Texas Instruments Debuts DS90UH927Q-Q1 Serializer, DS90UH928Q-Q1 Deserializer

Texas Instruments DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer chipset

Texas Instruments introduced the DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer. The new TI FPD-Link III chipsets deliver uncompressed high-definition (HD) digital video and audio to touchscreen LCD panels in a vehicle’s central information display and rear passenger seats. The DS90UH927Q-Q1 is in a 40-pin, 6mm x 6mm QFN package, while the DS90UH928Q-Q1 is in a 48-pin, 7mm x 7mm QFN package. The DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer are available now for $9.75 each in 1,000-unit quantities.

The new chipset supports high-bandwidth digital content protection (HDCP), and a direct connection to LVDS input sources and displays, including the OpenLDI (LVDS digital interface) standard. This reduces the number of signal lines by 68 percent and makes them differential to provide the lowest possible EMI.

The DS90UH928Q-Q1 is the industry’s only deserializer to offer automatic cable equalization, 24-bit color dithering, and white balancing over an LVDS connection. The features enable LCD panels to provide the highest performance, lowest cost, and lowest electromagnetic interference (EMI), compared to competitive solutions.
