Relation between CGEN, ADC, RxTSP, DAC and TxTSP clock frequencies

Hi @EnthuMan,

From this post:

Single tone generator test + sequence for other tests

Hi @EnthuMan, LimeSuite is actively maintained at the moment only. Other drivers may work as well, but you have to pay attention and know what you are doing. A and B channels are configured separately. Pay attention to MAC[1:0] register, which selects what channel is being configured. If you configure channel A only, then channel B is not configured. As I wrote, GFIRs are enabled after reset is applied. If you do not bypass them explicitly, then it cancels your IQ data. It generates four …

Tone frequency will be Ftxtsp / 8 (or 4) / DecimatioRatio. If TSGFCW[1:0] = 01b, TSGMODE = 0, INSEL = 1, HBD_OVR[2:0] = 000b (i.e. decimation by 2), then tone frequency generated by RxTSG will be 50/8/2 = 3.125MHz. Sample rate of this tone will be 25MHz, not 50 (decimation by 2, remember?).
