3 Description
The DS90UH929-Q1 is a HDMI to FPD-Link III bridge
device which, in conjunction with the FPD-Link III
DS90UH926Q-Q1/DS90UH928Q-Q1 deserializers,
provides 1-lane high-speed serial stream over cost-
effective 50Ω single-ended coaxial or 100Ω
differential shielded twisted-pair (STP) cable. It
serializes a HDMI v1.4b input supporting video
resolutions up to WXGA and 720p with 24-bit color
depth. The DS90UH929-Q1 is also compatible with
the DS90UH940-Q1/DS90UH948-Q1 deserializers.
The FPD-Link III interface supports video and audio
data transmission and full duplex control, including
I2C communication, over the same differential link.
Consolidation of video data and control over one
differential pair reduces the interconnect size and
weight and simplifies system design. EMI is
minimized by the use of low voltage differential
signaling, data scrambling, and randomization.
The DS90UH929-Q1 supports HDCP Repeater
applications where all authentication and encryption
functions are handled without the need for an
external controller. HDMI audio and video data are
decrypted at the input and re-encrypted prior to
sending onto the FPD-Link III interface.
The DS90UH929-Q1 supports multi-channel audio
received through HDMI or an external I2S interface.
The device also supports an optional auxiliary audio
interface.
