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.

Functional Description
GIGA090 IP supports three different Ethernet protocols: 10BASE-T, 100BASE-TX and 1000BASE-T, and can be configured to either Full Duplex or Half Duplex mode for each protocol. GIGA090 IP integrates all encoding, decoding, data recovery, clock recovery, scrambling, descrambling, digital adaptive equalization, echo cancellation, crosstalk cancellation, ADC, DAC, line transmission, link integrity, MAC and management interface functions that are required for 10Mb/s, 100Mb/s, and 1000Mb/s data transmission. It can be manually configured, be programmed or automatically determine its operating mode depending on the capabilities of the tranceiver on the opposite end of the link and the capabilities of the cable. The GIGA090 IP consists of 8 functional blocks:

Auto-Negotiation block, which is responsible for advertising the chip's capabilities and establishing the link. Management Register block, which contains all the configuration registers Management Data Interface Physical Coding Sublayer block, which contains the 1000/100/10 Base T sub-blocks Mac Interface. DPMA: Digital Physical Media Attachment, which consists of 1000/100/10 Base T subblocks: Clock Distribution and Reset circuitry. Status LED managment block.
