General Description
The MAX3798 is a highly integrated limiting amplifier
and VCSEL driver designed for 1x/2x/4x/8x Fibre
Channel transmission systems at data rates up to
8.5Gbps as well as for 10GBASE-SR transmission sys-
tems at a data rate of 10.3125Gbps. Operating from a
single +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
Ω transmission line PCB design.
The use of a 3-wire digital interface reduces the pin
count while enabling advanced Rx (mode selection,
LOS threshold, LOS squelch, LOS polarity, CML output
level, signal path polarity, slew-rate control, deempha-
sis, and fast mode-select change time) and Tx settings
(modulation current, bias current, polarity, programma-
ble deemphasis, eye-crossing adjustment, and eye
safety control) without the need for external compo-
nents. The MAX3798 provides multiple current and volt-
age DACs to allow the use of low-cost controller ICs.
The MAX3798 is packaged in a lead-free, 5mm x 5mm,
32-pin TQFN package.
