4.1 Hardware Requirements

The Cascade Radar reference design includes:

  • Two AWR2243 devices: an integrated single-chip FMCW transceiver.
  • Power management network using a power management integrated circuit (PMIC) DC/DC supply (LP876242-Q1), wide-Vin Buck DC/DC supply (LM62460-Q1), and Boost DC/DC supply (TPS61379-Q1).
  • Two CAN-FD transceivers (TCAN1043A and TCAN1044A), and Ethernet PHY (DP83TC812-Q1).
  • The reference design also includes devices to assist with onboard emulation and UART emulation over a USB link with the PC and Ethernet Port.
