2.2 Configuration Jumpers

Multiple jumpers are provided on the EVM for configuration of TUSB1104 and also for probe points.

Following is a list of 4-level jumpers which are used to configure the TUSB1104: JMP5, JMP6, JMP7, JMP8, JMP9, JMP10, JMP12, and JMP13. The jumper position to select between the different levels is detailed in 4-level Configuration Jumper Settings Table.

Note: 4-level pins are sampled on rising edge of EN pin. Therefore, a change in any 4-level pin state will not be applied until after EN pin is toggled from low to high.

JumperDefault PositionDescription
JMP1OpenCC1. Pin 1 is probe point for CC1
JMP2OpenCC2. Pin 1 is probe point for CC2
JMP3Short 3 to 4FLIP/SCL.
If TUSB1104 is configured for I2C mode (MODE pin (JMP13)) is floating, then jumper is clock for local I2C.
If TUSB1104 is configured for pin-strap mode, then this jumper selects which lane is the config lane.
  • Short 1 to 2: CRX2->SSRX2 and SSTX2->CTX2 is config lane.
  • Short 3 to 4: CRX1->SSRX1 and SSTX1->CTX1 is config lane.
JMP4Short 1 to 2AEQENZ/SDA.
If TUSB1104 is configured for I2C mode (MODE pin (JMP13)) is floating, then jumper is data for local I2C.
If TUSB1104 is configured for pin-strap mode, then jumper selects whether AEQ is enabled or not.
  • Short 1 to 2: AEQ disabled.
  • Short 3 to 4: AEQ enabled.
JMP5OpenSSEQ1/A1.
If TUSB1104 is configured for I2C mode (MODE pin (JMP13)) is floating, then this jumper along with JMP6 will select the 7-bit I2C target address. Refer to TUSB1104 datasheet for details on available I2C target address options.
If TUSB1104 is configured for pin-strap mode, then this jumper along with JMP6 selects EQ settings for SSTX receivers. Refer to TUSB1104 datasheet for details on EQ settings.
JMP6OpenSSEQ0/A0.
If TUSB1104 is configured for I2C mode (MODE pin (JMP13)) is floating, then this jumper along with JMP5 will select the 7-bit I2C target address. Refer to TUSB1104 datasheet for details on available I2C target address options.
If TUSB1104 is configured for pin-strap mode, then this jumper along with JMP5 selects EQ settings for SSTX receivers. Refer to TUSB1104 datasheet for details on EQ settings.
JMP7OpenEQCFG.
If TUSB1104 is configured for I2C mode (MODE pin (JMP13)) is floating, then this jumper must be left floating for normal operation.
If TUSB1104 is configured for pin-strap mode, then this jumper will select EQ options for SSTX receivers and CRX receivers. Refer to TUSB1104 datasheet for details.
JMP8OpenAEQCFG.
Selects upper limit for AEQ. Refer to TUSB1104 datasheet for details.
JMP9OpenCEQ1.
If TUSB1104 is configured for pin-strap mode, then this jumper along with JMP10 selects EQ settings for CRX receivers. Refer to TUSB1104 datasheet for details on EQ settings.
JMP10OpenCEQ0.
If TUSB1104 is configured for pin-strap mode, then this jumper along with JMP10 selects EQ settings for CRX receivers. Refer to TUSB1104 datasheet for details on EQ settings.
JMP11OpenEN.
The EN will enable or disable the TUSB1104.
JMP12OpenVIO_SEL.
Selects whether local I2C interface is at 1.8 V or 3.3 V signalling levels. The default is 3.3 V. Short pins 1 and 2 to select 1.8 V.
JMP13Short 1 to 2MODE.
Selects between pin-strap and I2C mode. The default is pin-strap mode.
  • Short 1 to 2: Pin-strap mode
  • Open: I2C mode.
JMP14OpenSLP_S0#.
JMP15OpenPower for TUSB1104.
Selects whether TUSB1104 is powered from VBUS or 5 V barrel jack. The default is power from USB VBUS. Shorting between position 1 and 2 will select the 5 V barrel jack.
JMP16OpenThe local I2C voltage pull-up option. The default is local I2C pull-ups are connected to TUSB1104's 3.3 V VCC supply. Removing R47 allows for feeding external DC supply for local I2C.
