FUNCTIONAL DESCRIPTION
that is approximately 4 MHz higher than the incoming
1st IF centre frequency.
Vision IF
In DTV 2nd IF mode the 2nd IF signal is obtained by
down-mixing the incoming DTV IF signal with the IF VCO
signal. The low-pass filtered DTV 2nd IF signal is available
as a differential signal at the DTV output. This signal may
have a maximum bandwidth of 10 MHz. The VCO
frequency is programmed via the I2C-bus in steps of
250 kHz.
The IF amplifier contains 3 AC-coupled control stages
which have a total gain control range of more than 66 dB.
The video signal is demodulated by means of an
alignment-free PLL carrier regenerator with an internal
VCO. This VCO is calibrated by means of a digital control
circuit which uses the external crystal frequency as a
reference. The frequency setting for the various standards
(33.4 MHz, 33.9 MHz, 38 MHz, 38.9 MHz, 45.75 MHz and
58.75 MHz) is realised via the I2C-bus. To improve
performance for phase modulated carrier signals the
control speed of the PLL can be increased by setting bit
FFI.
In DTV mode the AGC time constant is determined by a
capacitor on pin DTVIFAGC. There are two AGC modes:
internal and external. In the internal AGC mode the gain is
controlled by an internal AGC detector. The external AGC
mode is activated by bit AGCM. In this mode the
appropriate AGC pin is used as input, so that the IF gain
can be controlled by the DTV channel decoder.
The AFC output is generated by the digital control circuit of
the IF PLL demodulator and can be read via the I2C-bus.
For fast search tuning systems the window of the AFC can
be increased with a factor of three with bus bit AFW.
The IF PLL has two pins for connection of the PLL loop
filters, one for analog TV and one for DTV. This allows
each loop filter to be optimized for its application.
The AGC-detector operates on top sync or top white level.
The demodulation polarity is switched via the I2C-bus. The
AGC detector capacitor is integrated. The time-constant
can be chosen via I2C-bus bits AGC1 and AGC0. The
AGC has also an external mode which is activated by bit
AGCM. In this mode the IF gain is determined by an
external voltage on pin DTVIFAGC.
7.3
The PNX3000 has a separate sound IF input to enable
quasi-split sound applications. The sound IF amplifier is
similar to the vision IF amplifier and has a gain control
range of about 55 dB. The AGC detector measures the
average level of the AM or FM SIF carrier and ensures a
constant signal amplitude for the AM demodulator and
Quasi-Split Sound (QSS) mixer.
The IC has an integrated sound trap filter. The filter is
constructed as a cascade of three separate traps, to
realize sufficient suppression of the first and second sound
carriers. The trap frequencies are selected via the I2C-bus.
The single reference QSS mixer is realised by a multiplier.
In this multiplier the SIF signal is converted to the
intercarrier frequency by mixing it with the regenerated
picture carrier from the video IF VCO. With this system a
high performance stereo sound processing can be
achieved.
The IC has an integrated group delay correction filter. The
filter can be switched between the PAL BG curve and a flat
group delay response characteristic. This has the
advantage that in multi-standard receivers the video SAW
filter does not need to be switchable.
7.2
For applications without a SIF SAW filter the IC can also
be used in intercarrier mode. In this mode the composite
video signal from the VIF amplifier is fed to the QSS mixer
and converted to the intercarrier frequency.
DTV IF
Apart from processing analog TV signals, the IF circuit can
also be used to preprocess digital TV signals before they
are sent to a DTV channel decoder. For this application the
two modes of operation are DTV 1st IF and DTV 2nd IF.
For both operating modes the IF PLL must be set to
synthesizer mode.
AM sound demodulation is realised in the analog domain
by the QSS mixer. The modulated SIF signal is multiplied
in phase with the limited SIF signal. The demodulator
output signal is low-pass filtered for suppression of the
carrier harmonics. The demodulated AM signal can be
digitized by one of the audio ADCs.
