Hello Rob,
I think that I have found the issue: It is probably the switching frequency of a power regulator, a simple switcher LMZ12003, which is placed to close to some coils of an IF-Filter in front of the ADC input. If I hold a ferrite bead for a cable…
Part Number: ADC3444
Dear Forum members.
We are having some trouble with unwanted noise on the input of the ADC.
With absolutely no input signal connected to the input of the ADC only the passive input filter.
we are measuring noise with the oscilloscope…
Part Number: ADC3444
I am working with ADC3444 connecting to fpga. I am confused by the SPI configuration, showing followed.
I use a standard SPI from processor(zynq PS), the question is how we should prepare the sequence, MSB first or LSB first. For…
Part Number: ADC3444 Other Parts Discussed in Thread: THS4541 , , ADC3643EVM , I am working on an application where I must use an ADC344x series device hooked to a device with an output impedance of 6.6 K ohm in parallel with 3.6 pF. I understand that the…
Part Number: ADC3444 Hello,
We want to interface the ADC3444 with a FPGA Ultrascale+ from Xilinx. The ADC work in 2 wires mode with a frame clock which encapsulates 2 samples.
We saw the application note from Xilinx which describes a deserialization 1…
Part Number: ADC3444 We could able to configure the ADC3444 and we are able to get the samples, to check the spectral components in the samples is there any software? whether the software can able to analyze the samples and give the SFDR ?Thanks in advance…
Part Number: ADC3444 Other Parts Discussed in Thread: ADC3443 Hello,
My team has chosen ADC3444 for IF sampling application for a 25kHz BW signal. We will use it for 1-wire LVDS configuration, i.e. 80MSPS max. I would like to know if this Quad-Channel…
Part Number: ADC3444 Hi is there any supporting VHDL code for receiving the data from ADC3444, as already EVMs are present for the device, If so where can i find the VHDL code?
