Document Table of Contents Transmitter Electrical Idle Generation

The PIPE interface block in Cyclone® 10 GX devices puts the transmitter buffer in an electrical idle state when the electrical idle input signal is asserted. During electrical idle, the transmitter buffer differential and common mode output voltage levels are compliant with the PCIe Base Specification 2.0 for both PCIe Gen1 and Gen2 data rates.

The PCIe specification requires the transmitter driver to be in electrical idle in certain power states.

Note: For more information about input signal levels required in different power states, refer to Power State Management section.
