22 Cross Connect (XC) Block Functional Description
There is another way to route DS2 signals for M12 MUX’s through LINETXDATA and LINETXCLK pins, if available,
by setting the block ID of XC_PDATA_Source_ID to 111 (refer to the Table on
ble of supporting DS2 demand clocking operation. In DS2 demand clocking mode, the LINETXCLK pins act as out-
puts; otherwise, they are input pins carrying incoming DS2 clocks. Depending on the clocking scheme, the channel
ID can be set up based on the following tables.
Table 619. XC_PDATA Source IDs for LINETXDATA Routing with Source Block = 111
Table 620. XC_PDATA Source IDs for LINETXCLK Routing with Source Block = 111
