GENERAL DESCRIPTION
The TZA3044 is a high gain limiting amplifier that is
designed to process signals from fibre optic preamplifiers
like the TZA3043 and TZA3023. It is pin compatible with
the NE/SA5224 and NE/SA5225 but with extended power
supply range, and needs less external components.
Capable of operating up to 1.25 Gbits/s, the chip has input
signalleveldetectionwithauser-programmablethreshold.
The data and level detection status outputs are differential
outputs for optimum noise margin and ease of use.
The TZA3044B has the same functionality as the
TZA3044, but with TTL compatible status outputs
(pins ST and STQ), and TTL compatible JAM input.

FUNCTIONAL DESCRIPTION
The TZA3044 accepts up to 1.25 Gbits/s data streams,
with amplitudes from 2 mV (p-p) up to 1.5 V (p-p)
single-ended. The input signal will be amplified andlimited
to differential PECL output levels (see Fig.1).
The input buffer A1 presents an impedance of
approximately 4.5 kΩ to the data stream on the inputs DIN
and DINQ. The input can be used both single-ended and
differential, but differential operation is preferred for better
performance.
Because of the high gain of the postamplifier, a very small
offset voltage would shift the decision level in such a way
that the input sensitivity decreases drastically. Therefore a
DC offset compensation circuit is implemented in the
TZA3044, which keeps the input of buffer A3 at its toggle
point in the absence of any input signal.
An input signal level detection is implemented to check if
the input signal is above the user-programmed level.
The outcome of this test is available at the PECL
outputs ST and STQ (TTL for the TZA3044B). This flag
can also be used to prevent the PECL outputs DOUT and
DOUTQ from reacting to noise in the absence of a valid
input signal, by connecting pin STQ to pin JAM. This
guarantees that data will only be transmitted when the
input signal-to-noise ratio is sufficient for low bit error rate
system operation.
PECL logic
The logic level symbol definitions for PECL are shown in
Fig.4.
TZA3044; TZA3044B
If AC coupling is used to remove any DC compatibility
requirement, the coupling capacitors must be large
enough to pass the lowest input frequency of interest.
For example, 1 nF coupling capacitors react with the
internal 4.5 kΩ input bias resistors to yield a lower −3dB
frequency of 35 kHz. This then sets a limit on the
maximum number of consecutive pulses that can be
sensed accurately at the system data rate. Capacitor
tolerance and resistor variation must be included for an
accurate calculation.
DC-offset compensation
A control loop connected between the inputs of buffer A3
andamplifier A1 (see Fig.1) will keep theinputof buffer A3
at its toggle point in the absence of any input signal.
Because of the active offset compensation which is
integrated in the TZA3044, no external capacitor is
required. The loop time constant determines the lower
cut-off frequency of the amplifier chain, which is set at
approximately 850 Hz.
Input signal level detection
The TZA3044 allows for user-programmable input signal
leveldetectionand can automatically disable the switching
of the PECL outputs if the input signal is below a set
threshold. This prevents the outputs from reacting to noise
in the absence of avalid input signal, and insures that data
will only be transmitted when the signal-to-noise ratio of
the input signal is sufficient for low bit-error-rate system
operation. Complementary PECL (TTL forthe TZA3044B)
flags (pins ST and STQ) indicate whether the input signal
is above or below the programmed threshold level.
Input biasing
The inputs, pins DIN and DINQ, are DC biased at
approximately 2.1 V by an internal reference generator
(see Fig.5). The TZA3044 can be DC coupled, but AC
coupling is preferred. In case of DC coupling, the driving
source must operate within the allowable input signal
range (1.3 V to V
than a few millivolts should be avoided, since the internal
DC offset compensation circuit has a limited correction
range.

CCA
The input signal is amplified and rectified before being
compared to a programmable threshold reference. A filter
isincluded to prevent noise spikes from triggeringthe level
detector. This filter has a nominal 1 µs time constant and
additional filtering can be achieved by using an external
capacitor between V
impedance nominally is 25 kΩ). The resultant signal is
then compared to a threshold current through pin RSET.
This current can be set by connecting an external resistor

Example: Detection should occur if the differential voltage
of the input signals drops below 4 mV (p-p). In this case, a
reference current of 0.0018 × 0.004 = 7.2 µA should flow
into pin RSET. This can be set using a current source or
simply by connecting a resistor of the appropriate value.
The resistor must be connected between V

The hysteresis is fixed internally at 3 dB electrical. In the
example of above, a differential level below 4 mV (p-p) of
the input signal will drive pin ST to LOW, and an input
signal level above 5.7 mV (p-p) will drive pin ST to HIGH.
A function is provided to automatically disable the signal
transmission when the chip senses that the input signal is
below the programmed threshold level. This function can
be put into operation by connecting pin JAM with pin STQ.
When the input signal is below the programmed threshold
level, the data outputs are then forced to a predetermined
state (pin DOUT = LOW and pin DOUTQ = HIGH).
Response time of the input signal level detection circuit is
determined by the time constant of the input capacitors,
together with the filter time constant (1 µs internal plus the
additional capacitor at pin CF). For SDH/SONET
applications couple capacitors of 1.5 nF are
recommended, leading to a high-pass frequency of

Dissipation
Since the thermal resistance from junction to ambient
R
of the TSSOP package is higher than the thermal
th(j-a)
resistance of the SO package (see Chapter “Thermal
characteristics”), the dissipation should be considered
when using the TZA3044TT version.

For the TZA3044T (SO package), the worst case die
temperatureTj=85+115×0.3 = 119.5 °Cwhichis below
the maximum operating temperature.
For the TZA3044TT (TSSOP package), the worst casedie
temperature Tj=85+150×0.3 = 130 °C which is higher
than the maximum operating temperature, and therefore
strongly discouraged. It is recommended to lower the
thermalresistancefromjunctiontoambient, e.g. by means
of a dedicated board layout.
However, if the ambient temperature is limited to 75 °Cor
the power supply is limited to 3.3 ±0.3 V, the junction
temperature will stay below the maximum value without
further precautions.

HANDLING
This device is ESD sensitive and should be handled with care. Precautions should be taken to avoid damage through
electrostatic discharge. This is particularly important during assembly and handling of the bare die. Additional safety can
be obtained by bonding the V

SOLDERING
Introduction to soldering surface mount packages
Thistextgivesaverybriefinsight 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).
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not alwayssuitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
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.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
TZA3044; TZA3044B
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• 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;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswithleadsonfoursides,thefootprintmust
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.
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 dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Manual soldering
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemountdevices(SMDs)orprinted-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
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.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices, or systems where malfunction of these
products can reasonably be expected to result in personal injury. Philips customers using or selling these products for
use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such
improper use or sale.
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
ninety (90) days from the date of Philips' delivery. If there are data sheet limits not guaranteed, these will be separately
indicated in the data sheet. There is no post waffle pack testing performed on individual die. Although the most modern
processes are utilized for wafer sawing and die pick and place into waffle pack carriers, Philips Semiconductors has no
control of third party procedures in the handling, packing or assembly of the die. Accordingly, Philips Semiconductors
assumes no liability for device functionality or performance of the die or systems after handling, packing or assembly of
the die. It is the responsibility of the customer to test and qualify their application in which the die is used.
