Bring-up

Startup log

At power-up the FPGA aligns the ADC word boundaries, checks the test patterns on both channels, and reports the first throughput. This is the board’s own terminal output.

kuncu@adc:~ UART
================================
Word alignment on ADC_1 started
Channel 0 before word alignment: FC0F
Channel 1 before word alignment: FC0F
word alignment done status: F
word alignment failed status: C
Channel 0 after word alignment: FFC0
Channel 1 after word alignment: FFC0
================================
Test Pattern Check Started on ADC_0
All test patterns are checked
Total number of errors: 0

ADC_1 Speed: 762.916016 MB/s

Real results, recorded from the board’s UART console during bring-up. The status lines are raw hex values from the alignment routine; the result is in the checks that follow, with zero test pattern errors on both ADCs.

FAQ

Common questions

What is this board?

It is an eight-channel, 12-bit acquisition board sampling at 100 MSPS, designed and built in-house. This page collects the board itself and its key specifications.

Was the board designed entirely in-house?

Yes. The board, its analog front-ends, and its bench bring-up were handled by one team, so the analog, layout, and measurement work stayed in one place.

Can you design a similar board for my application?

Yes. Every engagement starts from your specification: channel count, sample rate, resolution, and host interface. Send your requirements and you will get an approach and a timeline.
