Entry-level head unit display audio with Jacinto™ 6 entry reference design


Design files


Based on TI's Jacinto™ DRA71x processor, this automotive reference design focuses on system-level cost savings. The 6 layer design reduces PCB costs through an optimized via breakout scheme, integration of key features and an optimized power distribution network. Functionality can be added or removed based on the end-product requirements. This design targets applications such as infotainment and reconfigurable digital cluster; and supports HDMI, USB3.0/2.0, TAS6424 Digital Class D Amplifier, and FPD-Link interface and multiple other features. It includes a 12V input with a single PMIC. In addition, a Linux, Android, or QNX based software development kit is included.

  • TI Jacinto DRA71x processor with integrated features help customers design cost effective, feature rich, entry level (display audio) infotainment and cluster systems
  • ARM Cortex-A15 based processor with 600MHz, 800MHz, and 1GHz speeds, as well as 3D/2D graphics, C66x DSP and Cortex M4 options
  • Processor Software Development Kit (SDK) for Linux, Android, and QNX development
  • Cost saving features include 6 layer hardware design, rear view camera support, tuner integration with software defined radio, Class D amplifier and multi zone audio support
  • Includes TI's TPS65919 power management IC and TAS6424 Class D audio amplifier
