Interlaken Interface

The Interlaken interface consists of 24 full-duplex transceiver channels with
AC-coupling on the receiver data. The header connector transmits data across the
interface while the receptacle connector receives data from the interface.

Since the pin labeling of the header and receptacle connectors are mirror image of
each other, the transmit and receive differential pairs have the same pin assignment.
For example, TX_P0 at A7 of header mates with RX_P0 at A7 of receptacle.

Table 2–33

lists the pin assignments for the Interlaken interface and their

corresponding schematic signal names and Stratix V GX pin numbers.
