This is with reference to the terminology in the Programming guide and the connection to the waveforms in the datasheet.
There is the use of the word “Frame” which I am unable to trace.
Reg 0x0023, LMLx_FIDM: frame start ID selection. What does this mean?
Reg 0x0024, Sample source in positions 0,1,2,3. Where are these positions defined?
Is the TRXIQPULSE mode same as JESD 207 mode?
From the FPGA code I understood that there are four modes of operation of the limelight interface:
Please advise on how are these configured.
3.1) Register 0x0022, LMLx_SISODDR (DDR mode off/on). Does turning it OFF enable SISO_SDR mode ON?
3.2) How is MIMO_DDR mode enabled (does turning OFF TRXIQPULSE mode off enable MIMO_DDR)?
3.3) Could you please provide the waveform for SISO_DDR mode? My understanding is the following:
Figs 33-36: are PULSE_DDR/JESD 207 mode
Figs 37-38: are MIMO-DDR mode which is same as TRXIQ DDR mode
Figs 39-40: are SISO-SDR mode
Thanks as always for your time and help,
