Description
interface_clock
1
core_clock
Output
Clock for data transfer across the sink core
interface in the advanced clocking mode.
interface_
clock_reset
1
core_clock
Output
The core asserts this signal when the
core_
reset
signal is high and deasserts this signal
when the reset sequence is complete in the
advanced clocking mode.
link_up
1
Standard
clocking: user_
clock
Advanced
clocking: core_
clock
Output
The core asserts this signal to indicate that
the core initialization is complete and is
ready to transmit user data.
data
64xN Standard
clocking: user_
clock
Advanced
clocking: core_
clock
Output
This vector carries the transmitted streaming
data from the core.
N represents the number of lanes.
sync
8
Standard
clocking: user_
clock
Advanced
clocking: core_
clock
Output
The sync vector is an 8 bit bus. The data
value at the start of a burst and at the end of a
burst are captured and transported across the
link.
Note: This vector is not associated with
Interlaken channelization or flow
control schemes.
valid
1
Standard
clocking: user_
clock
Advanced
clocking: core_
clock
Output
This single bit signal indicates that the data is
valid.
start_of_burst
1
Standard
clocking: user_
clock
Advanced
clocking: core_
clock
Output
When the core is in burst mode operation,
assertion of this signal indicates that the
information on the data vector is the
beginning of a burst.
Because continuous mode is one long burst,
in this mode the signal is asserted only once
at the start of the data.
