MAX3799
1Gbps to 14Gbps, SFP+ Multirate Limiting
Amplifier and VCSEL Driver
General Description
The MAX3799 is a highly integrated limiting amplifier
and VCSEL driver that operates up to 14Gbps, making
it suitable for Ethernet and Fibre Channel applications.
By providing a selectable data path with a noise-shap-
ing filter, the MAX3799 enables a module with 10G
optics to be fully compliant with both 1000BASE-SR
and 10GBASE-SR specifications. Operating from a sin-
gle +3.3V supply, this low-power integrated limiting
amplifier and VCSEL driver IC enables a platform
design for SFP MSA as well as for SFP+ MSA-based
optical transceivers. The high-sensitivity limiting ampli-
fier limits the differential input signal generated by a
transimpedance amplifier into a CML-level differential
output signal. The compact VCSEL driver provides a
modulation and a bias current for a VCSEL diode. The
optical average power is controlled by an average
power control (APC) loop implemented by a controller
that interfaces to the VCSEL driver through a 3-wire
digital interface. All differential I/Os are optimally back-
terminated for a 50 ? transmission line PCB design.
The use of a 3-wire digital interface reduces the pin
count while enabling advanced Rx (rate selection, LOS
threshold, LOS squelch, LOS polarity, CML output level,
signal path polarity, deemphasis, and fast mode-select
change time) and Tx settings (modulation current, bias
current, polarity, and eye safety control) without the
need for external components. The MAX3799 provides
multiple current and voltage DACs to allow the use of
low-cost controller ICs.
The MAX3799 is packaged in a lead-free, 5mm x 5mm,
32-pin TQFN package.
