are configured as inputs only. Control and configuration data is received over
ComPort 3. The SHB interface is clocked by the SMT338-VP system clock of 53MHz.
Configuration 2: Either SHB A or SHB B is configured to receive two 16-bit half-
words. The first 16-bits is used for data for channel A and the second 16-bits is used
for data for channel B. (This option is not implemented in firmware.)
The first configuration is ideal for higher speed data transfer. The second
configuration can be used if just one SHB is available on a module that the SMT381-
VP interfaces to. The two possible configurations are illustrated in the following

The connector used for the SHB interface is a 0.5mm Samtec QSH Type connector.
The full part number for this connector is: QSH-030-01-L-D-A-K
The pinout information for the two possible configurations for both SHB connectors is
given in the following table:
