2.2.3 Display
This reference design supports dual display output: cluster display and HUD display. Cluster display is a
1920 × 720 OpenLDI LCD display, and the DRA71x automotive processor renders 60 fps cluster graphics.
An optional HUD output is available through an HDMI interface.
2.2.4 Class-D Audio Amplifier
This reference design supports single zone audio output for warning chimes with a TAS2005 Class-D
amplifier. The TAS2505 device is a low-power digital input speaker amp with support for 24-bit digital I2S
data mono playback. The outputs are placed on the design to connect speakers.
2.2.5 OpenLDI Serializer
This reference design uses a DSC90C189 serializer to convert RGB output from the DRA71x automotive
processor to dual OpenLDI output to drive the cluster display at 1920 × 720 resolution. The DS90C189-Q1
is a low-power bridge for automotive applications that reduces the size of the RGB interface between the
host application processor and the display.
2.2.6 CAN
This reference design supports CAN interface using a TCAN1043. This reference design also enables
wake-up from CAN and Wake Input using a TCAN1043 Transceiver.
2.2.7 Ethernet
Ethernet interface is supported on this reference design to enable content from other subsystems such as
navigation content from a head-unit to be displayed on the cluster display. A DP83TC811R-Q1 Ethernet
Phy is used to interface with the DRA71x automotive processor where content sent over the Ethernet
interface is processed.
