GENERAL DESCRIPTION
The TZA3001AHL, TZA3001BHL and TZA3001U are fully
integrated laser drivers for STM4/OC12 (622 Mbits/s)
systems, incorporating the RF path between the data
multiplexer and the laser diode. Since the dual loop bias
and modulation control circuits are integrated on the IC,
the external component count is low. Only decoupling
capacitors and adjustment resistors are required.
• Optional external control of laser modulation and biasing
currents (non-adaptive)
• Automatic laser shutdown
• Few external components required
• Rise and fall times of 120 ps (typical value)
• Jitter <50 mUI (p-p)
The TZA3001AHL features an alarm function for signalling
extreme bias current conditions. The alarm low and high
threshold levels can be adjusted to suit the application
using only a resistor or a current Digital-to-Analog
Converter (DAC).
• RF output current sinking capability of 60 mA
• Bias current sinking capability of 90 mA
• Power dissipation of 430 mW (typical value)
• Low cost LQFP32 plastic package
• Single 5 V power supply.
The TZA3001BHL is provided with an additional RF data
input to facilitate remote (loop mode) system testing.
TZA3001AHL
The TZA3001U is a bare die version for use in compact
laser module designs. The die contains 40 pads and
features the combined functionality of the TZA3001AHL
and the TZA3001BHL.

FUNCTIONAL DESCRIPTION
The RF path is fully differential and contains a differential
preamplifier and a main amplifier. The main amplifier is
designed to handle large peak currents required at the
output laser driving stage and is insensitive to supply
voltage variations. The output signal from the main
amplifier drives a current switch which supplies a
guaranteed maximum modulation current of 60 mA at
pins LA and LAQ. Pin BIAS delivers a guaranteed
maximum DC bias current of up to 90 mA for adjusting the
optical laser output to a level above its light emitting
threshold.
The TZA3001AHL, TZA3001BHL and TZA3001U laser
drivers accept a 622 Mbits/s STM4 Non-Return to Zero
(NRZ) input data stream and generate an output signal
with sufficient current to drive a solid state Fabry Perot
(FP) or Distributed FeedBack (DFB) laser. They also
contain dual loop control circuitry for stabilizing the true
laser optical power levels representing logic 1 and logic 0.
The input buffers present a high impedance to the data
stream on the differential inputs (pins DIN and DINQ).
The input signal can be at CML level of approximately
200 mV (p-p) below the supply voltage, or at PECL level
up to 800 mV (p-p). The inputs can be configured to accept
CML signals by connecting external 50 Ω pull-up resistors
between pins DIN and DINQ to VCC(R). If PECL
compatibility is required, the usual Thevenin termination
can be applied.
Automatic laser control
A laser with a Monitor PhotoDiode (MPD) is required for
the laser control circuit (see Figs 6 and 7).
The MPD current is proportional to the laser emission and
is applied to pin MONIN. The MPD current range is from
100 to 1000 µA (p-p). The input buffer is optimized to cope
with MPD capacitances up to 50 pF. To prevent the input
buffer breaking into oscillation with a low MPD
capacitance, it is required to increase the capacitance to
the minimum value specified in Chapter “Characteristics”
by connecting an extra capacitor between pin MONIN and
VCC(G).
For ECL signals (negative and referenced to ground) the
inputs should be AC-coupled to the signal source.
If AC-coupling is applied, a constant input signal (either
low of high) will bring the device in an undefined state.
To avoid this, it is recommended to apply a slight offset to
the input stage. The applied offset must be higher than the
specified value in Chapter “Characteristics”, but much
lower than the applied input voltage swing.

It should be noted that the MPD current is stabilized, rather
than the actual laser optical output power. Deviations
between optical output power and MPD current, known as
‘tracking errors’, cannot be corrected.
DC reference currents are applied to pins ZERO and ONE
to set the MPD reference levels for laser LOW and laser
HIGH. A resistor connected between pin ZERO and VCC(R)
and a resistor connected between pin ONE and VCC(R) is
sufficient, but current DACs can also be used.
The voltages on pins ZERO and ONE are held constant at
a level of 1.5 V below VCC(R). The reference current
applied to pin ZERO is multiplied by 4 and the reference
current flowing into pin ONE is multiplied internally by 16.
Designing the modulation and bias loop
The optical ONE and ZERO regulation loop time constants
are determined by on-chip capacitances. If the resulting
time constants are found to be too small in a specific
application, they can be increased by connecting external
capacitors to pins TZERO and TONE, respectively.
The reference current and the resistor for the optical ONE
regulation loop (modulation current control) can be
calculated using the following formulae:

Example: A laser with an MPD has the following
specifications: PO = 1 mW, Ith = 25 mA, ηEO = 30 mW/A,
R = 500 mA/W. The term Ith is the required threshold
current to switch-on the laser. If the laser operates just
above the threshold level, it may be assumed that ηEO
around the optical ZERO level is 50% of ηEO around the
optical ONE level, due to the decreasing slope near the
threshold level.

