ad9778 is an high speed 14 bit dac,

Ireference of the dac is 12ma when i use 100 ohms at i120 pin of it, so in oreder to find a full scale current of the dac i need dac gain , gain of the dac is 10 bit that can be set by reg 0A,0C, for i phase dac , what is the range of gain in this ic?


synco(p/n) i made nc, but synci(p/n) is needed in order to latch the datainput, so i have connected a fpga bank which is operating at 2.5v, where as synco is at 3.3v level so how to interface it ? is it through level translator?
