DS90UB948-Q1: HDMI to parallel LVDS

Carlos Silva85

I'm trying to implement an isolated HDMI solution, but given the required bandwidth, I have to first de-serialise the stream into some parallel data bus, where each line can be driven at <100Mhz.

Would the DS90UB948-Q1 suffice for this application?

Hello Carlos,

The UB948-Q1 has an oLDI output not parallel data. If you need a deserializer with RGB parallel outputs then you can use the UB926-Q1. This device works in the range 5 - 85 MHz PCLK.

Thank you.
In regards to your suggestion above, do we have a device to reconstruct the signal back to HDMI?

You can use the TFP401x (Panel Bus Digital receiver). this device converts RGB parallel to HDMI.
