Single-chip 14G VCSEL driver and dual-path limiting amplifier

A 3-wire digital interface provides a wide range of programmable features to optimize performance. Programmable receive functions include data rate, LOS threshold, LOS squelch, LOS polarity, CML output level, signal-path polarity, slew-rate control, deemphasis, and mode-select change time. Programmable transmit functions include modulation current, bias current, polarity, deemphasis, eye-crossing adjustment, and eye safety control.

The MAX3799 is fully specified for operation over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, and is available in a 5mm x 5mm, 32-pin TQFN package.
