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.
Main features
◾ Fully standards compliant: IEEE 802.3,
IEEE 802.3u, IEEE 802.3z and IEEE 802.3ab
◾ Advanced Cable Diagnostic Features:
– hard fault detection
– Inter pair short
– Excessive cable mismatch
– Excessive cable cross-talk
◾ BER better than 10 -10 in 1000BASE-T mode,
10 -8 in 100BASE-TX mode, on cat5 cables
exceeding 150 mt of length
◾ Six different operating modes
– 1000BASE-T Full Duplex and 1000BASE-T
Half Duplex
– 100BASE-TX Full Duplex and 100BASETX Half Duplex
– 10BASE-T Full Duplex and 10BASE-T Half
Duplex
◾ Configurable MAC interface: MII, GMII or TBI
◾ Automatic configurable operating mode and
MAC interface
◾ Hardware configurable default operation
◾ Automatic detection and correction of pair
swaps (Auto-MDIX), pair skew and pair polarity
◾ Configuration interface
◾ Interrupt management
◾ On-chip transmit wave-shaping, hybrid circuit
and base line wander compensation
◾ 10KB jumbo frames
◾ Internal, external and remote loop back
◾ Status LED controller
