The DP83TC811-Q1 device is an IEEE 802.3bw-compliant automotive PHYTER™ Ethernet physical layer transceiver. The device provides all physical layer functions needed to transmit and receive data over unshielded single twisted-pair cables. The device provides xMII flexibility with support for standard MII, RMII, RGMII, and SGMII MAC interfaces.

This device includes the Diagnostic Tool Kit, providing an extensive list of real-time monitoring tools, debug tools and test modes. Within the tool kit is the first integrated electrostatic discharge (ESD) monitoring tool. The tool is capable of counting ESD events on both the xMII and MDI as well as providing real-time monitoring through the use of a programmable interrupt. Additionally, the DP83TC811-Q1 includes a pseudo random binary sequence (PRBS) frame generation tool, which is fully compatible with internal loopbacks, to transmit and receive data without the use of a MAC. The DP83TC811-Q1 is housed in a 6.00mm × 6.00mm, 36-pin VQFN wettable flank package.

TIDA-020047 — 適用於汽車 4D 成像雷達的雙裝置 mmWave 串接參考設計

此汽車雷達參考設計為串接 76-GHz 至 81-GHz 雷達感測器模組。其中包含 AWR2243 裝置的雙裝置串接陣列和 AM2732R 雷達處理器。在此串接雷達配置中，主要裝置會將 20-GHz 本機振盪器 (LO) 訊號分配至主要和次要裝置，讓這兩個裝置能以單一射頻 (RF) 收發器的形式運作。如此即可支援多達 6 個傳輸 (TX) 和 8 個接收 (RX) 天線元件，因此在多輸入多輸出 (MIMO) 虛擬陣列中總共可提供 48 個虛擬通道。
