*CY7C2663KV18 - 450BZI has an internal PLL and that PLL is controlled via DOFF pin (pll turn off (active low)).
* When this part selected in the Xilinx MIG IP, it generates a qdriip_dll_off_n pin.
* In the MIG IP datasheet it is written that qdriip_dll_off_n pin turns off the internal DLL in the memory device. What is the DLL ? This DLL is PLL in the part CY7C2663KV18 - 450BZI ? This part CY7C2663KV18 - 450BZI does not contain any internal DLL, does it ? If there is no internal DLL in the part CY7C2663KV18 - 450BZI, why Xilinx MIG IP generates this qdriip_dll_off_n pin ? Or DLL and PLL is different things ? Should I connect these two pin to each - other, or not ?
