Texas Instruments (TI) recently expanded its FPD-Link III automotive-grade SerDes family with a new module. The DS90UH927Q-Q1 serialiser and DS90UH928Q-Q1 deserialiser 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 DS90UH928Q-Q1 is the industry's only deserialiser to offer automatic cable equalisation, 24bit colour dithering, and white balancing over an LVDS connection. These features enable LCD panels to provide the highest performance, lowest cost, and lowest electromagnetic interference (EMI), compared to competitive solutions.

The 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 per cent and makes them differential to provide the lowest possible EMI.

The DS90UH927Q-Q1 and DS90UH928Q-Q1 can be mixed and matched with other members of TI's FPD-Link III family to address an entire range of car models. For example, the DS90UH928Q-Q1 deserialiser can be combined with theDS90UH925Q-Q1 serialiser, DRA74x "Jacinto 6" automotive processor, and DRV2667 piezo haptic driver for HD touchscreens, while the DS90UH927Q-Q1 serialiser and DS90UH928Q-Q1 deserialiser can be combined with the DRV2667 and other leading graphics processors to form a complete infotainment sub-system. Non-HDCP versions of these SerDes are also available as the DS90UB927Q-Q1 and DS90UB928Q-Q1.
