The RTL8305NB-VB-CG Ethernet IC is a 6-by-6mm quad flat no-lead (QFN) package with 48 pins for easy soldering and mounting. It is a low-power Ethernet physical layer (PHY) device that offers advanced features such as auto MDI/MDIX, half/full duplex support, auto-negotiation, and 1Gbps Ethernet. This device also offers a wide range of interface options, including RGMII, MII, RMII, and reverse MII. This part is RoHS compliant and is manufactured by Realtek.The RTL8305NB-VB-CG Ethernet IC supports all the major IEEE 802.3 standards, such as 10Base-T, 100Base-TX, and 1000Base-T. It is also compatible with optional Wake-on-LAN (WOL) and Energy Efficient Ethernet (EEE) functions, which are designed to reduce system power consumption and boost performance when the network is idle. Additionally, this device supports the latest industry standards like IEEE-1588 and priority queuing for packet prioritization. This IC also contains four configurable low-skew clock outputs for driving multiple Ethernet PHYs and digital ASICs, enabling faster time-to-market.The RTL8305NB-VB-CG supports embedded systems and a variety of industrial, automotive, and networking applications. It is designed with a 1.8V input voltage that ensures compatibility with other components in the system as well as helps save power when running multiple Ethernet connections. Furthermore, this device is 10-kV surge-proof, meaning it can handle up to 10kV of voltage without any damage.
