AD603 Data Sheet Circuit - Figure 49, page 18
Hello: I am making an amateur radio transceiver. I have based the IF strip of the receiver section of the transceiver on the circuit shown in the data sheet page 18 (figure 49). My circuit is as...

Re: Sigma300 (ADAU145x) Q&A
Hello, The Limiter block behaves similarly for me:Its "Flag" output is actually the Ratio output (thus is all over the place)Presumably, then, the "Ratio" output is the Flag -- but it's dead....

Thanks for a great answer, i think i was confused about the timing diagram on figure 2 on page 7 before, but i makes more sense now. One last question. The 2 output bits on each differential pair, do...

Bob, You are the best. Your test is much appreciated.It's really strange though. Which SigmaStudio version are you using?I'm running 3.11 Build 2, Rev 1396 (9/8/2014) and the limiter does not limit at...

Hi Dave, There is a 8-bit gray-level raw image of 128 pixels X 128 pixels stored in a SRAM. All the pixels are active pixels. MCLK=20MHz,VCLK=20MHz. I use custom sepcific mode to put the image on VDATA...

Re: Sigma300 (ADAU145x) Q&A
Hello, I'm using the same version (3.11, build 2, rev 1386, 9/8/04). The discrepancy between the limiter's -10 dB threshold and the observed 0.5 (-6 dB) reading puzzled me as well. As it...
View ArticleADF4355-2 output range
Looking at the ADF4355-2 data sheet, it seems that the VCO tuning range covers 3400-6800 MHz, but the part's output frequency range only extends to 4400 MHz. Can you clarify what limits the usable...

Re: Decreasing ADF5355 Lock Time
I have a similar question. Figure 28 and its caption are not conveying the same information. In the caption it says "Lock Time for 100 MHz Jump from 3500 MHz to 7000 MHz", but in the figure we see the...

I'm not a expert in Arduino and haven't looked into the details of your code, but if you use the SPI lib, can it be that the SPI transfers split 24-bit transfers into 3 x 8-bit transfers? That isn't...

Helle Wayne, I think the slope in Fig. 37 fits well to a second order filter: take e.g. the orange curve (+/-5V): at 40kHz I read -15dB, at 80kHz I read -25dB, which is better than 6dB per octave. I...
