Part Number: ADC3443 SYSREFM LVDS inputs needs an external termination? I’m 90% sure that it doesn’t as there is no mention of termination in the D/Sheet or in the reference design. I was just wondering if you can confirm that the 100R LVDS termination…
Part Number: ADC3443 Hi,
We will use the FPGA's LVDS driver to drive SYSREF.
The output characteristics of this driver are 1.25V common mode voltage and 0.25 ~ 0.6V differential swing.
I realized in past thread that this circuit requires an external…

I’m fairly advanced in designing in the ADC3443 and now looking at the detail on the design.
I came across this PCN (on the Digikey site)

Is this…
Hi Lolo,
The ADC will continue to sample at 14-bit resolution.
The GUI does not have any input to address this issue. There is not a register setting that the 2-Vpp and 1-Vpp corresponds to, but rather this seems to be a physical limitation. The Analog…
Part Number: ADC3443 Hello,
I would like to know how to perform multi chip ADCs synchronization when I'm using only LVDS wires and not JESD204B, and when I'm not using the internal ADC clock divider ?
Thanks for your support
Lolo
Hi Rohit,
We already plan to use a fully differential amplifier to adapt the common mode to the one of the ADC.
The problem here is that the input signal is not fully differential. The P signal goes from 1,7V to 2,7V while the N signal goes from 1,7V…
Part Number: ADC3443 Other Parts Discussed in Thread: ADS6444 Team,
During the bring up of a custom system the digitalized output of the ADC3443 is not as expected, for a given analog input.
Could you please confirm if the sampling is done on the rising…
Part Number: ADC3443 Other Parts Discussed in Thread: ADC3441 Hello
In the ADC3443 datasheet, in the power up chapter on page 58, there is the table 8 which lists the required registers Writes.
You mentioned the addresses 137h, 437h, 537h, 237h twice…
Part Number: ADC32J45EVM Other Parts Discussed in Thread: TSW14J10EVM , ADC3443 Hello Team,
My customer is looking for the ADC3000 GUI which they can use for the device ADC32J45EVM and TSW14J10EVM, Can you share with us the where to find it?
Regards,
Ren…
