General description

The GIGA090 is a high performance, low power,

embeddable single port transceiver featuring all

the physical layer interface functions for Gigabit

Ethernet over 100-meter and above CAT 5 cabling.

100BASE-TX and 10BASE-T modes are also

available, enabling a smooth transition from

current 10/100 networks to 1000Mbps-based

networks.

GIGA090 is based on standard

STMicroelectronics’ 90nm CMOS technology for

low power, low cost and high integration.
