explain

Ds90ub949-q1 is an HDMI to FPD link III bridge device. It can be used with the FPD link III ds90ub940-q1 / ds90ub948-q1 deserializer to provide single channel or dual channel high-speed serial flow through the cost-effective 50 Ω single ended coaxial cable or 100 Ω differential shielded twisted pair (STP) cable. The device can serialize HDMI v1.4b input, and can support WUXGA and 1080p60 video resolution (24 bit color depth).

The FPD link III interface supports video and audio data transmission and full duplex control (including I2C and SPI communication) through the same differential link. The integration of video data and control through two differential pairs can reduce the size and weight of the interconnect and simplify the system design. Electromagnetic interference (EMI) is reduced to a greater extent by using low-voltage differential signaling, data sequencing and random generation. In backward compatibility mode, the device can support WXGA and 720p resolution (24 bit color depth) on a single differential link.

Ds90ub949-q1 supports receiving multi-channel audio through HDMI or external I2S interface. The device also provides an optional auxiliary audio interface.
