Empowering Gigabit Connectivity: Introducing KD1053, seamlessly aligning with IEEE standards for automotive optical communication over POF.

1 GB | Automotive | Consumer | Industrial


The KD1053 implements the Physical-Coding Sublayer (PCS) and Physical Medium Attachment (PMA) sublayer of a 1000BASE-RHx PHY, compliant with the specifications of the IEEE Std 802.3bvTM-2017 standard for gigabit optical communications over plastic optical fiber (POF).

The KD1053 must be connected to a compatible Fiber Optics Transceiver (FOT), which implements a Physical Medium Dependent (PMD) sublayer and a Medium Dependent Interface (MDI), to form a complete automotive 1000BASE-RHC physical layer.

  • Data Interfaces: Support RGMII v2.0, RMII, MII, SGMII, 1000BASE-X and 100BASE-X standards in the MAC interface
  • Standard: 1000BASE-H Physical Coding Sub-layer (PCS) and the Physical Medium Attachment (PMA) sublayers according to the IEEE Std 802.3bv- 2017
  • Key Features: 1000 Mb/s data interface over Automotive/Industrial grade SI-POF. EMC immune. Low latency 6.2 us latency for 1 Gb/s operation and 1.4 us for 100 Mb/s (local RGMII to remote RGMII)
  • Typical Applications: EMC critical applications, such as industrial Ethernet and automotive connectivity: battery management, safe communications backbones, smart antenna modules, infotainment, lower speed EMC-tight links, autonomous driving safety redundancy, and ADAS sensor interconnection.
  • Package: 56-pin QFN (7 x 7 mm) ROHS package
  • Availability: In production

There is an evaluation kit available for purchase that enables full testing of the KD1053 capabilities in automotive and industrial environments.

The kit is self-contained and includes all necessary components to set up and test 100 and 1000 Mb/s links over POF.

It is based on KDPOF’s SFP-POF electronic board, which allows versatile, auto-grade Lab measurements at extreme operating temperature, radiation, and voltage corners.

The EVB1053AUT-TE-EMC evaluation board is available as a reference design for the KD1053.

It provides guidelines for design and evaluation capabilities for EMC in a flexible platform, enabling product designers to successfully shorten the time-to-market for KD1053-based end products.
