•

Guarantees jitter and bit-error-rate performance on optical

and fiber links

Supports legacy 1.0625-GbE and 2.125-GbE applications and

new 4.25-GbE data rates off a single reference clock

frequency

On-chip intelligent diagnostics provides insight to the signal

quality with detection and recovery mechanisms on each

high-speed link

Optimizes channel performance for lower power and signal

detection through on-chip 2-wire control interface

Transmits and receives over long distances of copper cables or

backplanes with 16 levels of programmable pre-emphasis

Provides visual indications on PCBs for link status and

1.0625-GbE, 2.125-GbE, or 4.25-GbE data rate transmissions

Low power design of ~1W with small footprint package in a

13-mm x 13-mm BGA, with 1-mm ball pitch
