INTERFACE_TYPE Attribute
Table 8-3: Allowable Data Widths
When the DATA_WIDTH is set to widths larger than six, a pair of ISERDES must be
configured into a master-slave configuration. See
expansion is not allowed in memory mode.
The INTERFACE_TYPE attribute determines whether the ISERDES is configured in
memory or networking mode. The allowed values for this attribute are MEMORY or
NETWORKING. The default mode is MEMORY. It is recommended to use the Memory
Interface Generator (MIG) when using ISERDES in Memory mode.
When INTERFACE_TYPE is set to NETWORKING, the Bitslip submodule is available and
the OCLK port is unused. Even if the Bitslip module is not used in networking mode,
BITSLIP_ENABLE must be set to TRUE, and the Bitslip port can be tied Low to disable
Bitslip operation. When set to MEMORY, the Bitslip submodule is not available
(BITSLIP_ENABLE must be set to FALSE), and the OCLK port can be used.
