DAC39RF10: CAN I use JMODE=2 for 1 real data stream?

Part Number: DAC39RF10

Tool/software:

To the TI Support Team,

CAN I use JMODE=2 for 1 real data stream without interpolation, LT=1?

The number of lanes to use is 4.

With the above configuration, I can not select JMODE of 2 in the DAC39RF1xEVM GUI.

the update Rate is 1.0GHz, DAC resolution is 16 bit, JSED protocol is 8b10b and subclass is 1.

Best regards,
Jeongju Go

  • Jeongju, 

    Yes JMODE2 is a valid JMODE for 1x interpolation (real data) at a sample rate of 1GSPS. The GUI has a bug where it does not find JMODE2 with a single stream but the device does support this. (LMFS 4-1-2-4 5Gbps)
