Part Number: ADC34J44 Hi Team
Can you help to review the the below circuit used for ADC34J44 input Impedance matching? Customer refer to our EVM's design.
Part Number: ADC34J44 Hi, Team:
When the input signal is greater than 0dbfs, the signal collected by FPGA becomes more spurious, like overflow.
I want to ask what is the maximum input signal allowed by adc34J44.

Hi Team
What is the meaning of 'N' in this link post? the Divide?
Part Number: ADC34J44 Hi,
We are planning to use this JESD interface daughter board with our FPGA.
I want to know the FMC connector pinouts.
Please send me the schematic asap.
Regards,
Harika.
Part Number: ADC34J44 Other Parts Discussed in Thread: ADC32J44 If the PDN is pulled up from power up, is it possible to acess the device through the SPI interface, without first driving the PDN pin low?
Whilst in power down what do the device outputs…
Part Number: ADC34J44 Hi team
As mentioned in Datasheet, Digital output level is CML, if the receiver is just supported LVDC ,if customer can change by impendence matching? How?
Thanks!
Part Number: ADC34J44 Other Parts Discussed in Thread: THS4541 Dear all,
I am thinking use ADC34J44 as in my project.
My application needs a DC coupling.
Is there any recommended diff driver & circuit for this adc, since the evm only has the transformer…
Hi Sanjay,
Is the LVDS output from the FPGA a 1.8V signal? If not, I would suggest using a level translator in order to be in line with the datasheet.

Hi Sanjay,
I have not seen the codes roll over before. Is this happening on all of the channels? Can you please explain this further?
There is an over-range bit for each channel that will indicate an over-range event.
Best Regards,

Lorant,
Please try writing a 0x04 to address 0x15 and see if you notice the current dropping going to the EVM. This enables the global power down.

Jim
