I use AD6645 evaluation board which has 105 MHz cyrstal to sample analog signal. I send sampled signal to a computer and plot that. The signal below which is at 200 KHz is sampled by AD6645 . The sine wave is generated by Agilent waveform generator…
We design a data acquisition system and noticed an overshoot with a ~3us time constant in the ADC data. It is a small effect but it biases our data quality. I spent some time in identifying the source of the time constant.
The source of the time constant…
The AD6645 I/O are CMOS, ~100MHz, so the trace design will not be so critical as long as they are less than a few inches (<6). You can copy the traces from the layout of the product evaluation boards , The files for the AD6645 are located at…
The EZ-Extender to DSP Supported HSC Evaluation Board list mentions the AD6645/PCB. The AD6645-80/PCBZ and AD6645-105/PCBZ are availible. Will these newer versions work with the EZ-Extender?
Alternatively, could anyone reccomend me an ADC evaluation…

Yes, that's exactly how our AD6645 Eval Brd is typically configured as shown in the attached EVB schematic:
AD6645 DRY output > DR_OUT > BUFLAT(via E1 jumper) > U2/U7 CLOCK
The only difference it seems is that we also route the BUFLAT…
May I know if LVDS of 350mV swing is sufficient to drive the AD6645 differential clock?
