how to interface AD5542A dac ic with FPGA memory to provide input data to Din pin of AD5542A?

Around 256K data is stored as a bunch in memory and we need to convert this digital data to analog at once by applying it to AD5542A dac ic. As chip select need to go low to high after each 16 bit data to latch it to dac.