In DTV 1st IF mode only the AGC function of the IF circuit
is used, so the DTV channel decoder must be able to
handle the 1st IF frequency. Because the AGC detector
operates on the down-mixed 2nd IF signal, it is still
important to program a valid frequency for the IF VCO. It is
recommended to set the frequency of the VCO to a value
2004 Oct 04
Sound IF
The QSS mixer can also be used for down-mixing an
FM radio IF signal to an intercarrier frequency, so that it
can be demodulated by the digital decoder. The IF PLL
must be set to synthesizer mode in this case. The
preferred solution is to supply the FM radio signal via a
11

separate SAW or ceramic filter to the DTV input of the
PNX3000. The reason is that the selectivity of a SAW filter
for TV sound is not sufficient for FM radio and, if the SIF
input is used, no tuner AGC information is available.
The IC has two RGB inputs. Both inputs can also be used
as YPbPr input for connecting video sources with an
YPbPr output like a DVD player. The RGB inputs can also
be used for fast insertion of RGB signals (for instance on
screen display menus) in the primary CVBS signal. The
fast insertion switch is located in the digital video
processor.
For high performance FM radio it is recommended that a
10.7 MHz FM radio IF signal is supplied to the external
2nd SIF input. In this case the IF signal must be filtered by
an external bandpass filter, that also functions as an
anti-alias filter. The low-pass filter before the 2nd SIF ADC
must be bypassed by setting bus bit SLPM.
The RGB signals are converted to YUV before further
processing. The YUV output signal is digitized by two
ADCs. The U and V components have half the bandwidth
of the Y signal, therefore the U and V signals are
multiplexed and digitized by one ADC.
The IC includes a separate AGC circuit for the 2nd SIF
signal. This AGC is needed for intercarrier sound
applications and when an external sound IF signal is
supplied to the 2nd SIF input. The AGC amplifier is
preceded by a second order high-pass filter for
suppression of video signal components. The AGC time
constant is determined by an external capacitor.
7.4
7.6
Video ADCs and anti-alias filters
The PNX3000 contains four video ADCs for analog and
digital video broadcast signals. The clock frequency for the
ADCs is either 27 MHz or 54 MHz. Two analog signals can
be multiplexed at the input of one ADC. Then the clock
frequency of the ADC is 54 MHz and the sample frequency
of each channel is 27 MHz.
CVBS/YC source selector
The video input selector consists of four independent
source selectors, that can select between the CVBS signal
coming from the IF part and four external CVBS signals.
Two of the external CVBS inputs can also be used as
YC input. One selector is used to select the signal for of
the primary video channel. A second selector selects the
CVBS or YC signal for the secondary channel. The third
and fourth selectors are used to select analog outputs
CVBS A and B, which can be used for SCART or line
output.
The video ADCs are 10-bit folding ADCs. The sample
frequency for standard 1fH video signals is 27 MHz. For
the YUV channel the sample frequency of the U and V
components is half the sample frequency of the Y signal.
For 2fH YPbPr or RGB input signals (for instance 480p or
1080i ATSC signals), the frequency that is used to sample
the YUV signals is twice as high as for 1fH signals. The
sample frequency is 54 MHz for Y and 27 MHz for
U and V. The high sample frequency requires two data
links to transport the video data to the digital video
processor.
The primary channel can be a CVBS or YC signal. If a
YC signal is selected for the secondary channel or for the
external CVBS outputs A or B, the luminance and
chrominance signals are added to obtain a CVBS signal.
The anti-alias filters before the ADCs limit the signal
bandwidth to prevent aliasing effects. The filters for YUV
can be bypassed by means of two separate bits: bit BPY
for the Y filter and bit BPUV for the U and V filters. This
enables the use of external anti-alias filters with increased
bandwidth for 2fH, RGB or YPbPr input signals.
The IC has an extra YC input for connection of a 3D comb
filter. The comb signal can only be selected for the primary
video channel. The input pin CVBS_DTV allows an analog
CVBS signal derived from a digital broadcast (MPEG)
signal to be recorded with an analog VCR. This signal
cannot be selected for the primary video channel.
Table 1 shows the signal bandwidths and sample rates for
the various types of video signals. Table 2 shows which
video signals are sent to the digital video processor for
both data link modes.
The video identification circuit detects the presence of a
video signal on the CVBS_IF input (pin CVBS0). The
identification output is normally used to detect transmitters
during search tuning and can be read via the I2C-bus. The
circuit can also be used to monitor the selected primary
CVBS or YC signal. Either mode is selected by bit VIM.

