Texas Instruments DS90UH949A-Q1 is an HDMI to FPD-Link III bridge device. Paired with the FPD-Link III DS90UH940A-Q1 / DS90UH948A-Q1 deserializer, it can provide high-speed serial streams through single or dual channels. Cost-effective 50 Ohm single-ended coaxial cable or 100 Ohm differential STP and STQ cable. The device can serialize HDMI v1.4b input and support up to 2K video resolution with 24-bit color depth.
The FPD-Link III interface supports video and audio data transmission, full-duplex control, and I2C and SPI communication on the same differential link. Combining video data and controlling two differential pairs reduces the size and weight of the interconnect and simplifies system design. By using low-voltage differential signals, data scrambling and randomization, EMI can be minimized. In backward compatibility mode, the device supports 24-bit color depth of 94x deserializers up to 1080p and 92x deserializers up to 720p on a single differential link.
The device supports HDCP repeater applications and can handle all authentication and encryption functions without the need for an external controller. HDMI audio and video data is decrypted at the input and re-encrypted before sending the data to the FPD-Link III interface.
The device supports multi-channel audio received via HDMI or an external I2S interface. The device also has an optional auxiliary audio interface.
