7.4.8 Lane Alignment Components
• Lane Alignment Master (LAM)
– Responsible for generating proprietary LS lane alignment initialization pattern
– Resides in the TLK10031 receive path
• Responsible for bringing up LS receive link for the data sent from the TLK10031 to a link partner
device
• Monitors the LS_OK_IN_A pins for “Link Status OK” signals sent from the Lane Alignment Slave
(LAS) of the link partner device
– Resides in the link partner device
• Responsible for bringing up LS transmit link for the data sent from the link partner device to the
TLK10031
• Monitors the “Link Status OK” signals sent from the LS_OK_OUT_A pins of the Lane Alignment
Slave (LAS) of the TLK10031
• Lane Alignment Slave (LAS)
– Responsible for monitoring the LS lane alignment initialization pattern
– Performs channel synchronization per lane (2 or 4 lanes) through byte rotation
– Performs lane alignment and realignment of bytes across lanes
– Resides in the TLK10031 transmit path
• Generates the “Link Status OK” signal for the LAM on the link partner device
– Resides in the link partner device
• Generates the “Link Status OK” signal for the LAM on the TLK10031 device.
Reference code from Texas Instruments is available for the LAM and LAS modules for easy integration
into FPGAs.
