The Broadcom BCM5248UA4IQLEG is an octal (8-port) Fast Ethernet transceiver designed for 10BASE-T, 100BASE-TX, and 100BASE-FX operation. It integrates eight independent physical layer interfaces in a single chip, making it ideal for multi-port Ethernet switches and routers. The device supports both full-duplex and half-duplex modes and includes HP Auto-MDIX for automatic cable crossover correction. It also features Advanced CableChecker diagnostics for fault identification. Key electrical specifications include a core supply voltage of 1.8V, I/O voltage of 2.5V, and low power consumption of 200 mW per port (1.6 W total for 8 ports). The transceiver offers a Serial Media Independent Interface (SMII) and Source Synchronous SMII (SSSMII) for connection to MAC layers. It is compliant with IEEE 802.3 and includes IEEE 1149.1 JTAG support. The device is available in a QFP or BGA package option, with body dimensions of 14 mm x 20 mm. The I-TEMP variant supports an industrial temperature range of -40°C to +85°C. This PHY is optimized for use with Broadcom's StrataSwitch family and is suitable for cost-effective Fast Ethernet applications.
The operating temperature range is -40°C to +85°C, inferred from the I-TEMP designation.
The device is available in QFP or BGA package options.
RoHS3 compliance is indicated but unverified.
It supports 10BASE-T and 100BASE-TX/FX, i.e., 10/100 Mbps.
It has 8 ports.
Typical power consumption is 200 mW per port, totaling 1.6 W for 8 ports.
It uses Serial Media Independent Interface (SMII) and Source Synchronous SMII (SSSMII).
