RTL8305NB-CG中文资料SINGLE-CHIP 5-PORT 10/100M ETHERNET SWITCH CONTROLLER数据手册Realtek规格书

描述 Description

The RTL8305NB is a 5-port 10/100M Ethernet switch controller that integrates memory, five MACs, and five physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.
To simplify the peripheral power circuit, the RTL8305NB integrates one LDO regulator to generate 1.0V from a 3.3V input power.
