I have designed a FPGA based DDS that creates digital signals between 0-70MHz. Now I want to convert my digital data into analog. As the base frequency is 200MHz, I need a high performance parallel DAC with minimum 200MSPS. As I widely searched, such DACs are plentiful but I couldn't find one without a latch. All I found work like this: data is sent to D0-Dx -> a clock latches the data -> conversion is done.
If I want to have a DAC with this system, my output frequency will be reduced to 1/2 ( one clock for D0-Dx + one clock for the data latch).
Anyone knows a part with such properties ( something that works like DAC80xx , but in high frequencies, something like this:) ?
