Re: FM-Comms2/ZC706 GUI question
Micheal Thanks for the reply. I have another question. On the Tx GUI, there is a DAC Buffer Output file that can be loaded from the GUI called "qpskwithfilt_30.72MHz.txt. I assume the sampling clk...

Re: ADAU1361, PLL and Fs=32kHz
Alexander, It's a little bit confusing, but just set up the PLL to output 1024 * 48 kHz = 49.152 MHz. X = 2, N = 721, M = 1125, R = 3. Then use the converter control registers to select 32 kHz instead...

Hi, and I guess driving the differential ADC input in a single-ended way would decrease the performance of the ADC severly? My problem at this point is not just the noise the OpAmp would add to the...

UweBonnes, With really high speed op amps, a large feedback resistor with the op amp input capacitance will give you a pole. Change the 1k/10k resistors to 220/2.2k and see if the frequency of...

Hi Jim, Right-- I was assuming you weren't randomly changing but it's good you checked that it was set properly anyway after the swap since that question would have come up eventually. Dave
