DESCRIPTION
NAME
NO.
SEL0
58
I, 3.3 V
LVCMOS
The pin selects the mux path for channels 0-3.
L: straight data path – RX[0/1/2/3][P/N] connected to TX[0/1/2/3][P/N] through the
redriver.
H: cross data path – RX[0/1/2/3][P/N] connected to TX[1/0/3/2][P/N] through the
redriver.
Active in all device control modes. 59 kΩ internal pull-down. Note: the pin also triggers
PCIe RX detect state machine when toggled.

L: straight data path – RX[4/5/6/7][P/N] connected to TX[4/5/6/7][P/N] through the
redriver.
H: cross data path – RX[4/5/6/7][P/N] connected to TX[5/4/7/6][P/N] through the
redriver.
Active in all device control modes. 59 kΩ internal pull-down. Note: the pin also triggers
PCIe Rx detect state machine when toggled.

LVCMOS,
open drain
In Pin mode:
Sets receiver detect state machine options as provided in Table 7-3. The pin is
sampled at device power-up only.
In SMBus/I2C mode:
3.3V SMBus/I2C clock. External 1 kΩ to 5 kΩ pullup resistor is required as per SMBus /
I2C interface standard.
