Description
BCM5461SA3KFBG is Broadcom’s single-port Gigabit Ethernet PHY in a Fine-Pitch FBGA package. It provides the physical layer for 10/100/1000BASE-T networks and connects to a MAC via MII or RMII.
Key points:
- 10/100/1000BASE-T PHY with auto-negotiation and full/half-duplex operation.
- Interfaces to a MAC via MII/RMII; requires external Ethernet magnetics and standard PHY LED pins.
- Packaged in a high-density FBGA (A3K variant) suitable for embedded NICs, motherboards, and network adapters.
- Includes analog front-end/line drivers and typical PHY utilities; designed for Broadcom’s PHY ecosystem.
Usage note:
- For exact electrical specs, pinout, timing, and package dimensions, refer to the BCM5461SA3KFBG datasheet and packaging drawings from Broadcom.
If you need a quick spec snippet or package drawing, I can summarize the official datasheet sections you’re after.
