1.1 General Description

The DS90Ux949A-Q1EVM (Evaluation Module) converts HDMI to FPD-Link III. This kit will demonstrate the functionality and operation of the DS90Ux949A-Q1. The DS90Ux949A-Q1 is an HDMI to FPD-Link III serializer which, in conjunction with the DS90Ux940-Q1/DS90Ux948-Q1 deserializers, takes the data from HDMI serial stream and translates it into either single- or dual-lane FPD-Link III interface. The DS90Ux949A-Q1 supports video resolutions up to 210 MHz for 3K (2880x1620) 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.
