Single port 10 base-T/100 base-TX PHY transceivers from Micrel

Micrel has released the KSZ8051/8031 family of low-power, small package single-port 10 base-T/100 base-TX Physical Layer Transceivers. The ICs provide the MII or RMII interface to transmit and receive data over standard CAT-5 unshielded twisted pair (UTP) cable or fiber.

These PHY transceivers are made using Micrel's 0.13 µm CMOS technology, which Micrel claim enables power consumption to be reduced by half compared to the prior generation. The devices feature on-chip termination resistors and integrated regulator thus simplifying board layout. The devices enable 10 base-T/ 100 base-TX Ethernet connectivity in digital TVs, IP set top boxes, game console, industrial and automotive applications.

"Energy efficiency and compliance to important green standards such as ENERGY STAR are becoming paramount in the digital home making Micrel's new devices a key enabler for the pervasive adoption of IP connectivity in devices such as Digital TVs, Set-Top-Boxes and media players," noted Wiren Perera, Micrel's director of Ethernet Products. "The low emissions and Micrel's signature high reliability and quality also make these devices suitable for connectivity applications in the fast growing industrial automation and automotive markets."

The KSZ8051/8031 family is fully compliant with IEEE 802.3/802.3u standard thus ensuring that the devices will work with other standards compliant, already deployed devices. These devices operate from a single external power supply of 3.3V with an internal 1.2V regulator and an optional 3.3V, 2.5V and 1.8V VDDIO. Micrel says that the ultra low power design satisfies the green requirement in today's consumer, industrial and automotive Ethernet applications.

Package:
The KSZ8051MLL/FLL comes in a 48-pin LQFP package.
The KSZ8051MNL/RNL comes in a 32-pin QFN package.
The KSZ8031RNL comes in a 24-pin QFN package.

Availability: Sampling now, volume production expected in the third quarter of 2010.Micrel has released the KSZ8051/8031 family of low-power, small package single-port 10 base-T/100 base-TX Physical Layer Transceivers.
