The Keysight APM0100E is a 100 Mb/s media converter that bridges automotive Ethernet (100BASE-T1) and standard Ethernet (100BASE-TX), enabling direct PC-to-ECU communication for node simulation and diagnostics. The device integrates a BroadR-Reach PHY (BCM89810) with a four-wire 10/100 Mb PHY to translate between automotive and standard Ethernet protocols.
– Technical Specifications
• Data Rate: 100 Mb/s
• Automotive Ethernet Interface: Molex Mini50 jack, 100BASE-T1 (BroadR-Reach)
• Standard Ethernet Interface: RJ-45 jack, 100BASE-TX
• PHY: One-port BroadR-Reach transceiver (BCM89810) and four-wire 10/100 Mb transceiver
• Operation Modes: Auto-configuration with automatic master/slave role assignment on BroadR-Reach side; supports 10 Mb/s or 100 Mb/s negotiation on standard Ethernet side; full-duplex capable
• Power: Mini-USB port supply
• Status Indicators: Activity/link LEDs on both PHY interfaces
– Key Features
• Automatic speed negotiation—adapts to 10 Mb/s or 100 Mb/s devices on standard Ethernet side
• BroadR-Reach master/slave auto-configuration eliminates manual setup
• Full-duplex operation for simultaneous bidirectional data transfer
• Compact USB form factor for lab and field deployment
• Dual-PHY architecture handles protocol translation transparently
– Typical Applications
• PC-based automotive ECU testing and diagnostics
• Node simulation in 100BASE-T1 automotive networks
• Bridge between development PCs and BroadR-Reach-equipped hardware
• Validation of automotive Ethernet implementations
– Compatibility & Integration
The APM0100E connects standard PC Ethernet ports to automotive Ethernet ECUs without requiring protocol-aware software. Supports legacy 10 Mb/s devices and modern 100 Mb/s systems through automatic negotiation. Molex Mini50 connector enables direct attachment to production and prototype automotive Ethernet hardware.
