Part Number: LMX2824EPEVM Tool/software: The datasheet I have is preliminary, so I think it’s missing some info.
Table 7-2 indicates how to determine the PFD_DLY_SEL value based on MASH_ORDER and VCO frequency, but PFD_DLY_SEL doesn’t show up in the…
Part Number: LMX2824EPEVM Tool/software: Hello,
Is rb_LD_VTUNE really in R110[10:9] per the datasheet or is this a carryover from another PLL IC?
Either way, can you provide the register location and definition for rb_LD_VTUNE?
Thanks, John
Part Number: LMX2824EPEVM Tool/software: R3[15:14] is the 2 bits that select the RFOUTB configuration.
I believe the doubler output is available at RFOUTB, but don't see it as an option in Table 8-6 (below).
Is the doubler output available at…
Part Number: LMX2824EPEVM Tool/software: Hello (Noel),
Should resistive or inductive pull-ups be used on the LMX2824 RF outputs?
The datasheet indicates there are internal pull-ups, but the next sections discuss adding either a resistor or inductor…
Part Number: LMX2824EPEVM Other Parts Discussed in Thread: LMX2595 Tool/software: The 'full assist' mode of tuning the LMX2824 skips calibration and requires programming a number of different values: VCO_SEL, VCO_CAPCODE, VCODACISET, DBLR1_PD, DBLR_AMP_CAPCTRL…
Part Number: LMX2824EPEVM Other Parts Discussed in Thread: LMX2595 Tool/software: Hi Noel,
I have the full assist working in my setup.
I created routine to tune across the band and record VCO_SEL, VCO_DACISET, and VCO_CAPCTRL. I initialize with R4…
