Texas Instruments DS90UB988-Q1 FPD-Link IV to OpenLDI Deserializer
Texas Instruments DS90UB988-Q1 4K FPD-Link IV to OpenLDI Bridge Deserializer, in conjunction with an FPD-Link IV serializer, the chipset receives a high-speed serialized interface over low-cost 50Ω coax or STP/STQ cables. The DS90UB988-Q1 supports an OpenLDI (10 LVDS data lanes + 2 clocks) interface with video up to 420MHz PCLK. This feature provides a bridge between sources such as GPUs to connect to existing LVDS-based displays or application processors.
The FPD-Link IV interface supports audio and video data transmission and full duplex control, including GPIO and I2C data over the same link. Consolidating video and control data over FPD-Link IV lanes reduces the interconnect size and weight and simplifies system design. EMI is minimized by using low-voltage differential signaling, data scrambling, and randomization. In backward-compatible FPD-Link III mode, the Texas Instruments DS90UB988-Q1 supports up to 2K resolutions with 24-bit color depth over a single/dual link.
