IFDDRCPE is a dual data rate (DDR) input D flip-flop with clock enable (CE) and asynchronous preset (PRE) and clear (CLR). It consists of one input buffer and two identical flip-flops (FDCPE). When the asynchronous PRE is High and CLR is Low, both the Q0 and Q1 outputs are set High. When CLR is High, both outputs are reset Low. Data on the D input is loaded into the flip-flop when PRE and CLR are Low and CE is High. The data is loaded into the Q0 output on the Low-to-High C0 clock transition. The data is loaded into the Q1 output on the Low-to-High C1 clock transition. The flip-flops are asynchronously cleared, output Low, when power is applied.
