Detailed Description
The MAX3935 EAM driver consists of a high-speed
modulation driver and an EAM-biasing block (see
Figure 3). The clock and data inputs to the modulation
driver interface with ECL and CML logic levels. The
modulation and bias outputs sink current to V
EE
at
-5.2V.
The modulation output stage is composed of a high-
speed differential pair and a programmable current
source rise times a maximum modulation current of
100mA. The rise and fall times are typically 34ps. The
modulation current is designed to produce an EAM
voltage up to 3.0V
P-P
when driving a 50
module. The
3.0Vp-p results from 100mA through 50
in parallel
with an internal 75
resistor (30
).
Any loading of the EAM module with capacitance
degrades the optical output performance. Because the
BIAS output is connected to the EAM, minimize the par-
asitic capacitance associated with this pad by using an
inductor (L) to isolate the BIAS pin from the EAM.
Clock/Data Input Logic Levels
The MAX3935 is directly compatible with 0V reference
CML. Other logic interfaces are possible with AC-cou-
pling capacitors. For 0V CML of AC-coupled logic, set
V
TT
to 0V. For other DC-coupled differential signals, set
V
TT
to the common-mode input voltage.
