Hello,
Could you tell me the level of tension there is in departure of Digital I / O? (3.3V or 5V)
Thank you in advance

| It sounds like you're asking if the voltage on the GPIO pins is 3.3V or 5V? The GPIO Signal pins output (and read) 0 or 5V, and the VCC next to each Signal pin is also 5V supply. Nothing on the Serializer, that users interface to, is 3.3V. Best Regards!

| hi Could you please specify the minimum voltage level that is accepted by GPIO pins(especially digital ones) of the serilizer as low voltage? I am trying to communicate an FPGA card with the serilizer. The outputs of the FPGA provides 3.3V as high voltage. Do I have to use integrated circuits converting 3.3V to 5V? thanks

You might try looking for the PIC controller's datasheet for the I/O pin specs.
Sounds like an interesting project,

The specs says the GPIO will work down to 4.2v, but we have been able to communicate at levels as low at 3.3v in the past (for some older BT modules). So, you *should* be able to talk to the TTL port from your FPGA at 3.3v, but we can't guarantee it. :/
