Hello,

I'm trying to setup a homodyne detector https://www.thorlabs.com/thorproduct.cfm?partnumber=PDB480C-AC,

Your link is no longer valid. Are you having an issue with this device?

Dear Jim,

I intend to buy the ADS54J60EVM. However, I'm not sure if that ADC board is fully compatible with an RF detector from thorlabs (the PDB480C-AC), this because the RF signal at detector output that will be connect to the ADS54J60EVM is an AC signal with voltage ranging from -1V to +1V approximately.

The ADS54J60EVM board is able to discretize an RF AC-Signal with negative voltages?

Best regards

Nuno

This should be no problem as the analog inputs are AC coupled and the device has internally biasing to a common mode voltage of 2V . You may have to add some attenuation as the recommended maximum input for these pins is 1.9V p-p differential or 0.95V per pin.

Jim

Dear Jim,

thank you for your help.

One more question, is the ADS54J60 fully compatible with the TSW1400EVM?

The TSW1400EVM includes software to connect it to the PC? And can we import the data from TSW1400EVM to Matlab?

best regards

Nuno,

No, it is not. You will need either the TSW14J56EVM, the TSW14J57EVM or the TSW14J50EVM. These are the three capture cards that have JESD204B capability.

The TSW1400EVM only supports CMOS and LVDS interfaces. With all of these boards, software is included (HSDC Pro Software GUI) and you can import data into MATLAB.

Jim

Dear Jim,

with the TSW14J50EVM I can collect samples from the ADS54J60EVM at 1 GSPS?

Moreover, it is possible to collect samples bellow 250 MSPS?

Sorry for interrupt your work, but I'm not an expert on this topic.

Best regards

Nuno

Nuno,

You can collect data at 1Gsps with the TSW14J50. Per the data sheet, the minimum sample rate for this ADC is 250Msps. You can probably collect data below this but it is not guaranteed per the data sheet.

Dear Jim,

The voltage range of the ADS54J60EVM can be dynamically adjusted? For instance decreasing the Vpp from 1.9 to 1, concentrating the number of bits in a much narrow range.

Finally, the TSW14J50EVM, ADS54J60EVM, and the HSDC Pro Software GUI are compatible with windows 10?

Nuno,

Question #1 answer is no and question #2 answer is yes for all of these.

Dear Jim,

Thank you very much for you answers. We will now proceed to the purchase of the SW14J50EVM and ADS54J60EVM boards.

Best regards

Dear Jim,

The TSW14J50EVM connects to the PC via USB 2.0, right?

In that case, and considering that I'm using the ADS54J60EVM, the ADC data acquisition is much higher than the download data from usb connection between the TSW14J50EV and the PC, how can I download the data in an almost real-time between the TSW14J50EV and the PC?

best regards

Nuno

You cannot. See the last post I sent.
