15 years agoStratix IV differential LVPECL Ibis model
Hi
i wanted to simulate a differential LVPECL output using ibis models. The models i've found only include LVPECL inputs, but the stratix 4 handbook says, that there are LVPECL outputs too: --- Quote Start --- In Stratix IV devices, the LVPECL I/O standard is supported on input clock pins on column and row I/O banks. LVPECL output operation is not supported in Stratix IV devices. --- Quote End --- So what model do I have to use? Thanks for your help. Thomas5 Replies

right, you'll need to use a high speed transceiver with PCML 1.4V or 1.5V

For this speed you need to read section about dedicated Gigabit transceivers.

I'm afraid your right...
My problem is: I need a 4Gbps serial output and I don't know what I/O Standard on the Stratix 4 or Stratix 5 supports that. I read the sections in the handbooks but it didn't bring me forward. - Altera_Forum

not sure i follow, doesn't the last sentence say there aren't LVPECL outputs?
