Hello everyone and thank you for this good forum.
I have a question, i would like to sample a signal that has a freqeuncy up to 1 MHz with at least 16 Msps and i mean with this that i don't want ADC Chip to has a clock of of 16 MHz so until i read the data from ADC it will be as a result of this 1 Msps.. so i want to read a real time 16 Msps.
I was searching the internet and i found some Chips but all of them are expensive and the cheapsest solution was one of these LTC2162/LTC2161/LTC2160.. and LTC2160 has a clock of 125MHz and so i think,i will be able to read a real 16 Msps or even 25 Msps but can someone find a cheaper solution .. Thanks

What type of system (FPGA?) will be reading the data that fast? A LTC2160 has : full rate CMOS, double data rate CMOS, or double data rate LVDS to a 16-bit read port at the selected Msps.

I will be using 32bit Microcontroller STM32F7.. Thanks for reply
