Tool/software:
Hi again HSDC team,
I'm using your DS90LVRA2EVM, and I have a 120 MHz differential clock. After soldering directly to to the P/N pairs of my signal, I am only getting a much slower single-ended output at 1.8V setting.
Is there any other measured information from TI that says this can convert 120 MHz signals? Maybe I am using the EVM wrong or my hardware connections may be incorrect?
I have the following setup:
- DC power supply able to supply 2A max, and set at 1.8V
- P2 (VCC)
- P3 (GND)
- Secondary DC power supply to power my main circuit that requires the differential to LVCMOS translation
- 500 MHz oscilloscope
- Shielded 3 GHz SMA connectors
- I split one SMA connector in half and soldered each exposed half to either half of the differential pair
- I used the second SMA cabled to connect to the SMA-BNC adapter, which is then connected to the scope
- SMA-to-BNC connector for scope
Zoomed in to maximize the full resolution of the scope.
Regards,
Michael Ly
