Hi,

Is it possible to have multiple Desirializers for one Serializer or a way of repeating the information to multiple locations.

Thanks

Danny,

I have contacted the apps engineer responsible for these devices and they will take a look at your question. Thanks.

Hi Danny,

I have pulled the figures below from the DS90UB928Q datasheet. The DS90Ux925/6 and DS90Ux927/8 can be placed in repeater mode for a maximum of 9 displays.

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 VDD33 or VDDIO = 3.0V to 3.6V with 4.7kΩ 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 VDDIO with a 10kΩ resistor.

Regards,

Mike
