AD9980 offset voltage level

Hi Guys,


You know AD9980 is already out of market, and it has been replaced by a new one, but I happen to have a Xilinx ML506 FPGA board integrated an AD9980. I got a question regarding the voltage level with the offset value.


The registers [0x0B, 0x0C], [0x0D, 0x0E], [0x0F, 0x10] are for offsets of the three R/G/B channels, and each one goes from 0 to 255. Could you tell me what is the actual voltage level at 0 and what is the voltage at 255? The registers for three gains do have the voltages of 0.5V and 1.0V with register values 0 and 127 respectively. Many thanks in advance.
