3 說明
DP83822 是一款超穩健、低功耗單端口 10/100Mbps 以太網 PHY，旨在用于惡劣的工業環境。DP83822 提供通過標準雙絞線電纜發送和接收數據或者連接到外部光纖收發器所需的所有物理層功能。此外，DP83822 還可通過標準 MII、RMII 或 RGMII 接口靈活地連接到 MAC。
為了便于使用，DP83822 提供了集成電纜診斷工具、內置自檢和環回功能。該器件能夠憑借其快速下行鏈路檢測和強制模式下的自動 MDIX 功能支持多條工業現場總線。
DP83822 提供了一種出色的可靠方案來降低功耗，具體將通過 EEE、WoL 和其他可編程節能模式來實現。
DP83822 是一個功能豐富的引腳到引腳可升級選項，適用于 TLK105、TLK106、TLK105L 和 TLK106L 10/100 Mbps 以太網 PHY。
DP83822 采用 32 引腳 5.00mm × 5.00mm VQFN 封裝。
