3 TUSB1064RNQ EVM Configuration
This section provides the configuration options available in the TUSB1064RNQ EVM.
3.1 TUSB1064RNQ EVM Default Configuration
Table 1 lists the default configuration pins for the TUSB1064 device. Configuration settings may need to
be optimized depending on the amount of loss of each channel in the system. The EVM is configured to
GPIO mode by default. If I2C configuration is desired, JMP7 (I2C_EN) shunt must be changed to shunt
pins 2-3 (VCC).

JMP Control Configuration
JMP1 Downstream EQ1 SHUNT on pin 2-4 (R – 20k to GND)
JMP2 Downstream EQ0 SHUNT on pin 2-4 (R – 20k to GND)
JMP3 Downstream SSEQ1 SHUNT on pin 2-4 (R – 20k to GND)
JMP4 Downstream SSEQ0 SHUNT on pin 2-4 (R – 20k to GND)
JMP5 DP EQ1 SHUNT on pin 2-4 (R – 20k to GND)
JMP6 DP EQ0 SHUNT on pin 2-4 (R – 20k to GND)
JMP7 I2C_EN SHUNT on pin 1-2 (GND)
J1 FLIP No SHUNT
J2 CTL0 No SHUNT
J3 CTL1 No SHUNT
J4 EN SHUNT on pin 1-2 (PU)
3.2 TUSB1064 Equalization Control
Equalization (EQ) can be controlled through I2C or pin-strapping (see Table 2 ). Each TUSB1064 receiver
lane has individual controls for receiver equalization. Table 3 and Table 4 detail the gain values for each
available combination for downstream, upstream, and all DisplayPort configurations.
