DS90UH927Q
5MHz - 85MHz 24-bit Color FPD-Link III Serializer with HDCP
General Description
The DS90UH927Q serializer, in conjunction with a
DS90UH928Q or DS90UH926Q deserializer, provides a so-
lution for secure distribution of content-protected digital video
within automotive entertainment systems. This chipset trans-
lates a FPD-Link video interface into a single-pair high-speed
serialized interface. The digital video data is protected using
the industry standard High-Bandwidth Digital Content Protec-
tion (HDCP) copy protection scheme. The FPD-Link III serial
bus scheme supports full duplex, high speed forward channel
data transmission and low-speed back channel communica-
tion over a single differential link. Consolidation of audio,
video, and control data over a single differential pair reduces
the interconnect size and weight, while also eliminating skew
issues and simplifying system design.
The DS90UH927Q serializer embeds the clock, content pro-
tects the data payload, and level shifts the signals to high-
speed differential signaling. Up to 24 RGB data bits are
serialized along with three video control signals, and up to four
I2S data inputs.
The FPD-Link data interface allows for easy interfacing with
data sources while also minimizing EMI and bus width. EMI
on the high-speed FPD-Link III bus is minimized using low
voltage differential signaling, data scrambling and random-
ization, and dc-balancing.
The HDCP cipher engine is implemented in both the serializer
and deserializer. HDCP keys are stored in on-chip memory.
