Gigabit Ethernet Transceiver

ET1011C

Gigabit Ethernet transceiver fabricated on a single CMOS chip.
Features LSI TruePHY technology.
Packaged in either a 128-in TQFP, an 84-pin MLCC, or a 68-pin MLCC.
Built on 0.13µm technology for low-power consumption and application in server and desktop NIC cards.

ET1011C is a pin-compatible replacement for the ET1011 device
Commercial and industrial temperature versions available.

ET1011C uses an oversampling architecture
to gather more signal energy from the communication channel than possible with traditional architectures
Offers better signal-to-noise ratio (SNR), and thus improved BER
Advanced timing algorithms are used to enable operation over a wider range of cabling plants
