LVTTL with the Red Pitaya Extension Connectors
Posted: Thu Apr 28, 2022 6:34 pm
Hello,
I am interested in using my Red Pitaya with a device that uses 5V TTL where the Red Pitaya is only sending signals to the device. From the 7 series users guide, (ug471) it is stated HR banks are capable of using LVTTL, which would be desirable in my case. However the red pitaya extension connector page states that the extension connector pins use LVCMOS33, and the further specification I've found on the forums (post by Crt Valentincic) only discusses using different differential IO standards on E1 and E2. Does anyone have any insight onto if I can use LVTTL with the extension connector pins? I believe I should be able to, but wanted to see if the forum has any insight. Thank you for your time.
