ing character, and remembers its location in the buffer. At
some point, one transceiver designated as the master
instructs all the transceivers to align to the channel bonding
character "P" (or to some location relative to the channel
bonding character).
After this operation, words transmitted to the FPGA fabric
are properly aligned: RRRR, SSSS, TTTT, and so forth, as
shown in the bottom-right portion of
the channels remain properly aligned following the channel
bonding operation, the master transceiver must also control
the clock correction operations described in the previous
section for all channel-bonded transceivers.
Transmitter Buffer
The transmitter's buffer write pointer (TXUSRCLK) is fre-
quency-locked to its read pointer (REFCLK). Therefore,
clock correction and channel bonding are not required. The
purpose of the transmitter's buffer is to accommodate a
phase difference between TXUSRCLK and REFCLK. A
simple FIFO suffices for this purpose. A FIFO depth of four
will permit reliable operation with simple detection of over-
flow or underflow, which could occur if the clocks are not fre-
quency-locked.
