Figure 11-29. IDDRFXA Symbol
Table 11-7 lists the port names and descriptions for the IDDRFXA primitive.
Table 11-7. IDDRFXA Port Names
Figure 11-31 shows the LatticeXP2 Input Register Block configured in the IDDRXFXA mode. CLK1 used to register
the DDR registers and the first set of synchronization registers. CLK2 is used by the third stage of registers and
should be clocked by the FPGA clock. These clock transfer registers are shared with the output register block.
Figure 11-30. Input Register Block configured as IDDRFXA
Figure 11-31 shows the timing waveform when using the IDDRFXA module.
