BCM84894MA0KFSBG

BCM84894MA0KFSBG is Broadcom’s high‑speed SerDes PHY/transceiver used to connect ASICs/SoCs to media in networking and storage gear. It provides multiple SerDes lanes with TX/RX paths, clock‑data recovery, equalization, and PHY management (MDIO/I2C), supporting multi‑gigabit data rates for common interfaces. Applications include network switches, NICs, storage controllers, and telecom equipment where a compact, power‑efficient PHY is needed to link MACs to backplanes, copper/fiber media, or PCIe/SAS/SATA links depending on the product family. The MA0KFSBG suffix denotes the specific package, temperature rating, and RoHS‑lead‑free variant, with A0 indicating the revision. For exact lane count, supported protocols, data rates, power, I/O voltage, and pinout, consult the BCM84894 datasheet/product brief or contact Broadcom support.

- Pin count: 216-pin BGA (216-ball package).
- Function: Broadcom BCM84894MA0KFSBG is a quad-port Ethernet PHY (10/100/1000BASE-T) with MAC interface to the host/controller (RGMII/SGMII options).

- Manufacturer: Broadcom Inc. (Broadcom).
- What kind of company: A global semiconductor company that designs, develops, and sells a wide range of chips and related software for networking, data centers, broadband, storage, wireless, and enterprise markets.

BCM84894MA0KFSBG is a high-speed, four‑lane SerDes PHY used in data‑center/server, storage, and networking gear. Typical applications:
- Server motherboards and PCIe expansion cards
- Storage controllers and NVMe/SAS/SATA interfaces
- Network equipment ( switches/routers, NICs, line cards )
- Telecom and enterprise infrastructure
- Embedded/SoC/FPGA designs requiring multiple high‑speed serial links
Concise note: it provides multi‑protocol high‑speed SerDes for PCIe, SATA/SAS, and Ethernet interconnects in these environments.

SBG indicates a Small Ball Grid Array (BGA) package.
