CAD_SNK/DCI_DAT(1) | 29 | I/O
(PD) |
When I2C_EN ! = 0, this pin functions as DCI data output Leave open if not used. When I2C_EN = 0 , this pin is CAD_SNK (L = AUX snoop enabled and H = AUX snoop disabled with all lanes active). |
HPDIN/DCI_CLK(1) | 32 | I/O
(PD) |
When I2C_EN ! = 0, this pin is functions as DCI clock output Leave open if not used. 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 while the AUX to SBU switch will remain closed. |
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. |
SBU1 | 27 | I/O, CMOS | SBU1. This pin should be DC coupled to the SBU1 pin on the Type-C receptacle. A 2-M ohm resistor to GND is also recommended. |
SBU2 | 26 | I/O, CMOS | SBU2. This pin should be DC coupled to the SBU2 pin on the Type-C receptacle. A 2-M ohm resistor to GND is also recommended. |
AUXp | 24 | I/O, CMOS | AUXp. DisplayPort AUX positive I/O connected to the DisplayPort source through a AC coupling capacitor. In addition to AC coupling capacitor, this pin also requires a 100K resistor to GND. This pin along with AUXN is used by the TUSB546A-DCI for AUX snooping and is routed to SBU1/2 based on the orientation of the Type-C. |
AUXn | 25 | I/O, CMOS | AUXn. DisplayPort AUX negative I/O connected to the DisplayPort source through a AC coupling capacitor. In addition to AC coupling capacitor, this pin also requires a 100K resistor to DP_PWR (3.3V). This pin along with AUXP is used by the TUSB546A-DCI for AUX snooping and is routed to SBU1/2 based on the orientation of the Type-C. |
DPEQ1 | 2 | 4 Level I | DisplayPort Receiver EQ. This along with DPEQ0 will select the DisplayPort receiver equalization gain. |
DPEQ0/A1 | 14 | 4 Level I | DisplayPort Receiver EQ. This along with DPEQ1 will select the DisplayPort receiver equalization gain. When I2C_EN is not ‘0’, this pin will also set the TUSB546A-DCI 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 TUSB546A-DCI 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. |
CTL1/HPDIN | 23 | 2 Level I
(Failsafe) (PD) |
DP Alt mode Switch Control 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. H = DisplayPort Enabled. When I2C_EN is not "0" this pin is an input for Hot Plug Detect received from DisplayPort sink. When this HPDIN is Low for greater than 2 ms, all DisplayPort lanes are disabled and AUX to SBU switch will remain closed. |
