DS90UR905Q/DS90UR906Q:5 - 65 MHz 24-bit Color FPD-Link II Serializer and
Deserializer

The DS90UR905Q/906Q chipset translates a parallel RGB Video Interface into a high-speed serialized interface over a single pair. This serial bus scheme greatly eases system design by eliminating skew problems between clock and data, reduces the number of connector pins, reduces the interconnect size, weight, and cost, and overall eases PCB layout. In addition, internal DC balanced decoding is used to support AC-coupled interconnects.

The DS90UR905Q Ser (serializer) embeds the clock, balances the data payload, and level shifts the signals to highspeed low voltage differential signaling. Up to 24 inputs are serialized along with the three video control signals. This supports full 24-bit color or 18-bit color and 6 general purpose signals (e.g. Audio I2S) applications.
