TX_DDR_G/B_A

The TX_DDR_G _A interfaces implement the DDR transmit interface where clock edges are aligned with the DDR data. The IOD block uses the fabric clock (TX_FAB_CLK) that is routed on a global clock resource to capture the transmitted data from fabric and transmit it via the TX pin.

The following figure shows the TX_DDR_G_A interface signal waveform.
