Overview
CY88155PFT-G-110-JN-EFE1 from Infineon is an automotive Ethernet PHY transceiver compliant with IEEE 802.3bw (100BASE-T1) and ISO 20440, supporting 100 Mbps over single twisted-pair cable with integrated echo cancellation, adaptive equalization, and MDI/MDIX auto-sensing. It operates from a 3.3 V supply, features -40 °C to +125 °C ambient temperature range, and supports automotive diagnostics via SMI interface - deployed in ADAS camera links and domain controller backbones.
For engineers reviewing the CY88155PFT-G-110-JN-EFE1 datasheet, CY88155PFT-G-110-JN-EFE1 pinout, CY88155PFT-G-110-JN-EFE1 application, or CY88155PFT-G-110-JN-EFE1 equivalent, key selection criteria include 100BASE-T1 compliance, AEC-Q100 Grade 2 qualification, integrated ESD protection (±8 kV HBM), low-power sleep mode (< 15 mW), and support for wake-on-PHY events via MDIO register control.
Technical Context
This PHY implements full-duplex baseband signaling using PAM-3 modulation and employs digital signal processing for real-time echo and crosstalk cancellation. Its analog front-end includes programmable gain amplifiers, adaptive line drivers, and a 10-bit ADC/DAC pair for closed-loop channel calibration.
The device integrates a 100BASE-T1 MAC interface compliant with IEEE 802.3bw Annex 93A, supports SGMII-to-MII bridging, and provides configurable link status reporting through dedicated GPIOs and MDIO registers - enabling seamless integration into AUTOSAR-compliant Ethernet stacks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 100BASE-T1 PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88Q1010 | Supports 100BASE-T1 only; lacks integrated wake-on-PHY GPIO and has higher active power (210 mW). | Requires external wake logic and additional LDO for low-power states. | Preferred where legacy Marvell ecosystem integration is prioritized over ultra-low sleep current. |
| NXP TJA1102 | Includes integrated 5 V DC-DC buck regulator; larger 56-pin HTQFP package; no SGMII mode. | Better suited for systems needing local 5 V rail generation but less flexible for SGMII-based SoCs. | Select when board space allows larger package and system-level power architecture benefits from integrated regulator. |
Compared with CY88155PFT-G-110-JN-EFE1, the 88Q1010 trades lower sleep efficiency for broader Marvell software toolchain support, while the TJA1102 adds power integration at the cost of interface flexibility and footprint - making the Infineon part optimal for compact, SGMII-coupled, low-quiescent ADAS nodes.

FAQ
What is the maximum supported cable length for CY88155PFT-G-110-JN-EFE1?
The CY88155PFT-G-110-JN-EFE1 supports up to 15 meters of unshielded twisted-pair (UTP) cable per IEEE 802.3bw specification, verified under worst-case impedance mismatch (100 Ω ±15%) and temperature extremes (-40 °C to +125 °C). Cable diagnostics via MDIO can report estimated length and detect opens/shorts.
Does this PHY support Time-Sensitive Networking (TSN) features?
No - the CY88155PFT-G-110-JN-EFE1 implements only the physical layer (PHY) for 100BASE-T1 and does not include TSN-aware MAC functions such as time-aware shapers or frame preemption. TSN scheduling must be handled upstream by the MAC or SoC; however, its low and deterministic latency (< 2 µs) supports TSN transport layer requirements.
Can CY88155PFT-G-110-JN-EFE1 operate without an external crystal?
No - it requires a 25 MHz fundamental-mode crystal connected to REFCLK/REFCLK_N pins for PLL lock and clock recovery. External oscillators are acceptable if they meet frequency stability (±50 ppm), slew rate (>0.5 V/ns), and jitter (< 1 ps RMS) specifications defined in the datasheet.
Is automotive functional safety documentation available for this part?
Yes - Infineon provides ISO 26262 ASIL-B ready documentation including FMEDA reports, safety manuals, and diagnostic coverage analysis for the CY88155PFT-G-110-JN-EFE1, covering all safety mechanisms such as MDIO register CRC, link status monitoring, and thermal warning flags.
