AT7911E
8. Typical Applications
The AT7911E can be used for single board systems where standardised high speed interfaces
are needed. Even "non-intelligent" modules such as A/D-converter or sensor interfaces can be
assembled with the AT7911E because of the "control by link" feature. The complete control of
the AT7911E can be done via link from a central controller-node.
The AT7911E is a very high speed, scalable link-interface chip with fault tolerance features. The
initial exploitation is for use in multi-processor systems where the standardization or the high
speed of the links is an important issue and where reliability is a requirement. Further application
examples are heterogeneous systems or modules without any communication features as spe-
cial image compression chips, certain signal processors, application specific programmable
logic or mass memory.
