Aftermarket head unit integrated circuits and reference designs

Aftermarket head units with integrated display typically incorporate most infotainment features into one system. This makes the head unit more cost-efficient and easier to install by the original equipment manufacturer (OEM). We have a strong embedded processor and analog portfolio to support your head unit with integrated display designs.

• Typical video interfaces red, green, blue (RGB) parallel, online data interchange (OLDI) or high-definition multimedia interface (HDMI), as well as controls such as I2C, serial peripheral interface (SPI) or general purpose input/output (GPIO).
• Backlight drivers commonly require the boost of voltages and are typically powered off the vehicle battery.
• Converting clock and data lines to low voltage differential signaling (LVDS) helps mitigate external machine interface (EMI).
• Temperature sensing is used to ensure the backlight LEDs do not drive the temperature beyond the specified panel rating.