The automatic laser control function can be overridden by
connecting voltage sources to pins TZERO and TONE to
take direct control of, respectively, the bias current source
and the modulation current source. The control voltages
should be in the range from 1.4 to 3.4 V to sweep the
modulation current through the range from 1 to 60 mA and
the bias current through the range from 1 to 90 mA. These
current ranges are guaranteed. Depending on the
temperature and manufacturing process spread, current
values higher than the specified ranges can be achieved.
However, bias and modulation currents in excess of the
specified range are not supported and should be avoided.
The resulting bandwidth for the optical ZERO regulation
loop, without external capacitance, would be:
Currents into or out pins TZERO and TONE in excess of
10 µA must be avoided to prevent damage of the circuit.

Automatic laser shut-down and laser slow start
The laser modulation and bias currents can be rapidly
switched off when a HIGH-level (CMOS) is applied to
pin ALS. This function allows the circuit to be shut-down in
the event of an optical system malfunction. A 25 kΩ
pull-down resistor defaults the input of pin ALS to the
non active state.
It is not necessary to add additional capacitance with this
type of laser.
Data pattern and bit rate dependency of the control
loop
When a LOW-level is applied to pin ALS, the modulation
and bias current slowly increase to the desired values with
the typical time constants of τONE and τZERO, respectively.
This can be used as a laser slow start.
The constants in Equations (1) and (3) are valid, provided
a frequent presence of sufficiently long runs of ‘constant
zero’ and ‘constant one’. The longest run of zeros and
ones, occurring typically within a single loop time period
(τONE and τZERO), must be at least approximately 6 ns
(e.g. as provided by the A1/A2 frame alignment bytes for
STM4/OC12). In practice, it can be witnessed that the
optical extinction ratio will increase if the bit rate is
increased. Therefore it is important to use the actual data
patterns and bit rate of the final application circuit for
adjusting the optical levels.
Bias alarm for TZA3001AHL
The bias current alarm circuit detects and flags whenever
the bias current is outside a predefined range. This feature
can detect excessive bias current due to laser aging and
laser malfunctioning. The maximum permitted bias current
should be applied to pin ALARMHI with an attenuation
ratio of 1500; the minimum to pin ALARMLO with an
attenuation ratio of 300.
Monitoring the bias and modulation current
Although not recommended, the bias and modulation
currents generated by the laser driver can be monitored by
measuring the voltages on pins TZERO and TONE,
respectively. The relations between these voltages and
the corresponding currents are given as transconductance
values and are specified in Chapter “Characteristics”.
The voltages on pins TZERO and TONE range from
1.4 to 3.4 V. The impedance connected at these pins
should have an extremely high value. It is mandatory to
use a CMOS buffer or an amplifier with an input
impedance higher than 100 GΩ and an extremely low
input leakage current (pA range).
1999 Aug 24
Like the reference currents for the laser current control
loop, the alarm reference currents can be set using
external resistors connected between pins ALARMHI
or ALARMLO and VCC(R). The resistor values can be
calculated using the following formulae:

Example: The following reference currents are required to
limit the bias current range between 6 and 90 mA:
To maximize power supply isolation, the MPD cathode on
the laser should be connected to VCC(G) and the laser
diode anode to VCC(B). It is recommended to provide the
laser anode with a separate decoupling capacitor C11.
6 mA
I ALARMLO = -------------- = 20 µA and

The inverted laser driver modulation pin LAQ is generally
not used. To properly balance the output stage, an
equalization network Z1 with an impedance comparable to
the laser is connected between pin LAQ and VCC(B).

