APPLICATIONS
ARCHITECTURAL OVERVIEW
The AMCC S5920 was developed to provide the
designer with a single multi-function device offering a
flexible and easy way to connect to the PCI bus. By
using the S5920, the designer eliminates the task of
assuring PCI bus specification compliance and the
necessity of understanding PCI bus timing require-
ments when interfacing a new application.
The complex 33 MHz PCI bus signals are converted
through the S5920 into an easy-to-use 8/16/32-bit
user bus referred to as the user Add-On bus. The Add-
On bus allows user add-on designs bus clock speed
independent operation to 40 MHz.
