9.2.2 Detailed Design Procedure
Designing in the SN65DP141 requires the following:
- Determine the loss profile on the DP input and output channels and cables.
- Based upon the loss profile and signal swing, determine the optimal configuration for the SN65DP141, to pass electrical compliance (Equalization mode, EQ Gain, DC gain, and AC Gain).
- See Figure 9-2 for information on using the AC coupling capacitors and control pin resistors, as well as for recommended decouple capacitors from VCC pins to ground.
- Configure the TheSN65DP141 using the GPIO terminals or the I2C interface:
- GPIO – Using the terminals EQ_MODE, EQ1, EQ1, and gain.
- I2C – Refer to the I2C Register Maps and the Two-Wire Serial Interface and Control Logic sections for a detailed configuration procedures.
- The thermal pad must be connected to ground.
