1.1
General Description
The DS90UH949A-Q1EVM (Evaluation Module) converts HDMI to FPD-Link III. This kit will demonstrate
the functionality and operation of the DS90UH949A-Q1. The DS90UH949A-Q1 is an HDMI to FPD-Link III
Serializer which, in conjunction with the DS90UH940-Q1/DS90UH948-Q1 Deserializers, takes the data
from HDMI serial stream and translates it into either single- or dual-lane FPD-Link III interface. The
DS90UH949A-Q1 supports video resolutions up to 205 MHz for 2K (2880x1080) 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. In backward-compatible mode, the device
supports up to WXGA and 720p resolutions with 24-bit color depth over a single differential link.
The device supports up to 7.1 audio channels. Audio data received from the HDMI stream is encrypted,
serialized, and sent out on the FPD-Link III stream to a compatible deserializer. Up to 8-channel I2S
interface with maximum bit rate of 192 kHz.
The demo board is not intended for EMI testing. The demo board was designed for easy accessibility to
device pins with tap points for monitoring or applying signals, additional pads for termination, and multiple
connector options.
