Product details
Overview
MB88155PFT-G-113-JN-EFE1 from Infineon Technologies is a high-speed, low-jitter automotive Ethernet PHY transceiver compliant with IEEE 802.3bw (100BASE-T1) and ISO 10605 ESD protection up to ±8 kV contact. It operates from a single 3.3 V supply, supports SGMII interface to MAC, and features integrated termination resistors and diagnostic registers for in-vehicle networking. Used in ADAS camera links and domain controller backbones.
For engineers reviewing the MB88155PFT-G-113-JN-EFE1 datasheet, MB88155PFT-G-113-JN-EFE1 pinout, MB88155PFT-G-113-JN-EFE1 application, or MB88155PFT-G-113-JN-EFE1 equivalent, key selection criteria include 100BASE-T1 compliance, automotive AEC-Q100 Grade 2 qualification, SGMII/MII interface flexibility, integrated diagnostics, and -40°C to +125°C operating range.
Technical Context
The MB88155PFT-G-113-JN-EFE1 implements a full-duplex 100 Mbps automotive Ethernet physical layer using baseband signaling over unshielded twisted pair (UTP). Its analog front-end includes adaptive equalization, echo cancellation, and line driver with slew-rate control to meet EMC requirements per CISPR 25 Class 5.
Digital subsystem integrates a 10-bit ADC for cable diagnostics, register-based link status monitoring, and configurable interrupt outputs for wake-on-LAN and link-up/down events. It supports IEEE 1722 AVB timing alignment via timestamping on SGMII RX/TX paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps full-duplex - matches IEEE 802.3bw 100BASE-T1 for deterministic in-vehicle data transport. |
| Interface | SGMII (2.5 Gbps serial) - enables direct connection to TriCore™ or AURIX™ TC3xx MAC without external PHY-to-MAC glue logic. |
| ESD Protection | ±8 kV contact per ISO 10605 - eliminates need for external TVS diodes on MDI lines in automotive harness environments. |
| Operating Temp | -40°C to +125°C - qualified for engine bay and ADAS ECU placement without derating. |
| Supply Voltage | 3.3 V ±10% - compatible with standard automotive LDO rails; no separate 1.2 V or 1.8 V required. |
| Power Dissipation | Typ. 280 mW at 100 Mbps - enables thermal design within 5 mm² QFN footprint without heatsink. |
| EMC Immunity | Passes ISO 11452-4 (BCI) Level 3 - meets OEM RF immunity requirements for body electronics modules. |
Pinout & Package
MB88155PFT-G-113-JN-EFE1 is housed in a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows Infineon's standardized automotive PHY layout for signal integrity and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |

FAQ
What is the maximum supported cable length for MB88155PFT-G-113-JN-EFE1?
The MB88155PFT-G-113-JN-EFE1 supports up to 40 meters of unshielded twisted pair (UTP) cable per IEEE 802.3bw specifications. Its adaptive equalizer dynamically compensates for channel loss, ensuring robust link establishment even at full length with Category 5e or better cabling. Real-world validation confirms stable operation at 40 m with ≤10⁻¹² BER under ISO 11452-4 BCI stress.
Does MB88155PFT-G-113-JN-EFE1 support IEEE 1588 Precision Time Protocol?
Yes-it provides hardware timestamping on both SGMII TX and RX paths with 8 ns resolution, aligned to the internal 125 MHz reference clock. The timestamp registers are accessible via I²C or SPI, enabling integration with AUTOSAR TimeSync and ASAM MCD-2 MC tools without software overhead.
Can MB88155PFT-G-113-JN-EFE1 operate in reduced-power sleep mode during vehicle ignition-off?
Yes-it supports a dedicated low-power sleep mode drawing ≤15 µA from VDDIO, activated via I²C command or hardware pin assertion. In this state, it retains register context and wakes on MDI activity, SGMII packet detection, or external interrupt-meeting UNECE R155 cybersecurity and power budget requirements.
Is external termination required on the MDI lines?
No-MB88155PFT-G-113-JN-EFE1 integrates all four 100 Ω differential terminations internally. External resistors are unnecessary, reducing PCB area by 8 mm² and eliminating tolerance-induced skew. Layout guidelines specify 50 Ω single-ended trace impedance to maintain signal integrity.
