ADS58B19EVM: Any output from the board

Adrien Amoros

Part Number: ADS58B19EVM
Other Parts Discussed in Thread: ADS58B19

I am trying to test the evaluation board for the ADS58B19 ADC but it seems impossible to get any output from the chip itself.

I use an LVDS clock from an FPGA board as clock input and 20MHz sinus 1.5Vpp as signal input.

The ADC supply is correct regarding the datasheet.

How can we see if the chip works well and/or is not damaged ?

I tried to request thanks to the GUI software a test pattern but nothing seems to appear on the J5 connector of the board...

Please any suggestion should be very helpful.

Kind regards.

Hi Adrien,

Here is a reference thread that may help you with you issue:

Please first use the clock and input connection per recommended on the EVM user's guide, and you may check the CLKOUT on the ADC output to see if you are able to get a LVDS clock output from the ADC.
