Part Number: LMX2594 Tool/software: Hi,
I have a few questions regarding the differential output:
Can I use a differential output directly without converting it to single-ended. Purpose : To provide a sampling clock for a DAC. Sampling Frequency : 12 G…

Part Number: LMX2594 Tool/software: Hi,
Since my customer is planning to use an external active loop filter, what voltages are expected or allowed to be applied to the VTune pin of the device? 0 to 3.3V for all VCO bands?
Best regards
Hi Anand,
If your configuration is like below, the 50MHz spurs is likely a fractional spurs.
You can reduce fpd to 100MHz, the 50MHz spurs should go away.
I have other suggestions for you.
- change channel B to VCO output
- reduce charge pump current…

Anand,
Spurs are a harsh reality of any PLL, but what you are showing looks higher than what I would typically expect. One thing from the schematic is it seems that you are using a crystal. Be aware that if the input frequency is low, then the slew rate…
Part Number: LMX2594 Tool/software: Hi team,
Do the frequency dividing ratio of Pre_R and R registers affect SYNC function and how they affect? We can find the relevant explanation in LMX2594 datasheet? Thanks.
