Other Parts Discussed in Thread: ADC-LD-BB The description here says that "It takes a single-ended signal (SMA input) and can drive the I+, I-, Q+ and Q- inputs ...".
I was wondering if this can be used in the reverse direction i.e. given the four I…
Hi Scott
Based on your FFT results and my testing it looks like your performance is being limited by HD2 (folds to 320 MHz) and the Fs/2-HD2 (1280 - 320=960 MHz).
In my testing I am not able to get the standard interleaving spurs (Fs/2-Fin, Fs/4+Fin…
Hi Dan
Here is some preliminary data. I am using the ADC12D1600RFRB evaluation board, with external clock at 1150 MHz, so Fs is 2300MSPS. Fin is at 1797.77MHz adjusted to around -0.5dBFS. I did a first measurement in DESI mode using a lab quality balun…
Hi Juri,
Thanks for including the screen shot; this makes the issue much easier to debug. From this, I can see that you are in DESCLKIQ Mode with the ADC12D1800RFRB. There are two things which are likely a problem with the setup:
1. It is not possible…
Other Parts Discussed in Thread: ADC-LD-BB Hello,
Could you inform me about Balun Board for DESIQCLK Mode, please.
I found some boards (really 3, ADC-WB-BB, ADC-LD-BB and TC1-DESIQ-SBB) but without support this mode.
From TC1-DESIQ-SBB description…
Hi Jim,
Thank you very much for your reply.
To order proper peripheral devices cooperating with ADC0XD1520RF (using ADC08D1520), i would like confirm two points with you.
1. Whether we need external clock and clock trigger port need to be DC-blocked…
Other Parts Discussed in Thread: ADC10D1500 , LMH5401 , LMH3401 , ADC12J2700 I want to drive the ADC10D1500 in DESIQ mode and I have been reviewing the document "Driving the GSPS ADCs in Single-Channel or Dual-Channel Mode for High Bandwidth Applications…
Hi Lei,
We provide a balun board for driving and testing the DESIQ Mode, which uses the TC1-1-13MA+ balun. The schematics, which show the pin connection, are available on the web page.

Hi Gregory,
You can also use DESIQ Mode which is easier to drive than DESCLKIQ Mode and is recommended for your application; see the attached report for additional information about driving modes of the GSPS ADC.

Hi Yang,
Sorry there is not a good way to test this you will have top provide 2 differential signal externally probably from the same source with same length/phase matched cables.
