9FG830
Eight Output Differential Frequency Generator for PCIe Gen3 and QPI
12
General SMBus serial interface information for the 9FG830
How to Write:
Controller (host) sends a start bit.
Controller (host) sends the write address DC
(H)
IDT clock will acknowledge
Controller (host) sends the begining byte location = N
IDT clock will acknowledge
Controller (host) sends the data byte count = X
IDT clock will acknowledge
Controller (host) starts sending Byte N through
Byte N + X -1
(see Note 2)
IDT clock will acknowledge each byte one at a time
Controller (host) sends a Stop bit
How to Read:
Controller (host) will send start bit.
Controller (host) sends the write address DC
(H)
IDT clock will acknowledge
Controller (host) sends the begining byte
location = N
IDT clock will acknowledge
Controller (host) will send a separate start bit.
Controller (host) sends the read address DD
(H)
IDT clock will acknowledge
IDT clock will send the data byte count = X
IDT clock sends Byte N + X -1
IDT clock sends Byte 0 through byte X (if X
(H)
was written to byte 8).
Controller (host) will need to acknowledge each byte
Controllor (host) will send a not acknowledge bit
Controller (host) will send a stop bit
