Part Number: ADC3421-Q1 Hi Experts, Good day. I need your help with the frequency information for SYSREF pins.
What should be the required frequency?
Keep safe. Regards, Josel
Part Number: ADC3421 Hello,
according to page 43 of the datasheet, the clock can be driven by a single-ended CMOS clock. What signaling levels are best used for this purpose? 1.8V/2.5V/3.3 V LVCMOS/LVTTL?
(SNR degradation due to increased jitter is not…
Part Number: ADC3421 Other Parts Discussed in Thread: OPA4991 Hi,
What is the maximum capacitance I can put on the VCM pin. I am using VCM to bias my ac coupled inputs and I am getting some crosstalk and noise coupling between channels - I believe via…
Part Number: ADC3421 Hi,
I am working on interfacing the ADC3421 to my FPGA using single serial link (1 per output). The ADC is running at 25MSPS and I have had some trouble getting the correct output out of all the different test patterns. I am finding…
Part Number: ADC3441 Other Parts Discussed in Thread: ADC3421 if look at below ENOB, it means there is quite small difference using ADC3421 and ADC3441.
Is it right?
Part Number: ADC3424 Could you tell me the serial interface spec of ADC3424?
According to ADC3421-24.pdf P48 Table6,
fSCLK = 20MHz MAX
tDSU = 25ns min
tDH = 25ns min
But, when fSCLK = 20MHz, this clock time (tSCLK) = 50ns,
and if 50% duty, clock high…
Hi Dan,
I created a timing diagram (using "wavedom" - very helpful tool) to visualize the timing in 2-wire mode, please see below.
Regarding your explanation above on the increasing amplitude of the internal clock - if it is as you descibe…
Part Number: AWR2944 Other Parts Discussed in Thread: ADC3221 , ADC3421
Our Radar have to use 24GHz band, and TI's Radar chip all moved to 60/77 GHz band. So, we have to design our own radar, with functionality and processing power similar to AWR2944…
