Generate 70MHz signal with 5 voltage levels
Posted: Tue Jul 04, 2017 9:09 pm
I'm working on my own communication protocol for a research project. As a start I want to emulate the Gigabit Ethernet protocol which has 2 properties:
-- Uses at least 5 voltage levels to encode information
-- Operates on a wavelength of ~70MHz+
I have a few questions:
1) What are good FPGAs or programmable devices that operates and can generate and modulate 70MHz signals?
2) Since GPIO pins only produce two voltage levels (0V and high), would a voltage translator be a good option to produce 5 different voltage levels? If not what are some techniques I can use to achieve this?
