DS90UB949A-Q1 2K HDMI-to-FPD-Link III Bridge Serializer

1 Features

3 Description

The DS90UB949A-Q1 is an HDMI-to-FPD-Link III

bridge device which, when paired with the FPD-Link

III DS90UB940-Q1/DS90UB948-Q1 deserializers,

supplies 1-lane or 2-lane high-speed serial streams

over cost-effective, 50-Ω single-ended coaxial, or

100-Ω differential shielded twisted-pair (STP) and

shielded twisted quad (STQ) cables. The device can

serialize an HDMI v1.4b input to support video

resolutions up to 2880x1080 at 60 Hz with 24-bit

color depth.

•

AEC-Q100 qualified for automotive applications:

–

Device temperature grade 2: –40°C to 105°C,

T_A

•

Supports TMDS clock frequencies up to 210 MHz

for 3K (2880x1620) at 30Hz, QXGA (2048x1536),

2K (2880x1080), WUXGA (1920x1200), or

1080p60 with 24-bit color depth

•

Single and dual FPD-Link III outputs, supports

STP or STQ or coax cables

The FPD-Link III interface supports both video and

audio data transmissions, and full duplex

control—including I2C and SPI communication—over

the same differential link. Video data consolidation

and control over two differential pairs can help

decrease the interconnect size, decrease the weight

of the application, and simplify system design. EMI is

minimized by the use of low-voltage differential

signaling, data scrambling, and randomization. In

backward-compatible mode, the DS90UB949A-Q1

supports up to 1920x720 resolution with 24-bit color

depth over a single differential link when the device is

paired with the DS90Ux92x-Q1 deserializers.

High-definition multimedia (HDMI) v1.4b

compatible inputs

•

HDMI-Mode DisplayPort (DP++) inputs

HDMI audio extraction for up to 8 channels

High-speed back channel supporting GPIO up to 2

Mbps

•

Tracks spread spectrum input clock to reduce EMI

I2C (master/slave) with 1-Mbps fast-mode plus

SPI pass-through interface

Backward compatible with DS90UB926Q-Q1,

DS90UB928Q-Q1, and DS90UB924-Q1 FPD-Link

III deserializers

The DS90UB949A-Q1 supports multi-channel audio

received through an external I2S interface. The

device also has an optional auxiliary audio interface.
