Signal Name
Differential transmit clock: Common 625MHz to PHYs.
Differential receive clock: 625MHz from PHY. The differential
receiver clock is required for SGMII. Clock recovery from the
differential SGMII0:2RxD signals is not supported.
Differential receive data.
Differential transmit data.
Reference Clock: 100 MHz differential clock pair.
Note: AC coupling required. See “PCI-E and SATA Reference
Clock AC Coupling Recommendations” on page 100.
Data Receive differential signals.
Note: Must be AC coupled.
Data Transmit differential signals.
Note: Must be AC coupled.
Analog obvservation point for manufacturing test of internal
voltage regulator.
Note: For normal operation, do not terminate.
Connect a 1.37k Ω ± 1% external calibration resistor between
