The OQ port is the data output port of the OSERDES module. Data at the input port D1
appears first at OQ. This port connects the output of the data parallel-to-serial converter to
the data input of the IOB.
This port is the 3-state control output of the OSERDES module. When used, this port
connects the output of the 3-state parallel-to-serial converter to the control/3-state input of
the IOB.
This high-speed clock input drives the serial side of the parallel-to-serial converters.
This divided high-speed clock input drives the parallel side of the parallel-to-serial
converters. This clock is the divided version of the clock connected to the CLK port.
All incoming parallel data enters the OSERDES module through ports D1 to D6. These
ports are connected to the FPGA fabric, and can be configured from two to six bits (i.e., a
6:1 serialization). Bit widths greater than six (up to 10) can be supported by using a second
OSERDES in SLAVE mode (see
page 369
corresponding bit order of the ISERDES.
OCE is an active High clock enable for the data path.
All parallel 3-state signals enter the OSERDES module through ports T1 to T4. The ports
are connected to the FPGA fabric, and can be configured as one, two, or four bits.
