NXP’s New Automotive Ethernet Product Portfolio

NXP Semiconductors has launched product portfolio for automotive Ethernet that builds on BroadR-ReachT, which is an automotive standard defined by theOPEN Alliance industry group. NXP’s automotive portfolio features two product families: Ethernet transceivers (TJA1100) and Ethernet switches (SJA1105).

The Ethernet PHY TJA1100 supports automotive low power modes. The systems sleep when the engine is off. However, the Ethernet PHY stays partially powered and wakes up the system only when there is network activity.NXP_AutomotiveEthernet

Transceivers (TJA1100):

  • Compliant with the OPEN Alliance BroadR-Reach (OABR) standard (IEEE: 100BASE-T1)
  • Designed via an automotive development flow
  • 6 × 6 mm² HVQFN package with minimal external component count
  • Supports low-power modes to save battery life
  • Automotive grade ESD and EMC

NXP’s SJA1105 Automotive Ethernet Switch uses Deterministic Ethernet technology to guarantee message latency in applications such as autonomous driving, where deterministic communication is vital for reasons of operational efficiency or functional safety. Deterministic Ethernet supports the trend toward increasing bandwidth requirements of up to one gigabit, while ensuring high reliability in networked control systems and high availability in fail-operational applications. It comprises several standards, including Ethernet (IEEE 802.3), Time-Triggered Ethernet (SAE AS6802) as well as Audio Video Bridging (AVB), and Time-Sensitive Networking (TSN).

Digital Switch (SJA1105):

  • Five-port automotive Ethernet Switch supporting up to 1-Gb network speed
  • Layer 2 Store and Forward Switch
  • MII/RMII/RGMII Interface
  • Port Mirroring and VLAN support (IEEE 802.1Q and IEEE 802.1P)
  • AVB and TSN support
  • Enables Deterministic Ethernet solutions

TJA1100 Ethernet transceivers are available in prototype samples. They will enter mass production in late 2015. SJA1105  Ethernet Switches are available upon request.
