PRODUCTION DATA.
After the transmitter detects the SYNC signal deassert, the transmitter waits until its next LMFC edge to start sending the initial lane alignment sequence. The ILAS consists of four multiframes each containing a predetermined sequence. The receiver searches for the start of the ILAS to determine the frame and multiframe boundaries. As the ILAS reaches the receiver for each lane, the lane starts to buffer its data until all receivers have received the ILAS and subsequently release the ILAS from all lanes at the same time in order to align the lanes. The second multiframe of the ILAS contains configuration parameters for the JESD204B that can be used by the receiver to verify that the transmitter and receiver configurations match.
