The TI E2E™ design support forums will undergo maintenance from July 11 to July 13. If you need design support during this time, open a new support request with our customer support center.
Part Number: ADC3644 Tool/software: Hello, I am essentially attempting to design a ~1 MHz Bandwidth SDR (with I and Q outputs) and have not been able to develop a scheme to acquire the 16-bits x 2 (IQ) x 2 (Nyquist) x 1MHz = 64MHz of serial data. Currently…
Part Number: ADC3644 Tool/software: I am using the ADC3644 in my design, paired with a low-pass filter and glitch filter as per the datasheet recommendations. However, I am observing beat frequencies in the ADC output that seem to correspond to the ADC…
Part Number: ADC3644 Hi team,
I use the ADC3644 with an external 1.6V reference. I attach the waveforms of each power supply and VREF. It will take some time for VREF to stabilize, but is there any problem as long as each power supply and VREF are stabilized…
Part Number: ADC3644 Other Parts Discussed in Thread: OPA837 , , REF3318 Hi team,
In the EVM of ADC3644, 1.6V of VREF is divided and supplied by REF3318 and OPA837. Is this because there was no 1.6V reference? If I use the ADC3644 with an external reference…
Part Number: ADC3644 Other Parts Discussed in Thread: ADC3664 , Dear Technical Support Team,
Do you have Comparison chart(pdf or ppt) for ADC3644(DDR CMOS or Serial CMOS) vs ADC3664(Serial LVDS).
I thought it was just the difference between DDR CMOS or Serial…
Part Number: ADC3644 Other Parts Discussed in Thread: ADC3643 , I'm wondering if the ADC3644 (and the ADC3643 if it different) is monotonic. The datasheets do not mention monotonic explicitly, but it puts the DNL at 0.5 typical and max of 0.97, which to…
Part Number: ADC3644 I'm having trouble understanding how the output bit mapper works. On page 38 of the ADC3644 data sheet, figure 8-37, gives you an example of the output mapping. The output on the right has an example cell of D0A (0x63, 0x54). I understand…
Part Number: ADC3644 Hello,
I am preparing to read and write to this ADC chip through the SPI interface. But I don't see anywhere in the datasheet (other than the eFuse) that says how long to wait between each command written to the bus. Does it matter…
Part Number: ADC3644EVM Tool/software: Dear Technical Support Team,
I installed HSDC v6.0, but it doesn't include ADC3644.
If I need to install patch, could you provide it?
Best Regards,