I ALARMHI = ----------------- = 60 µA
1500
The corresponding resistor values are:
1.5 V × 1500
R ALARMHI = --------------------------------- = 25 kΩ and
90 mA
All external components should be SMD, preferably of
size 0603 or smaller. The components must be mounted
as close to the IC as possible. It is specially recommended
to mount the following components very close to the IC:
1.5 V × 300
R ALARMLO = ------------------------------ = 75 kΩ
6 mA
• Power supply decoupling capacitors C2, C4 and C6
If the alarm condition is true, the voltage on pin ALARM
goes to HIGH-level (CMOS). This signal could be used, for
example, to disable the laser driver by driving pin ALS
(a latch is needed in between to prevent oscillation).
• Input matching network on pins DIN and DINQ
• Capacitor C7 on pin MONIN
• Output matching network Z1 at the unused output.
Loop mode for TZA3001BHL
Grounding bare die
In the loop mode the total system application can be
tested. It allows for uninhibited optical transmission
through the fibre front-end (from the photodiode through
the transimpedance stage and the data and clock recovery
unit, to the laser driver and via the laser back to the fibre).
It should be noted that the optical receiver used in
conjunction with the TZA3001BHL must have a loop mode
output in order to complete the test loop.
In addition to the separate VCC domains, the bare die
contains three corresponding ground domains. Isolation
between the GND domains is limited due to the finite
substrate conductance.
Mount the die on a, preferably large and highly conductive,
grounded die pad. All pads GND have to be bonded to
the die pad. The external ground is thus optimally
combined with the die ground, avoiding ground bouncing
problems.
A HIGH-level on pin ENL selects the loop mode. By default
pin ENL is pulled at LOW-level by a 25 kΩ pull-down
resistor.
Layout recommendations
Power supply connections
Layout recommendations for the TZA3001AHL and
TZA3001BHL can be found in application note “AN98090
Fiber optic transceiverboard STM1/4/8, OC3,12,24,
FC/GE”.
Three separate supply domains [labelled VCC(B), VCC(G)
and VCC(R)] are used to provide isolation between the
high-current outputs, the PECL or CML inputs, and the
monitor photodiode current input. The three domains
should be individually filtered before being connected to a
central VCC (see Figs 6 and 7). All supply pins need to
be connected. The supply levels should be equal and in
accordance with the values specified in
Chapter “Characteristics”.

Notes
1. Remarks to the supply current:
a) The value for ICC does not include the modulation and bias currents through pins LA, LAQ and BIAS.
b) Typical value for ICC refers to, but does not include, IMOD = 30 mA and IBIAS = 45 mA.
c) The maximum value of ICC refers to, but does not include, IMOD = 60 mA and IBIAS = 90 mA.
2. Remarks to the power dissipation:
a) The value for Ptot includes the modulation and bias currents through pins LA, LAQ and BIAS.
b) The typical value for Ptot is the on-chip dissipation with IMOD = 30 mA and VLA = VLAQ = 2 V, IBIAS = 45 mA and
VBIAS = 1 V and typical process parameters.
c) The maximum value for Ptot is the on-chip dissipation with IMOD = 60 mA and VLA = VLAQ = 2 V, IBIAS = 90 mA and
VBIAS = 1 V and worst case process parameters.
3. The minimum value of the capacitance on pin MONIN is required to prevent instability.
4. The reference currents can be set using a resistor connected between pins ONE or ZERO and VCC
(see Section “Automatic laser control”). The corresponding ZERO level MPD current range is from 24 to 260 µA.
The ONE level MPD current range is from 96 to 1040 µA.
5. The specified transconductance is the ratio between the modulation current at pins LA or LAQ and the voltage at
pin TONE, under small signal conditions.

6. The specified transconductance is the ratio between the biasing current at pin BIAS and the voltage at pin TZERO,
under small signal conditions.
7. The values indicate the guaranteed interval, i.e. the lowest attainable output current is always lower than 3 mA and
the highest output current always higher than 60 mA.
8. The voltage rise and fall times can be larger, due to capacitive effects. Specifications are guaranteed by design and
characterization. Each device is tested at full operating speed to guarantee the RF functionality.
9. Measured in a frequency band from 250 kHz to 5 MHz, according to “ITU-T Recommendation G.813”.
The electrically generated (current) jitter is assumed to be less than 50% of the optical output jitter. The specification
is guaranteed by design.
10. The values indicate the guaranteed interval, i.e. the lowest output current always is less than 2.5 mA and the highest
output current is always more than 90 mA.
11. The response time is defined as the delay between the onset of the ramp on pin ALS (at 10% of the HIGH-level) and
the extinction of the bias current (at 10% of the original value).
12. The reference currents can be set by using a resistor between VCC(R) and pins ALARMLO or ALARMHI;
see Section “Bias alarm for TZA3001AHL” for detailed information. The corresponding range of low-bias thresholds
is between 1.8 and 19.5 mA. The high-bias threshold range is from 9 to 97.5 mA.

SOLDERING
TZA3001AHL; TZA3001BHL;
TZA3001U
If wave soldering is used the following conditions must be
observed for optimal results:
Introduction to soldering surface mount packages
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
Reflow soldering
The footprint must incorporate solder thieves at the
downstream end.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Wave soldering
Manual soldering
Conventional single wave soldering is not recommended
for surface mount devices () or printed-circuit boards with
a high component density, as solder bridging and
non-wetting can present major problems.
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
To overcome these problems the double-wave soldering
method was specifically developed.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.

BARE DIE DISCLAIMER
All die are tested and are guaranteed to comply with all data sheet limits up to the point of wafer sawing for a period of
