2.5 Gbits/s postamplifier with level detectorTZA3014
FUNCTIONAL DESCRIPTION
The TZA3014 is a postamplifier with a RSSI circuit to
provide output signals for RSSI and LOS (see Fig.1). The
input signal can be amplified to a programmable level.
An active level control circuit ensures this level. The
control voltage on pin INV inverts the outputs, so avoiding
arequiredcomplicatedPrintedCircuit Board (PCB) layout.
An offset compensation circuit minimizes the effect of any
voltage offset present at the input.
The RSSI and LOS detector are based on a 7-stage
‘successive detection’ circuit which provides a logarithmic
output. The LOS detector is followed bya comparator with
aprogrammablethreshold.Theinputsignalleveldetection
is implemented to check if the input signal is above the
user-programmedlevel. The usercan ensure that datawill
only be transmitted when the input signal-to-noise ratio is
sufficient for low bit error rate system operation. A second
offset compensation circuit minimizes the effect of any
voltage offset present in the logarithmic amplifier.
RF input circuit
The input circuit contains internal 50 Ω resistors
decoupled to V
via an internal common mode 12 pF
CCA
capacitor (see Fig.4).
The inputs IN and INQ are DC-biased at approximately
V
− 0.33 V by an internal reference generator. The
CCA
TZA3014 can be DC-coupled, but AC coupling is
preferred. When DC-coupled, the drive source must
operate within the allowable input range
(V
− 1.0 V to V
CCA
+ 0.3 V). The DC-offset voltage
CCA
should stay below a few millivolts since the internal
DC-offset compensation circuit has a limited correction
range. When AC-coupled, do not use capacitors that
cause a 3 dB cut-off point at 50 kHz (postamplifier cut-off
point) or at 1 MHz (RSSI cut-off point).
RF output circuit
Matching the outputs of the postamplifier (seeFig.5) is not
mandatory. In most applications, the receiving end of the
transmission line will be properly matched, causing very
few reflections.
Matching the transmitting end of the transmission line to
absorb reflections only, is recommended for verysensitive
applications.

Fig.4 RF input circuit.
RF output level adjustment
The output level can be made compatible with CML or
PECL by adjusting the voltage on pin LEVEL. The
DC voltages on pins OUT and OUTQ relate to the
DC voltage on pin LEVEL. Due to the effect of the 50 Ω
load resistance at the receiving end, for a given
peak-to-peak value on pins OUT and OUTQ, a different
voltage is required on pin LEVEL in case the output is
AC-coupled and when the output is DC-coupled
(see Figs 5 and 6).
When pin LEVEL is not connected or connected to V
CCA
the postamplifier is in power-down state (see Fig.5).
DC-offset compensation loop
A DC-offset compensation loop connected between the
amplifier output and the buffer input maintains the toggle
point at the buffer input when there is no input signal
(see Fig.1). This active control circuit is integrated and
does not require an external capacitor. The loop
time constant determines the lower cut-off frequency of
the amplifier chain, and is internally fixed at approximately
5 kHz.
,
In such cases, 100 Ω pull-up resistors should be
connected to V
and pins OUT and OUTQ as close as
CCB
possible to the IC. However, for most applications these
matching resistors are not required.

RSSI and LOS detection
The TZA3014 monitors the level of the input AC signal.
Thisfunction can prevent the outputcircuitfrom reacting to
noise in casethere is no valid inputsignal, and can ensure
that only data is transmitted when there is sufficient input
signal for low bit error rate system operation.
The RSSI uses seven limiting amplifiers in a ‘successive
detection’ topology to closely approximate a logarithmic
response over a total range of 70 dB. The AC signal is
full-wave rectified by a detector at each amplifier stage.
Each detector output has a current driver followed by a
low-pass filter providing the first stage in the recovery of
the average value of the demodulated input signal. The
total current from each detector output is converted to a
voltage by an internal load resistor and then buffered.
When the RSSI output is used, input pin LOSTH is not to
be connected to GND (standby mode). The RSSI output
follows the internal 3 dB hysteresis of the LOS
comparator. The LOS comparator detects when the input
signal level rises above a programmable fixed threshold.
Then pin LOS gets a LOW-level. The threshold level is
determined by the voltage on pin LOSTH and by the level
of the input AC signal (see Fig.8). A filter with a nominal
timeconstant of 1 µs preventsnoise spikes from triggering
the level detector.
The LOS comparator has an internal 3 dB hysteresis and
drives an open-drain circuit with a 5 kΩ internal resistor
allowing it to directly interface positive or negative logic
circuits (see Fig.9).

Its response isindependent of the input signalpolarity due
to the circuit design and to the demodulating action of the

The sensitivity of the LOS detector is affected by the RMS

frequency.

Example: a 200 mV (p-p) single-ended 1.2 GB/s PRBS
input signal will have a V
voltage of VCC− 1.013 V.
RSSI
If the offset voltage of the first stage increases above a
certain level, the high DC gain of the amplifier circuit will
cause successive stages to limit prematurely. This is
prevented by the LOS detector offset control loop which
extends the lower end of the amplifier’s dynamic range.
The offset isautomatically and continuously compensated
by a feedback path from the last stage. An offset at the
output of the logarithmic converter is equivalent to a
change of amplitude at the input.
UsingDC-coupling, with signal absence, andVINnotequal

(mute), the LOS detector detects full signal. Only
INQ

result into a zero output.

Using a positive supply voltage
Although the TZA3014 has been designed to use a single
+3.3 V supply voltage (see Fig.11), some care should be
taken with respect to RF transmission lines. The on-chip
signals refer to the various VCCpins. The external
transmission lines will most likely be referred to the
pins GNDA and GNDB, being the system ground.
The RF signals will change from one reference plane to
another when interfacing the RF inputs and outputs.
A positive supply application is very vulnerable to
interference with respect to this point. For a successful
+3.3 V application, special care should be taken when
designing the PCB layout in order to reduce the influence
of interference and to keep the positive supply voltage as
clean as possible.

APPLICATION INFORMATION
RF input and output connections
Striplines, or microstrips, with an odd mode characteristic
impedanceof Zo=50Ωhaveto be used for thedifferential
RF connections on the PCB. This applies to both signal
inputs and signal outputs. Each pair of lines should have
the same length.
Grounding and power supply decoupling
The PCB ground connection has to be a large area of
copper connected to a common ground plane with an
inductance as low as possible.
Tominimize low frequency switching noiseinthe vicinity of
theTZA3014,the power supply line should be filteredonce
using a beaded capacitor circuit having a low cut-off
frequency.
The exposed die pad GNDp connection on the PCB must
be a large area of copper to aid the transfer of heat from
the IC to the PCB (see Figs 11 and 12).

SOLDERING
Introduction to soldering surface mount packages
Thistextgives a very brief insighttoacomplex 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 can still be used for
certainsurfacemount ICs, but it is not suitableforfinepitch
SMDs. In these situations reflow soldering is
recommended.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board byscreenprinting, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
convection or convection/infrared 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 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemount devices (SMDs) or printed-circuit boards
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:
• 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.
• Forpackageswith leads on four sides, the footprintmust
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 andbefore 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
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.

Suitability of surface mount IC packages for wave and reflow soldering methods
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
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. Wavesoldering isonly suitablefor 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.
