PCI Express Transmit Differential Data
PCI Express Receive Differential Data
P_RX[x]+ provides the positive differential data receiver
for PCI Express phy[x].
PCI Express Receive Differential Data
P_RX[x]− provides the negative differential data receiver
for PCI Express phy[x].
P_TX[x]+ provides the positive differential data
transmitter for PCI Express phy[x].
PCI Express Transmit Differential Data
P_TX[x]− provides the negative differential data
transmitter for PCI Express phy[x].
These pins provide the serial differential clock. Connect a
75 MHz oscillator with an accuracy of at least ±50 ppm to
these pins. To use a single-ended crystal, tie the crystal to
REFCLK_P and tie REFCLK_N to a resistor termination.
Resistor Reference
This pin provides the analog resistor reference for the
GigaBlaze transceivers. The resistor provides a reference
to calibrate the 50 Ω termination.
Receive Negative Differential Data
RX[x]− provides the negative differential data receiver for
SAS/SATA phy[x].
Receive Positive Differential Data
RX[x]+ provides the positive differential data receiver for
SAS/SATA phy[x].
Transmit Negative Differential Data
TX[x]− provides the negative differential data transmit
signal for SAS/SATA phy[x].
