High speed ADC for DSO....

[davorin]

Asked in the DSO project already but got lost somehow (o;

Have now the choice between Maxim and ADI high-speed converters for hooking it up to an FPGA...

Any other good vendor supplying ADCs with samplerates > 250 Msamples/sec?

I even find tek TDS220 use national adc chip!

 

[davorin]

Yeah..we know that..but it´s not an "off-the-shelf" product!!

You can use two moderate ADCs interleaved (working in time-sharing).
I know that it is not what you asked,but it is an option.

ADCs interleaved is a good way,you can use fpga to realize it and it can reduce you systerm cost.

For professional systems, this is not an option. Remember that you won't find two ADCs with identical parameters in analog section. These differences will induce amplitude and linearity errors in the resulted waveform.
