The LTC6948 (and LTC6946) differential reference input is very similar to the LTC6951 reference differential. The only reason I mention this is we did a much better job in the LTC6951 datasheet showing preferred schematics for the differential case…
I believe your question is directed at the AD8342.
I support the LTC6948. I just wanted to make sure your customer was aware of the LTC6948's frequency gap between the output divider = 1 and output divider =2. Based on their LO frequencies…
We are planning to use your LTC6948 PLL for our application and as per your above statement, Either FracNWizard or ADIsimPLL both will support for Loop filter design of LTC6948 PLL.
But we have installed latest ADIsimPLL_V5_0_03 software and we are unable…
Thanks for your data.
Is it ADIsimPLL tool is updated with LTC6948 and released?
ADI offers a large number of frequency synthesizers:
The LTC6948-4 is a good candidate.
I'm assuming you're putting the 920MHz signal from the LTC6948 into the LO port of the LTC5562. Changes in the LO input power for an active mixer have minimal effects on the output. I would expect to see a small change at the output, but not much.…
The LTC6948's wide frequency range is made up of several smaller VCO's. There are plots on page 7 of the LTC6948 datasheet that show the approximate width of each VCO range. The LTC6948 will need to run a VCO calibration to select…
I noticed the datasheet Table 16 shows ALCEN defaults to 1.
However, the register map in table 15 suggests that ALCEN defaults to 0.
I assume that Table 16 is correct, and the ALCEN defaults to 1. So table 15 value for address h03 should be fixed to have…
