ba3B to TSB41BA3D Transition Document" presents some modifications to the port speed/ mode selection but it is unclear how this might affect self-ID operation.
There is a document on the web that discusses an issue with these two chips not recognizing the local self-ID and presents a method of reading PHY registers to create a self-ID because the chip combination does not work. See me.in-berlin.de/.../1327-firewire-ohci-tsb41ba3d-support-tweaks.patch
We have used TSB41BA3D with TSB12LV01BPZT with good results.
Has anyone else experienced this problem? Is there another errata document? Is there a solution to this issue?
