- Position independence (vs SN65DP141)
- AUX and HPD snooping (vs SN65DP141)
Design Notes
The TDP142IRNQT operates on a single 3.3 V supply. Place 0.1 Β΅F and 1 Β΅F decoupling capacitors as close as possible to the VCC pins to minimize power supply noise. A bulk capacitor of 10 Β΅F is recommended on the power rail. Ensure the power supply can handle the peak current during equalization changes.
For high-speed differential pairs, maintain controlled impedance (typically 100 Ξ© differential) and keep trace lengths matched. Minimize vias and stubs on the main link lanes. Place the redriver close to the connector or source to maximize signal integrity. Use ground planes under the device and provide a solid ground connection to the exposed pad.
The I2C interface (SCL, SDA) should have pull-up resistors (typically 2.2 kΞ© to 3.3 V). The EQ_CTRL, OUT_SWING, and PRE_EMP pins can be left floating if using I2C control, but if using pin-strap configuration, connect them to VCC or GND through resistors. Ensure the EN pin is properly driven to enable the device.
