RTL8305NB-VC-CG

RTL8305NB-VC-CG is a single-chip 5-port 10/100M Ethernet switch controller. The device integrates five PHY transceivers supporting 10BASE-T and 100BASE-TX operation, a high-performance non-blocking switch engine, an on-chip SRAM for address lookup, an on-chip SRAM for packet buffering, and a built-in management interface for configuration and management. The switch controller supports a wide range of advanced features, including port-based VLAN, IEEE 802.1Q tag-based VLAN, QoS, bandwidth control, storm filtering, loop detection, and cable diagnostics. It supports auto-negotiation, auto MDI/MDIX crossover detection and correction, polarity detection and correction, and link monitoring. The device is powered by a 1.2V core voltage and 3.3V I/O voltage, and integrates an LDO for generating the 1.2V core voltage. It supports configuration via serial EEPROM or an external management interface. The device is available in a 48-pin QFN package.
