V
Rx DC differential mode impedance. Impedance during all LTSSM states. When transitioning from a fundamental reset to
detect (the initial state of the LTSSM), there is a 5 ms transition time before the receiver termination values must be met on all
unconfigured lanes of a port.
Required Rx D+ as well as D– DC Impedance (50 ±20% tolerance). Measured at the package pins with a test load of 50 Ω to
GND on each pin. Impedance during all LTSSM states. When transitioning from a fundamental reset to detect (the initial state
of the LTSSM), there is a 5 ms transition time before the receiver termination values must be met on all unconfigured lanes of a
port.
Required Rx D+ as well as D– DC Impedance when the receiver terminations do not have power. The Rx DC common mode
impedance that exists when no power is present or fundamental reset is asserted. This helps ensure that the receiver detect
circuit does not falsely assume a receiver is powered on when it is not. This term must be measured at 300 mV above the Rx
ground.
