TI’s SerDes chips provide a low-EMI, tablet-like experience across all vehicle models from entry-level sedans to luxury SUVs
Texas Instruments (TI) expanded its FPD-Link III automotive-grade SerDes family today with the industry’s most feature-rich chipset. The DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer 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 deserializer to offer automatic cable equalization, 24-bit color 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 percent and makes them differential to provide the lowest possible EMI. Compared to the competition, TI’s FPD-Link family gives system architects a greater number of video sources and displays that can be directly connected to the automotive video network.
Key features and benefits of the DS90UH927Q-Q1 and DS90UH928Q-Q1:
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 deserializer can be combined with the DS90UH925Q-Q1 serializer, DRA74x “Jacinto 6” automotive processor, and DRV2667 piezo haptic driver for HD touchscreens, while the DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer can be combined with the DRV2667 and other leading graphics processors to form a complete infotainment subsystem. Non-HDCP versions of these SerDes are also available as the DS90UB927Q-Q1 and DS90UB928Q-Q1.
Tools and support
Evaluation modules (EVMs) are available today to quickly evaluate both devices. Suggested retail pricing for the DS90UH927QEVM and DS90UH928QEVM is US$299, respectively. IBIS models for the DS90UH927Q-Q1 and DS90UH928Q-Q1 are also available.
Availability, packaging and pricing
The DS90UH927Q-Q1 serializer and DS90UH928Q-Q1 deserializer are available now, priced at US$9.75 each in 1,000-unit quantities. The DS90UH927Q-Q1 is in a 40-pin, 6-mm × 6-mm QFN package, while the DS90UH928Q-Q1 is in a 48-pin, 7-mm × 7-mm QFN package.
