BCM5222KQMG - Dual-Port 10/100 Ethernet PHY | Broadcom
部品番号: BCM5222KQMG ✓ 生産中BCM5222KQMG 概要
An Ethernet PHY is the physical-layer portion of an Ethernet communication system. It converts digital data into signals suitable for transmission over twisted-pair cabling and recovers timing and data from received signals. According to the Broadcom BCM5222 data sheet, the BCM5222 integrates a digital adaptive equalizer, analog-to-digital converter, phase-locked loop, line driver, encoder, decoder, and supporting circuitry in one monolithic CMOS device. It complies with the IEEE 802.3u requirements for Fast Ethernet, including the Media Independent Interface and Auto-Negotiation sections.
The verified distributor listing identifies BCM5222KQMG as a 2/2 full-Ethernet transceiver with PHY functionality and a 100-MQFP package. A separate indexed specification describes the BCM5222 family as a dual-port 10/100BASE-TX Fast Ethernet transceiver. These facts make the part applicable to dual-port embedded networking equipment, but the supplied data does not state the exact PHY-versus-MAC division for every internal function, nor does it provide a complete electrical performance table for this orderable MPN.
Its monolithic integration is significant because it consolidates several receive and transmit signal-chain blocks into one component. The integrated adaptive equalizer supports copper-channel signal conditioning, while the phase-locked loop, converter, line driver, encoder, and decoder form the core transmit and receive implementation described by Broadcom. The supported MII and Auto-Negotiation functions help connect the PHY to an Ethernet MAC through a conventional parallel interface.
Typical application candidates include industrial Ethernet controllers, embedded network appliances, printer and scanner interfaces, network interface cards, and dual-port embedded communication systems. Because the verified excerpts do not provide supply voltage, operating temperature, media reach, cable length, jitter, latency, EMI performance, or exact register compatibility, these specifications must be checked in the manufacturer data sheet before schematic sign-off.
A practical design decision is to preserve the 100-MQFP footprint and verify the exact MII pin assignments before routing. Designers should also check the Broadcom reference design or application guidance for recommended magnetics, termination, crystal or clock requirements, decoupling, and controlled-impedance layout. Those implementation details cannot be inferred solely from the distributor classification.
This page separates verified BCM5222KQMG facts from unavailable orderable-part details and synthesizes sourcing, comparison, and design considerations for engineers. It does not substitute generic Ethernet-PHY claims for missing manufacturer data, helping procurement and hardware teams distinguish confirmed specifications from parameters that still require verification.

主な用途
BCM5222KQMG の用途: 6 件s: Dual-Port Industrial Ethernet Controller, Embedded Network Appliance, Network Interface Card, Industrial Printer Ethernet Interface, Network Security Gateway, Ethernet Communication Module.
Dual-Port Industrial Ethernet Controller
BCM5222KQMG fits a dual-port embedded Ethernet design requiring 10/100BASE-TX physical-layer connectivity and a parallel Media Independent Interface. Its two integrated 10 Mbps and 100 Mbps channels can support two independent copper-network connections where the system already contains a compatible Ethernet MAC. The monolithic receive and transmit circuitry is particularly useful when board area is constrained because the equalizer, ADC, phase-locked loop, line driver, encoder, and decoder are combined on one CMOS die. Engineers must still verify the exact MII pinout, operating-temperature grade, cable reach, isolation requirements, and industrial EMC expectations from the Broadcom documentation.
おすすめ
Embedded Network Appliance
The BCM5222KQMG can serve as the physical-layer front end of an embedded appliance with one or two 10/100 Ethernet ports. A host controller can communicate through the BCM5222 family’s Media Independent Interface while the integrated PHY circuitry handles the copper physical layer. This arrangement avoids implementing separate adaptive equalization, line-driver, and conversion blocks on the system PCB. For an embedded appliance, verify the exact device temperature grade, MII timing, reference-clock requirements, magnetics interface, and PCB layout guidance. The verified data does not specify whether every orderable BCM5222 suffix supports identical internal features.
おすすめ
Network Interface Card
BCM5222KQMG is applicable to a dual-port network interface card or add-in Ethernet module requiring 10/100BASE-TX links. Its two full-duplex channels can support copper ports while the MII interface connects to a local controller, avoiding reliance on an unspecified internal MAC arrangement. The confirmed 100-MQFP (14 x 20 mm) package requires careful escape routing on a multilayer PCB. Before layout approval, engineers should confirm the pin assignments, recommended magnetics, termination network, differential pair geometry, reference design, and EMC target because those details are absent from the supplied excerpts.
おすすめ
Industrial Printer Ethernet Interface
The BCM5222KQMG can support the 10/100 Ethernet connectivity used in industrial printers, scanners, and imaging equipment when a local controller drives the PHY over MII. Its dual-port configuration offers a path to connected-device and service-network links on one board, while 100 Mbps operation is appropriate for ordinary print traffic and management traffic. The integrated CMOS implementation reduces the number of external physical-layer signal-chain blocks. Deployment in an industrial printer still requires confirmation of temperature range, isolated media interface requirements, surge tolerance, EMC compliance, and the exact Broadcom reference layout.
おすすめ
Network Security Gateway
BCM5222KQMG is relevant to a compact security appliance that needs two 10/100BASE-TX copper ports for a local network and management path. The MII connection supports integration with a dedicated Ethernet controller, while the integrated equalizer, ADC, phase-locked loop, line driver, encoder, and decoder provide the physical-layer implementation in one monolithic CMOS part. In a security product, designers should pay particular attention to verified EMI, surge, temperature, and clock requirements, as well as the possibility that an 80 Mbps or 100 Mbps-class PHY may be insufficient for high-throughput inspection workloads.
おすすめ
Ethernet Communication Module
BCM5222KQMG can be implemented in a dedicated dual-port Ethernet communication module that exposes an MII connection to a baseboard or central controller. This arrangement is useful when multiple embedded subsystems need shared copper networking without each subsystem implementing a complete physical-layer circuit. The verified 10 Mbps and 100 Mbps capability covers legacy and Fast Ethernet links, while Auto-Negotiation support can assist endpoint speed selection. The system integrator must validate the MII timing interface, synchronization requirements, package dimensions, magnetics selection, and isolation strategy against the complete manufacturer data sheet.

設計ノート
Treat the BCM5222KQMG as a 100-lead MQFP device and complete escape routing only after downloading the exact Broadcom package drawing. The verified distributor excerpt confirms a 14 x 20 mm MQFP, but it does not provide the pin table or pin-1 orientation. Verify every MII, clock, supply, ground, and analog connection against the manufacturer data sheet. Do not infer missing pin names from a generic BCM5222 board layout.
Use the Broadcom BCM5222 reference design and recommended magnetics when laying out the 10/100BASE-TX channel. The integrated adaptive equalizer and ADC form a sensitive receive path, while the line driver generates the transmit waveform. Keep copper away from the media-side network connection, follow the manufacturer’s differential-pair geometry, provide the specified return path, and verify isolation-component placement. Numerical impedance and magnetics requirements are not present in the supplied data and must not be guessed.
Do not treat a similar BCM5222 suffix as automatically drop-in compatible. The supplied cross-reference material identifies BCM5222KQM as a comparison candidate but does not disclose differences in temperature grade, pinout, qualification, or electrical limits. Before substitution, compare the exact ordering codes, MII assignments, supply-voltage range, operating-temperature limits, package drawing, and lifecycle status. A change in order code can affect procurement or qualification even when the family name is unchanged.
コンプライアンス情報
