2.1.2 Configuration Jumpers

Multiple jumpers are provided on the EVM for configuration of TDP2004 and also for probe points.

The following is a list of 5-level jumpers which are used to configure the TDP2004: J1, J7, J8, J11, J15, J16, J17, J22, J23, J24, J28, J30, J31,and J32. The jumper position to select between the different levels is detailed in Table 3-1.

Note: The 5-level pins are sampled at power up. Therefore, any change in any 5-level pin state cannot be applied until after power cycling the device.

Table 2-2 Jumpers
JumperDefault PositionDescription
J1Short 2 to 3TEST / SCL

Short 1 to 2: SCL in I2C mode
Short 2 to 3: TEST (J31) pulled down in pin-strap mode.
J11Open3.3V
J15OpenGAIN

In Pin mode: Flat gain(DC and AC) from the input to the output of the device for channels 0-3. The pin is sampled at device power-up only. In SMBus/ I2C mode: 3.3V SMBus/ I2C data. External 1kΩ to 5kΩ pullup resistor is required as per SMBus/ I2C interface standard.

J16Short 2 to 3PD_JUMPER

In pin-strap mode, this jumper alongside PD (J32) determines the state of PD.

J17OpenREAD_EN_N

In SMBus/ I2C Primary mode: After device power up, when the pin is low, the pin initiates the SMBus / I2C Primary mode EEPROM read function. When EEPROM read is complete (indicated by assertion of DONEn low), this pin can be held low for normal device operation. During the EEPROM load process, the signal path of the device is disabled. In SMBus/I2C Secondary and Pin modes, the pin is not used. The pin can be left floating. The pin has internal 1MΩ weak pull-down resistor.

J22Short 1 to 2 (L0)EQ1 / ADDR1 Refer to data sheet for details.
J23Short 1 to 2 (L0)EQ0 / ADDR0 Refer to data sheet for details.
J31Short 1 to 2TEST
In Pin mode: TI test mode. External 1kΩ pull down resistor must be installed.
J32Short 1 to 2PD
Short 1 to 2: PD_JUMPER used to set PD.
Short 2 to 3: HPD is used to set PD.
