Gbit Ethernet transceiver is for automotive applications

An integrated automotive transceiver, the Gigabit Ethernet POF (Plastic Optical Fibre), or GEPOF, KD1053 is the first integrated automotive transceiver that implements the physical layer of Gigabit Ethernet over POF, says KDPOF.

It is optimised for low power and small footprint and transmits data at 1000/100Mbit/s on standard SI-POF, MC-POF, or PCS, according to 1000BASE-RH (IEEE 802.3bv). It meets the requirements of carmakers by providing high connectivity with flexible digital host interface, low latency, low jitter, and low linking time.

The KD1053 has been 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 analogue optoelectronics/interfaces. The transceiver supports different standards for the host digital interface. This simplifies the system and board level designs, such as RGMII, RMII, MII, SGMII, 1000BASE-X, and 100BASE-X, says the company. It also provides a Serial Management Interface (SMI). Manufacture is based on a 65-nm CMOS process.

The transceiver fulfills the requirements of the POF automotive market such communications backbone, smart antenna link, infotainment, battery management systems (BMS) and advanced driver assistance systems (ADAS).

A built-in analogue interface simplifies connectivity to fibre optic transceivers (FOT), for use in engine control units (ECUs), switches, cameras, and infotainment nodes.

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