About

Integrated MACsec for in-vehicle networking protection

The BRIGHTLANE™ 88Q120xM features integrated MACsec to safeguard against layer 2 in-vehicle networking threats, securing data exchange on a hop-by-hop basis and preventing attacks such as intrusion, man-in-the-middle, and replay attacks. Manufactured using a standard digital CMOS process, it includes all the active circuitry needed to transmit and receive data over a single balanced twisted pair. The device supports reduced pin count GMII (RGMII) and SGMII for direct connections to MAC/switch ports, along with integrated media dependent interface (MDI) termination resistors that streamline board layout and reduce costs.

Efficient data processing and robust EMI compliance

The BRIGHTLANE™ 88Q120xM is equipped with a voltage regulator to generate all necessary voltages, allowing it to operate from a single 3.3 V supply while supporting 1.8 V, 2.5 V, and 3.3 V LVCMOS I/O standards. Utilizing advanced mixed-signal processing, the device delivers equalization, echo and crosstalk cancellation, data recovery, and error correction at a data rate of 100 Mbps. It ensures robust performance that exceeds electromagnetic interference (EMI) requirements in noisy environments, all while maintaining very low power dissipation.

Benefits

Designed to meet the specific needs of our customers the BRIGHTLANE™ 88Q120cM offers several features and benefits, including:

  • 100 BASE-T1, IEEE 802.3bw-compliant: Automotive Ethernet PHY supports operation over unshielded twisted pair (UTP)
  • Supports IEEE 802.1AE MACsec: MACsec provides layer 2 security
  • OPEN Alliance TC10 sleep mode: As an IEEE and OPEN Alliance TC10 compliant 1000 BASET1 Ethernet PHY, the device supports wake-up and sleep signaling over dedicated I/O pins, as well as through wake-up pulse (WUP), wake-up request (WUR) and low power sleep (LPS) commands
  • Automotive qualified: AEC-Q100, automotive grade 1 (-40 °C to +125 °C)
  • Automotive package: 40-QFN, 6.0 x 6.0 mm, 0.5 mm pitch, wettable flanks
  • Wake on LAN (WoL): Saves system power through magic packet or link change detection
  • Integrated voltage regulators: 3.3 V only operation
  • Integrated passive filter network: Reduced BOM/board space
  • Integrated Virtual Cable Tester: VCT tool used for cable diagnostics
  • Signal quality indicator (SQI): Signal quality indicator (SQI) tool provides signal-to-noise ratio (SNR) data
  • 802.1AS and 1-step PTP: Support for Precision time protocol (PTP)
