Radar verification baseboard for AWR2243 based on ZU15EG
1. Overview of board card
This board card is independently developed by our company, based on MPSOC series SOC XCZU15EG-FFVB1156 architecture, equipped with two groups of 64-bit DDR4, each with a capacity of 32 Gb, and can run stably at 2400MT / s. In addition, there is 1 channel 10G SFP + fiber interface, 1 channel 40G QSFP fiber interface, 1 channel USB3.0 interface, 1 Gigabit network interface and 1 DP interface. The card has automatic charging sequence and supports various starting modes, such as Nor Flash, EMMC, SD card, etc. The card can be connected to TI four AWR2243 MMWCAS-RF-EVM. Can be used in high speed signal processing. The design meets the industrial-grade requirements.
