Pin Functions

PIN I/O DESCRIPTION
NAME NO.
RX1n 31 Diff I/O Differential negative input for USB3.1 Downstream Facing port.
RX1p 30 Diff I/O Differential positive input for USB3.1 Downstream Facing port.
TX1n 34 Diff O Differential negative output for USB3.1 downstream facing port.
TX1p 33 Diff O Differential positive output for USB 3.1 downstream facing port.
TX2p 37 Diff O Differential positive output for USB 3.1 downstream facing port.
TX2n 36 Diff O Differential negative output for USB 3.1 downstream facing port.
RX2p 40 Diff I/O Differential positive input for USB3.1 Downstream Facing port.
RX2n 39 Diff I/O Differential negative input for USB3.1 Downstream Facing port.
SSTXp 8 Diff I Differential positive input for USB3.1 upstream facing port.
SSTXn 7 Diff I Differential negative input for USB3.1 upstream facing port.
SSRXp 5 Diff O Differential positive output for USB3.1 upstream facing port.
SSRXn 4 Diff O Differential negative output for USB3.1 upstream facing port.
EQ1 35 4 Level I This pin along with EQ0 sets the USB receiver equalizer gain for downstream facing RX1 and RX2 when USB used.
EQ0 38 4 Level I This pin along with EQ1 sets the USB receiver equalizer gain for downstream facing RX1 and RX2 when USB used.
DCI_DAT 29(1) I/O
(PD)		 When I2C_EN ! = 0, this pin functions as DCI data output Leave open if not used.
DCI_CLK 32(1) I/O
(PD)		 When I2C_EN ! = 0, this pin functions as DCI clock output Leave open if not used.
I2C_EN 17 4 Level I I2C Programming Mode or GPIO Programming Select. I2C is only disabled when this pin is ‘0".
0 = GPIO mode (I2C disabled)
R = TI Test Mode (I2C enabled at 3.3 V)
F = I2C enabled at 1.8 V
1 = I2C enabled at 3.3 V.
A1 14 4 Level I When I2C_EN is not ‘0’, this pin will set the TUSB1042I I2C address.
SSEQ1 3 4 Level I Along with SSEQ0, sets the USB receiver equalizer gain for upstream facing SSTXP/N.
SSEQ0/A0 11 4 Level I Along with SSEQ1, sets the USB receiver equalizer gain for upstream facing SSTXP/N. When I2C_EN is not ‘0’, this pin will also set the TUSB1042I I2C address. If I2C_EN = “F”, then this pin must be set to “F” or “0”.
FLIP/SCL 21 2 Level I When I2C_EN=’0’ this is Flip control pin, otherwise this pin is I2C clock. . When used for I2C clock pullup to I2C master's VCC I2C supply.
CTL0/SDA 22 2 Level I When I2C_EN=’0’ this is a USB3.1 Switch control pin, otherwise this pin is I2C data. When used for I2C data pullup to I2C master's VCC I2C supply.
RSVD1 - 12 9, 10, 12, 13, 15, 16, 18, 19, 24, 25, 26, 27 RSVD Reserved. Leave open.
TEST1 23 2 Level I
(Failsafe)
(PD)		 Test pin. Pull down to GND.
TEST2 2 4 Level I Test pin. Leave open.
VCC 1, 6, 20, 28 P 3.3-V Power Supply
Thermal Pad G Ground
(1) Not a fail-safe I/O. Actively driving pin high while VCC is removed results in leakage voltage on VCC pins.
