2.1 Setup

Table 3-1 lists the default configurations on each configurable pin when the EVM is provided. These configurations settings need to be further customized by the user to properly account for the amount of loss that can be present in a system. The EVM is configured to having GPIO mode enabled by default. If I2C is desired, then JMP1 can be changed to have pins 1 and 2 connected, and the shunt connecting pin 5 and 6 removed. The EVM comes with I2C VCC set to 3.3V. For 1.8V, an external voltage source needs to be used to connect to pin 2 of JMP5.

Table 2-1 TUSB521-Q1 EVM Default Pin Configuration
Designator Function Default Configuration
JMP1 I2C_EN Shunt on pins 5 and 6 (GPIO mode)
JMP2 FLIP/SCL Shunt on pins 3 and 5 (normal)
JMP3 CTL0/SDA Shunt on pins 1 and 3 (USB enabled)
JMP5 I2C VCC Shunt on pins 1 and 2 (I2C 3.3V)
JMP6 EQ0 Shunt on pins 5 and 6 (0)
JMP7 EQ1 Shunt on pins 5 and 6 (0)
JMP8 SSEQ0/A0 Shunt on pins 5 and 6 (0)
JMP9 SSEQ1 Shunt on pins 5 and 6 (0)
JMP10 EN Shunt on pins 1 and 2 (device enabled)
JMP11 A1 Shunt on pins 5 and 6 (0)
JMP19 Power source select Shunt on pins 2 and 3 (VBUS powered)
JMP21 VBUS Select Shunt on pins 1 and 2 (VBUS to port 1)
SW2 TS3USB221 S Pulled to position 1 and 2 (USB2 Port 1)

For selecting which port users want to use, JMP2, JMP21, and SW2 need to be set up accordingly.

For Port 1, JMP2 (Flip/SCL) needs to have a shunt connecting pins 3 and 5 of the jumper to pull the pin down, JMP21 (VBUS select) needs to have a shunt connecting pins 1 and 2 to send VBUS to port 1, and SW2 (TS3USB221 S) needs to be pulled down connecting pins 1 and 2, sending the USB2 signals to port 1.

For Port 2, JMP2 (Flip/SCL) needs to have a shunt connecting pins 1 and 3 of the jumper to pull the pin up, JMP21 (VBUS select) needs to have a shunt connecting pins 2 and 3 to send VBUS to port 2, and SW2 (TS3USB221 S) needs to be pulled up connecting pins 2 and 3, sending the USB2 signals to port 2.
