Xilinx Kria K26 SOM User Manual

Table 1: SOM240 Signal Naming Conventions
Signal Description
Module (M) The SOM, in this case the K26 SOM
Carrier card (C) The board that the SOM is plugged into is called the carrier card
C2M Signal names with C2M indicate that the signal is driven by the carrier card and received by
the SOM
M2C Signal names with M2C indicate that the signal is driven by the SOM and received by the
carrier card
_P The postfix _P on differential signal pairs indicates the positive component of a differential
signal
_N The postfix _N on differential signal pairs indicates the negative component of a differential
signal
_L The postfix _L on a single-ended signal indicates an active-Low signal. This is used for the
connector pinouts only. The postfix _B is also used to indicate an active-Low signal.

SOM240_1 Connector Pinout
The SOM240_1 connector provides access to two MIO banks (MIO501, MIO502), HPIO bank 66
(HPA), HDIO bank 45 (HDA), and the PS-GTR transceivers (MIO505). It also provides sideband
signals for conguraon and operaon of the board.
