3 Description
The DS90UH949-Q1 is a HDMI to FPD-Link III bridge
device which, in conjunction with the FPD-Link III
DS90UH940-Q1/DS90UH948-Q1
deserializers,
provides 1-lane or 2-lane high-speed serial streams
over cost-effective 50Ω single-ended coaxial or 100Ω
differential shielded twisted-pair (STP) cables. It
serializes a HDMI v1.4b input supporting video
resolutions up to WUXGA and 1080p60 with 24-bit
color depth.
The FPD-Link III interface supports video and audio
data transmission and full duplex control, including
I2C and SPI communication, over the same
differential link. Consolidation of video data and
control over two differential pairs 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. In backward compatible mode, the
device supports up to WXGA and 720p resolutions
with 24-bit color depth over a single differential link.
The DS90UH949-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 DS90UH949-Q1 supports multi-channel audio
received through HDMI or an external I2S interface.
The device also supports an optional auxiliary audio
interface.
