Part Number: ADS4122 Tool/software: Hi,
I have uni-polar signal (0-2V) inserted to FDA (INP) to drive the ADS4122.
The ADC have Differential input voltage of 2 Vpp and VCM of 0.95V.
from the data sheet:
The analog input consists of a switched…
Part Number: ADS4122 Tool/software: Hi,
The digital input of the ADC didn't have standard voltage level.
The FPGA VOH/VOL at 1.8V didn't support the ADC VIH/VIL.
How ever, the FPGA level is define in +2/-2 ma current drive.
There are no definition…
Part Number: ADS4122 Tool/software: Hi team,
Can I know the CLKOUT behavior when reset is applied?
1. When RESET-pin is high, does this IC still output clock from CLKP/M to CLKOUTP/M with buffer?
2. When software reset (by register) is applied,…
Part Number: ADS4122 Hi,
I have analog ground and digital ground on the board.
do I need to connect the DRGND to the analog ground or the digital ground.
I usually connect the the digital ground of converter to the analog ground plane but in this…
Part Number: ADS4122 Hi,
I will using LVDS clock driver to drive the clock input of the ADS4122.
do I need 100 termination?
in the DS of 4122 I find the followed:
pls. advise

Part Number: ADS4122 Hi team,
Figure 112 of the datasheet shows that when single ended clock is used, VCM and VCLKM are shorted with 0.1uF capacitor. But there is no detail explanation for this connection.
Just to make sure, is it necessary to connect…

Dear TI support,
could you please answer to my question (see below)? you have blocked the old thread without answering and explaining why you have blocekd the thread.
Thank you!

Part Number: ADS4122 Dear Ti support,
in the ADS4122 Datasheet it is suggested to select "mode 2" to enhance the performance for input frequencies above 230MHz (Register address = 4Ah, register data = 01h ).
What does this enhancement actually mean…

HI PERF MODE can be selected by register.
What is the difference between HI PERF MODE and Default performance?
Is the reason in the same as the ADS4149 ? Thanks.

Part Number: ADS4122 Hello together,
at the moment wer are busy designig and ADC application using a part of the ADS41xx familiy interfacing with a FPGA.
Problem is that a DDR3- Memory must be connected to the FPGA at the same bank. So there is no…
