Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VCC 1, 6, 20, 28 P 3.3-V Power Supply.
DPEQ1 2 4 Level I DisplayPort Receiver EQ control. This along with DPEQ0 will select the DisplayPort receiver equalization gain. Refer to Table 2 for equalization settings.
RSVD1 3 I Reserved.(1)
RSVD2 4 O Reserved.(1)
RSVD3 5 O Reserved.(1)
RSVD4 7 I Reserved.(1)
RSVD5 8 I Reserved.(1)
INDP0p 9 I DP Differential positive input for DisplayPort Lane 0.
INDP0n 10 I DP Differential negative input for DisplayPort Lane 0.
A0 11 4 Level I When I2C_EN = 0, leave the pin unconnected. When I2C_EN is not ‘0’, this pin will also set the TDP142 I2C address. See Table 4. If I2C_EN = “F”, then this pin must be set to “F” or “0”.
INDP1p 12 Diff I DP Differential positive input for DisplayPort Lane 1.
INDP1n 13 Diff I DP Differential negative input for DisplayPort Lane 1.
DPEQ0/A1 14 4 Level I DisplayPort Receiver EQ control. This along with DPEQ1 will select the DisplayPort receiver equalization gain. Refer to Table 2 for equalization settings. When I2C_EN is not ‘0’, this pin will also set the TDP142 I2C address. See Table 4.
INDP2p 15 Diff I DP Differential positive input for DisplayPort Lane 2.
INDP2n 16 Diff I DP Differential negative input for DisplayPort Lane 2.
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.
INDP3p 18 Diff I DP Differential positive input for DisplayPort Lane 3.
INDP3n 19 Diff I DP Differential negative input for DisplayPort Lane 3.
TEST1/SCL 21 2 Level I When I2C_EN=’0’, pull down with 10k or directly connect to ground. Otherwise this pin is I2C clock. . When used for I2C clock pullup to I2C master's VCC I2C supply.
TEST2/SDA 22 2 Level I When I2C_EN=’0’ , pull down with 10k or directly connect to ground. Otherwise this pin is I2C data. When used for I2C data pullup to I2C master's VCC I2C supply.
DPEN/HPDIN 23 2 Level I
(Failsafe)
(PD)		 DP Enable Pin. When I2C_EN = ‘0’, this pin will enable or disable DisplayPort functionality. Otherwise, when I2C_EN is not "0", DisplayPort functionality is enabled and disabled through I2C registers.
L = DisplayPort Disabled. (Pull-down with 10k resistor)
H = DisplayPort Enabled. (Pull-up with10k resistor)
When I2C_EN is not "0" this pin is an input for Hot Plug Detect (HPD) received from DisplayPort sink. When this HPDIN is low for greater than 2 ms, all DisplayPort lanes are disabled.
AUXp 24 I/O, CMOS This pin along with AUXN is used by the TDP142 for AUX snooping. See the Application and Implementation section for more detail.
AUXn 25 I/O, CMOS This pin along with AUXP is used by the TDP142 for AUX snooping. See the Application and Implementation section for more detail.
RSVD6 26 I/O, CMOS Reserved.(1)
RSVD7 27 I/O, CMOS Reserved.(1)
SNOOPENZ/RSVD8 29(2) I/O
(PD)		 When I2C_EN ! = 0, this pin is reserved. When I2C_EN = 0 , this pin is SNOOPENZ (L = AUX snoop enabled and H = AUX snoop disabled with all lanes active).
OUTDP3p 30 Diff O DP Differential positive output for DisplayPort Lane 3.
OUTDP3n 31 Diff O DP Differential negative output for DisplayPort Lane 3.
HPDIN/RSVD9 32(2) I/O
(PD)		 When I2C_EN ! = 0, this pin is reserved. When I2C_EN = 0, this pin is an input for Hot Plug Detect received from DisplayPort sink. When HPDIN is low for greater than 2ms, all DisplayPort lanes are disabled.
OUTDP2p 33 Diff O DP Differential positive output for DisplayPort Lane 2.
OUTDP2n 34 Diff O DP Differential negative output for DisplayPort Lane 2.
RSVD10 35 I Reserved.(1)
OUTDP1n 36 Diff O DP Differential negative output for DisplayPort Lane 1.
OUTDP1p 37 Diff O DP Differential positive output for DisplayPort Lane 1.
RSVD11 38 I Reserved.(1)
OUTDP0n 39 Diff O DP Differential negative output for DisplayPort Lane 0.
OUTDP0p 40 Diff O DP Differential positive output for DisplayPort Lane 0.
GND Thermal Pad G Ground.
(1) Leave unconnected on PCB.
(2) Not a fail-safe I/O. Actively driving pin high while VCC is removed results in leakage voltage on VCC pins.
