3 说明
DP83822 是一款超稳健、低功耗单端口 10/100Mbps 以太网 PHY，旨在用于恶劣的工业环境。DP83822 提供通过标准双绞线电缆发送和接收数据或者连接到外部光纤收发器所需的所有物理层功能。此外，DP83822 还可通过标准 MII、RMII 或 RGMII 接口灵活地连接到 MAC。
为了便于使用，DP83822 提供了集成电缆诊断工具、内置自检和环回功能。该器件能够凭借其快速下行链路检测和强制模式下的自动 MDIX 功能支持多条工业现场总线。
DP83822 提供了一种出色的可靠方案来降低功耗，具体将通过 EEE、WoL 和其他可编程节能模式来实现。
DP83822 是一个功能丰富的引脚到引脚可升级选项，适用于 TLK105、TLK106、TLK105L 和 TLK106L 10/100 Mbps 以太网 PHY。
DP83822 采用 32 引脚 5.00mm × 5.00mm VQFN 封装。
