- 240MHz sampling frequency
- 60 dB of dynamic range
- 12 bits for ENOB
- 75 dBFS SNR
- 2.5 Vpp for differential full-scale input
Thanks for sharing the new part (AD9652).
Our operating frequency is between 170 to 220MHz, as per new chip datasheet with these frequencies,
We are looking for meeting parameters (as posted above) at 170 - 220MHz as well. Please suggest if there any other options.
I tried to run your setup of CLK = 240Msps and AIN = 170/220MHz in our AD9652 evaluation board. As far as SNR parameter is concerned, the data on our bench surpass your requirements of 72dBFS, and as for ENOB, it is intermittent around 11.5 but can be improve more by using clean analog input.
Also, we see the lead time of these parts are high and options we have to get in less time?
This question can be answered directly by your local FAE since this is a marketing concern.
Thank you and regards,
I am conducting test on AD7091r-4 using it's evaluation board. I am giving input using function generator of sigilent SDG6052X having 16 bit resolution. I have used external input filter or RC, R= 160ohms and C = 10nF for cutoff frequency of 100KHz to suppress the third harmonic of 300KHz. I am getting good snr of 69 close to 70 claimed by data sheet. But I m unable to get good THD,ENOB,SINAD and SFDR.
Can u recommend the changes with this signal source ?
