Repeat the following sequence of 12 characters four times:

/D30.5/ (CTL=0, Data=0xBE)

/D23.6/ (CTL=0, Data=0xD7)

/D3.1/ (CTL=0, Data=0x23)

/D7.2/ (CTL=0, Data=0x47)

/D11.3/ (CTL=0, Data=0x6B)

/D15.4/ (CTL=0, Data=0x8F)

/D19.5/ (CTL=0, Data=0xB3)

/D20.0/ (CTL=0, Data=0x14)

/D30.2/ (CTL=0, Data=0x5E)

/D27.7/ (CTL=0, Data=0xFB)

/D21.1/ (CTL=0, Data=0x35)

/D25.2/ (CTL=0, Data=0x59)

The above 49-character sequence is repeated until LS_OK_IN is asserted. Once LS_OK_IN is asserted,

the LAM resumes transmitting traffic received from the high speed side SERDES immediately.

The TLK10232 performs lane alignment across the lanes similar in fashion to the IEEE 802.3-2008 (XAUI)

specification. XAUI only operates across 4 lanes while LAS operates with 2 or 4 lanes. The lane alignment

state machine is shown in Figure 5-3. The TLK10232 uses the comma (K28.5) character for lane to lane

alignment by default, but can be provisioned to use XAUI's /A/ character as well.

Lane alignment checking is not performed by the LAS after lane alignment is achieved. After LAM detects

that the LS_OK_IN signal is asserted, normal system traffic is carried instead of the proprietary lane

alignment pattern.

Channel synchronization is performed during lane alignment and normal system operation.
