General Description
The MAX3941 is designed to drive an electro-absorp-
tion modulator (EAM) at data rates up to 10.7Gbps. It
incorporates the functions of a biasing circuit and a
modulation circuit, with integrated control op amps
externally programmed by DC voltages.
The integrated bias circuit provides a programmable
biasing current up to 50mA. This bias current reflects a
bias voltage of up to 1.25V on an external 50
load. The
bias and modulation circuits are internally connected on
chip, eliminating the need for an external bias inductor.
A high-bandwidth, fully differential signal path is internally
implemented to minimize jitter accumulation. When a
clock signal is available, the integrated data-retiming
function can be selected to reject input-signal jitter.
The MAX3941 receives differential CML signals (ground
referenced) with on-chip line terminations of 50
. The
output has a 50
resistor for back termination and is
able to deliver a modulation current of 40mA
P-P
to
120mA
P-P
, with an edge speed of 23ps (20% to 80%
typ). This modulation current reflects an EAM modula-
tion voltage of 1.0V
P-P
to 3.0V
P-P
.
The MAX3941 also includes an adjustable pulse-width
control circuit to precompensate for asymmetrical EAM
characteristics. It is available in a compact 4mm x
4mm, 24-pin thin QFN package and operates over the
-40°C to +85°C temperature range.
