The DS90UB929-Q1 is an HDMI to FPD-Link III bridge device which, in conjunction with the FPD-Link III DS90UB926Q-Q1/DS90UB928Q-Q1 deserializers, supplies 1-lane high-speed serial stream over cost-effective 50-Ω single-ended coaxial or 100-Ω differential shielded twisted-pair (STP) cable. It serializes an HDMI v1.4b input supporting video resolutions up to WXGA and 720p with 24-bit color depth. The DS90UB929-Q1 is also compatible with the DS90UB940-Q1/DS90UB948-Q1 deserializers. The FPD-Link III interface supports video and audio data transmission and full duplex control, including I2C communication, over the same differential link. The consolidation of video data and control over one differential pair can reduce the interconnect size and weight and can simplify system design. EMI is minimized by the use of low-voltage differential signaling, data scrambling, and randomization. The DS90UB929-Q1 supports multi-channel audio received through HDMI or an external I2S interface. The device also supplies an optional auxiliary audio interface.
