KDPOF Gigabit Ethernet transceiver
Gigabit Ethernet in the car is getting into gear: Fabless chipmaker KDPOF (Madrid, Spain) has introduced the KD1053 transceiver chip for plastic optical fiber (POF). The device is designed for use with automotive qualified photonics, including 650nm RCLED, LED, and Si PIN PD that are currently used in existing automotive products, with updated analog optoelectronics/interfaces.

The KD1053 facilitates design at system and board level through its support for multiple host digital interface standards, including RGMII, RMII, MII, SGMII, 1000BASE-X, and 100BASE-X. The chip also provides a Serial Management Interface (SMI). Manufacture is based on a 65-nm CMOS process for best performance, lowest cost, and lowest power for POF.


The KD1053 transceiver is designed to meet the requirements of the key applications for future automotive networks: communication backbone, smart antenna link, infotainment, battery management systems (BMS) and Advanced Driver Assistance Systems (ADAS). With its design, the vendor is aiming at integrating high-speed capabilities in POF ports with a low-cost BOM (Bills Of Materials). Its built-in analog interface simplifies connectivity to Fiber Optic Transceivers (FOT). Examples of products able to incorporate POF ports based on the KD1053 ASSP include ECUs, switches, cameras, and infotainment nodes.

First samples of the GEPOF KD1053 device will be available in August 2017.
