5 - 85 MHz 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
distribution of content-protected digital video within automo-
tive entertainment systems. This chipset translates a parallel
RGB Video Interface into a single pair high-speed serialized
interface. The digital video data is protected using the industry
standard HDCP copy protection scheme. The serial bus
scheme, FPD-Link III, supports full duplex of high speed for-
ward data transmission and low speed backchannel commu-
nication over a single differential link. Consolidation of video
data and control over a single differential pair reduces the in-
terconnect size and weight, while also eliminating skew is-
sues and simplifying 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 the three video control signals and
three I2S inputs.
The DS90UH925Q serializer has a 30-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 both the serializer
and deserializer. HDCP keys are stored in on-chip memory.
