Part Number: ADC3422 Hi,
I use separate LVDS clock oscillator for ADC3422.
I separate digital power supply and analog power supply for this ADC IC.
So, for oscillator, which power supply should be connected, digital or analog?

Hello,
1) What's the function of SYSREFP & SYSREFM pin? How to use it? Can I leave it NC?
2) Should PCB design control all differential signal by 100ohm/differential impedance?
I am not sure why datasheet 9.3.1 mentioned 50ohm…
Part Number: ADC3422 I implemented the PRBS engine of previous thread some time ago.
Now I'm acquiring samples from a real chip, but these doesn't correspond to numbers generated by PRBS...
On original thread I noted that data value is obtained from…
Part Number: ADC3422 Hello,
In datasheet, the dc accuracy is in below table.
So if using this adc3422 to measure 2V input voltage.
the worst case error will be , 25mV offset and 2%FS = 40mV
so total error will be 25mv+40mV = 65mV.
Let me know…
Part Number: ADC3422 Hi,
for in circuit testing purposes, we would employ the integrated PRBS generator for test sample data, which can be enabled on registers 0A and 0B.
We need to know details about PRBS generator, i.e. its internal structure, polynomial…
Part Number: ADC3422 I don't see anything in the datasheet relating the ADC code to the reference voltage. For example, I set the output to be in binary mode and use a signal-ended input, then INP= Vcm = 0.95. If INM = 0.95, the voltage difference is…
