Figure 34. FPD-Link Fan-Out Electrical Requirements
8.4.6 Repeater Connections
The Repeater requires the following connections between the Receiver and each Transmitter Figure 35.
1. Video Data – Connect all FPD-Link data and clock pairs
2. I2C – Connect SCL and SDA signals. Both signals should be pulled up to V_DD33 or V_DDIO = 3 V to 3.6 V with
4.7 kΩ resistors.
3. Audio (optional) – Connect I2S_CLK, I2S_WC, and I2S_Dx signals.
4. IDx pin – Each Transmitter and Receiver must have an unique I2C address.
5. REPEAT & MODE_SEL pins — All Transmitters and Receivers must be set into Repeater Mode.
6. Interrupt pin – Connect DS90UB928Q-Q1 INTB_IN pin to the DS90UB927Q-Q1 INTB pin. The signal must
be pulled up to V_DDIO with a 10 kΩ resistor.
