Detailed Description
14. IIC Bus
The SP605 implements three IIC bus interfaces at the FPGA.
The MAIN IIC bus hosts four items:
•
FPGA U1 Bank 1 "MAIN" IIC interface
•
8-Kb NV Memory U4
•
FMC LPC connector J2
•
2-Pin External Access Header J45
The DVI IIC bus hosts two items:
•
FPGA U1 Bank 2 DVI IIC interface
•
DVI Codec U31 and DVI connector P3
The SFP IIC bus hosts two items:
•
FPGA U1 Bank 0 SFP IIC interface
•
SFP module connector P2
The SP605 IIC bus topology is shown in
