We use AD9957 in single dac mode. in the spec , it wrote that it could receive 250Mhz IQ data rate. Does this means that we can set PDCLK at 250Mhz, and the input IQ parallel lines data rate is 250Mhz ?
And if this was true , it was hard to use parallel port at so high frequency ?
If we want to use the high input IQ frequency about 150Mhz, is there any device about circuit and pcb design ?
Thanks all !
