General Description
The MAX3736 is a compact, +3.3V multirate laser driver
for SFP/SFF applications up to 3.2Gbps. The device
accepts differential data and provides bias and modula-
tion currents for driving a laser. DC-coupling to the laser
allows for multirate applications, and reduces the num-
ber of external components.
The wide 5mA to 60mA (85mA AC-coupled) modulation
current range and 1mA to 100mA bias current make the
MAX3736 ideal for driving FP/DFB laser diodes in fiber-
optic modules. The laser current setting can be con-
trolled by a current DAC, a voltage DAC, or a resistor.
Very low power dissipation, small package size, and
reduced component count, make this part an ideal solu-
tion for SFP-module applications.
The MAX3736 is available in a small 3mm x 3mm, 16-pin
thin QFN package. It operates over a -40°C to +85°C
temperature range.

Detailed Description
The MAX3736 laser driver consists of three operational
blocks: a bias current generator, a modulation current
generator, and a high-speed modulation path. The
laser-biasing block includes a monitor output for bias-
sensing purposes. Both the bias and modulation gener-
ating blocks are enabled and disabled by the DIS pin.
The high-speed modulation path provides a 100Ω
differential input resistance.
Bias Current Generator
To maintain constant average optical power, the
MAX3736 is designed to interface to a laser controller
IC. The laser controller IC controls the MAX3736, and
maintains a constant laser power using an automatic
power-control (APC) circuit. A back-facet photodiode,
mounted in the laser package, is used to convert the
optical power into a photocurrent. The laser controller
IC adjusts the laser bias current so the monitor photodi-
ode’s current matches the level programmed by the
user. It does this by adjusting the current sourced by
the MAX3736’s BIASSET pin. The MAX3736 reacts by
increasing or decreasing the laser current at BIAS.
Bias Current Monitor
The MAX3736 features a bias current monitor
(BC_MON). This monitor is realized by mirroring a frac-
tion of the bias current and developing a voltage
across an external resistor connected to ground. For
example, connecting a 100Ωresistor to ground gives
the following relationship:
VBC_MON = (IBIAS / 73) x 100Ω. For compliance, the
voltage on BC_MON must be kept below 1.39V.
Modulation Current Generator
The laser’s modulation amplitude can be controlled by
placing a resistor from MODSET to ground. To set the
modulation amplitude, see the IMOD vs. RMODSET
graph in the
Typical Operating Characteristics
. A more
advanced control scheme employs the use of a laser
controller IC to control modulation current to
stabilize the extinction ratio. For more information on
controlling the extinction ratio, refer to Application

and Extinction Ratio, Part 1, Slope Efficiency and

High-Speed Modulation Driver
The output stage is composed of a high-speed differ-
ential pair and a programmable modulation current
source. The MAX3736 is optimized for driving a 15Ω
load; the minimum instantaneous voltage required at
OUT+ is 0.6V. Modulation current swings up to 60mA
are possible.
To interface with the laser diode, a damping resistor (RD)
is required for impedance matching. The combined
resistance of the series damping resistor and the equiva-
lent series resistance of the laser diode should equal
15Ω. To reduce optical output aberrations and duty-
cycle distortion caused by laser diode parasitic induc-
tance, an RC shunt network might be necessary. Refer to
Application Note 274:
HFAN-02.0: Interfacing Maxim
Laser Drivers with Laser Diodes
for more information.
At high data rates, e.g., 2.5Gbps, any capacitive load at
the cathode of a laser diode degrades optical output per-
formance. Because the BIAS output is directly connected
to the laser cathode, minimize the parasitic capacitance
associated with the pin by using an inductor to isolate the
BIAS pin parasitics from the laser cathode.
In the absence of input data, the modulation current
switches to OUT-, squelching the transceiver output.
Disable
The DIS pin disables the modulation and bias current.
The typical enable time is 2µs for bias current and 1µs
for modulation current. The typical disable time is 200ns
for bias current and 250µs for modulation current. The
DIS pin has a 7.4kΩinternal pullup resistor.
Design Procedure
Programming the Modulation Current
There are three methods for setting the modulation cur-
rent on the MAX3736 laser driver. The current can be
set by using a current DAC, a voltage DAC in series with
a resistor, or by using a resistor connected to GND.
To program the laser modulation current using a cur-
rent DAC, attach the DAC to the MODSET pin and set
the current using the following equation:
To program the laser modulation current using a volt-
age DAC, attach the DAC to the MODSET pin through a
series resistor, RSERIES, and set the current using the
following equation:
To program the laser modulation current using a resis-
tor, place the resistor from MODSET to ground. IMOD
current can be calculated by the following equation:
Programming the Bias Current
There are three methods for setting the bias current on
the MAX3736 laser driver. The current can be set by
using a current DAC, a voltage DAC in series with a
resistor, or by using a resistor connected to GND.
To program the laser bias current using a current DAC,
attach the DAC to the BIASSET pin and set the current
using the following equation:
To program the laser bias current using a voltage DAC,
attach the DAC to the BIASSET pin through a series
resistor, RSERIES, and set the current using the follow-
ing equation:

rent can be calculated by the following equation:

Input Termination Requirements
The MAX3736 data inputs are SFP MSA compliant. On-
chip 100Ω, differential input impedance is provided for
optimal termination (Figure 5). Because of the on-chip
biasing network, the MAX3736 inputs self-bias to the
proper operating point to accommodate AC-coupling.
Applications Information
Data Input Logic Levels
The MAX3736 is directly compatible with +3.3V reference
CML. Either DC or AC-coupling can be used for CML ref-
erenced to +3.3V. For all other logic types, AC-coupling
should be used. DC coupling to CML is fine, but it
negates the squelching function on the modulation path.
Modulation Currents Exceeding 60mA
For applications requiring a modulation current greater
than 60mA, headroom is insufficient for proper operation
of the laser driver if the laser is DC-coupled. To avoid
this problem, the MAX3736 modulation output can be
AC-coupled to the cathode of a laser diode. An external
pullup inductor is necessary to DC-bias the modulation
output at VCC. Such a configuration isolates laser for-
ward voltage from the output circuitry and allows the out-
put at OUT+ to swing above and below the supply
voltage (VCC). When AC-coupled, the MAX3736 modula-
tion current can be programmed from 5mA to 85mA.
Refer to Maxim Application Note
HFAN 02.0: Interfacing
Maxim’s Laser Drivers to Laser Diodes
for more informa-
tion on AC-coupling laser drivers to laser diodes.
Interface Models
Figures 5 and 6 show simplified input and output cir-
cuits for the MAX3736 laser driver.
Layout Considerations
To minimize loss and crosstalk, keep the connections
between the MAX3736 output and the laser as short as
possible. Use good high-frequency layout techniques
and multilayer boards with an uninterrupted ground
plane to minimize EMI and crosstalk.
Exposed-Pad Package
The exposed pad on the 16-pin QFN provides a very low
thermal resistance path for heat removal from the IC. The
pad is also electrical ground on the MAX3736 and must
be soldered to the circuit board ground for proper ther-
mal and electrical performance. Refer to Application
Note 862:
HFAN-08.1: Thermal Considerations of QFN
and Other Exposed-Paddle Packages

information.

Laser Safety and IEC 825
Using the MAX3736 laser driver alone does not ensure
that a transmitter design is compliant with IEC 825. The
entire transmitter circuit and component selections
must be considered. Customers must determine the
level of fault tolerance required by their application.

designed or authorized for use as components in sys-
tems intended for surgical implant into the body, for
