DS90UH925Q
720p 24-bit Color FPD-Link III Serializer with HDCP
General Description
The DS90UH925Q serializer, in conjunction with the
DS90UH926Q deserializer, provides a solution for secure dis-
tribution of content-protected digital video within automotive
entertainment systems. This chipset translates a parallel RGB
Video Interface into a single pair high-speed serialized inter-
face. The digital video data is protected using the industry
standard HDCP copy protection scheme. The serial bus
scheme, FPD-Link III, supports video and audio data trans-
mission and full duplex control including I2C communication
over a single differential link. Consolidation of video data and
control over a single differential pair reduces the interconnect
size and weight, while also eliminating skew issues and sim-
plifying system design.
The DS90UH925Q serializer embeds the clock, content pro-
tects the data payload, and level shifts the signals to high-
speed low voltage differential signaling. Up to 24 RGB data
bits are serialized along with three video control signals and
up to two I2S data inputs.
The DS90UH925Q serializer has a 31-bit parallel LVCMOS
input interface to accommodate the RGB, video control, and
I2S audio data.
EMI is minimized by the use of low voltage differential signal-
ing, data scrambling and randomization and spread spectrum
clocking compatibility.
The HDCP cipher engine is implemented in the serializer and
deserializer. HDCP keys are stored in on-chip memory.
