“Surface mount reflow soldering description” .
The PX1011B (types PX1011B-EL1/G, PX1011BI-EL1/G and PX1011B-EL1/N) is
reported to sporadically produce communication failures in Intel DX58S0-based systems
in which the PCIe transmitter has full Active Power State Management (ASPM) capability,
and particularly when L0s mode is supported.
When the PCIe transmitter goes idle (enters L0s) for the purpose of power saving and
then returns to normal mode (exits L0s and enters L0), the PX1011B receiver PLL may
randomly fail to lock, preventing it from properly interpreting the data being transmitted on
the link. As a result the PX1011B may send symbols to the link device that it cannot
recognize.
This is a L0s exit failure which may prevent the system from recovering and could cause
the PCIe protocol to eventually fail and the link to go down. If this occurs, the PX1011B
stays in the exit failure state indefinitely. The receiver can only be re-initiated by applying a
hard reset to the PHY, returning it to normal mode.
You are strongly advised to disable the L0s mode whenever the PX1011B is used.
