DAC3482: BPSK

Ohad Bonneh
Intellectual 2660 points

Part Number: DAC3482

Tool/software:

IF I AM USING ONLY BPSK MODULATION (NEED ONLY ONE BIT) CAN I CONNECT ONLY THE MSB BIT AND LEAVE ALL THE OTHERS “NC” OR DO I HAVE TO CONNECT TO ALL 8/16 DIFF PAIRS DEPENDING ON BYTE/WORD MODE

    Ohad,

    This depends on the byte/word mode. In byte mode, you will have to connect all pairs. (MSB is shared with bit 7 in byte mode since it is a single line for both MSB and bit 7, see datasheet diagram for byte wide mode).

    In word mode, you can connect MSB to logic HI (with respect to LVDS threshold), and other pairs to logic LOW (with respect to LVDS threshold). Keep in mind that you would have to use offset binary mode in this fashion. TI also cannot ensure that the customer can achieve the performance needed with respect to the datasheet.
