Micrel KSZ8041NLJ industrial ethernet PHY

Micrel has introduced the KSZ8041NLJ industrial ethernet PHY. A version of the KSZ8041NL that operates over the extended temperature range of -40 to +125°C, it is a single-supply 10Base-T/100Base-TX physical layer transceiver.

The device provides MII/RMII interfaces to transmit and receive data and uses a mixed signal design to extend signalling distance while reducing power consumption.

The device operates in extremely high temperatures (+125°C) without degrading performance and requires no heat sink.

It supports HP auto MDI/MDI-X to provide the most robust solution for eliminating the need to differentiate between crossover and straight-through cables.

Combined with low power and high performance, it is suitable as a physical layer transceiver for 10Base-T/100Base-TX industrial, motor vehicle and military applications.

Its features include: single-chip 10Base-T/100Base-TX physical layer; fully compliant to IEEE 802.3u standard; low-power CMOS design, power consumption of <180 mW; HP auto MDI/MDI-X for reliable detection and correction for straight-through and crossover cables with disable and enable option; robust operation over standard cables; power down and power saving modes; IVIII interface support; RMII interface support with external 50 MHz system clock; MIIM (MDC/MDIO) management bus to 6.25 MHz for rapid PHY register configuration; interrupt pin option; programmable LED outputs for link, activity and speed; ESD rating (6 kV); single power supply (3.3 V); built-in 1.8 V regulator for core; available in 32-pin MLF package.