Audio source selectors and A to D converters
7.8
The PNX3000 contains two different audio source
selectors. The first selector selects which audio signals are
routed to the audio ADCs for further processing in the
digital domain. The two microphone inputs are also
connected to this selector. The selector has two outputs, a
primary channel and a secondary channel. The primary
audio channel is used for one stereo signal. The
secondary audio channel can carry a second stereo
signal, or two microphone signals, or one mono signal and
one microphone signal or one mono signal and one
AM sound signal.
The IC has two microphone inputs. One microphone input
can be used for voice control of the TV set with the help of
an intelligent voice command decoder. The second input
can be used for connection of a microphone for Karaoke.
To allow the use of microphones with different sensitivities
the gain of each microphone amplifier is switchable
between two values via the I2C-bus.
7.9
Clock generation, timing circuitry and black
level clamping
The IC contains two PLL circuits that derive the sample
clock for the ADCs and the bit and word clocks for the data
links from an external reference frequency. The reference
frequency must be a stable frequency of either 13.5 MHz
or 27 MHz from a crystal oscillator. The internal reference
frequency is always 13.5 MHz. If the external frequency is
27 MHz a prescaler must be activated by bus bit FXT.
The second selector selects which audio signals are fed to
the analog audio outputs for SCART and line out. This
selector also has two stereo inputs for demodulated sound
signals coming from the digital video processor.
The gain from an external audio input to an analog output
is 1. A supply voltage of 5 V allows input and output
amplitudes of 1 V (RMS) full scale. The PNX3000 has
separate supply voltage pins for the audio selector circuit.
To allow for input and output amplitudes of 2 V (RMS) full
scale, as required for compliance with the SCART
specification, an audio supply voltage of 8 V must be used.
One PLL is used to multiply the 13.5 MHz reference
frequency to the 27 MHz and 54 MHz clock frequencies
that are needed for the video ADCs. A second PLL is used
to obtain the 297 MHz bit clock for the data link
transmitters.
The audio ADCs are 1-bit sigma-delta converters that
operate at a clock frequency of 6.75 MHz. The audio
A to D clock is synchronous with the video A to D clock, so
that audio and video data can be sent over the same data
links. The effective audio sample rate is
f clk
---------- = 52.7 ksample/s.

2004 Oct 04
Microphone inputs
A special timing circuit is used to generate the horizontal
and vertical timing pulses that are needed in the IF part,
and also for clamping the black level of the selected video
signals to a defined value at the output of the video ADCs.
The horizontal and vertical timing information of the
primary and secondary video channels must be supplied
by the digital video processor on pins HV_PRIM and
HV_SEC. The signal on these pins must consist of a
13
Philips Semiconductors
Preliminary specification

processors
PNX3000
horizontal timing pulse that starts just before and ends just
after the horizontal sync pulse of the selected video signal.
To enable detection of the vertical blanking period, the
horizontal pulses must be wider during a number of lines
in the vertical blanking interval.
Table 2 shows which video signals are sent to the digital
video processor for both data link modes. In the standard
mode up to three video channels plus one sound IF signal
are digitized and transferred simultaneously over the data
links.
The clamp signal inside the IC is generated with the help
of the external horizontal timing pulse and the 13.5 MHz
clock. The vertical timing information is used to disable the
black level clamp, so that the black level is not disturbed
by the vertical sync pulse on the video signal. The clamp
pulse for the YUV channel can be derived from the primary
or the secondary HV pulse, and is selected by bus bit
CLPS.
The distance between both ICs that are connected via the
data link must not be larger than about 10 centimetres.
The two wires for each differential signal should be paired
in the layout of the printed-circuit board.
7.11
The slave address of the I2C-bus transceiver in the
PNX3000 has two possible values, selected via the
ADR pin. The maximum bus clock frequency is 400 kHz,
and the voltage swing of SCL and SDA can be 3.3 V
or 5 V. The I2C-bus transceiver also has a hardwired IRQ
output (open drain and LOW-active) for interruption of the
microprocessor when the value of an important status bit
in status byte 0 changes. The IRQ signal is maskable with
register 0FH.
To avoid signal disturbance, it is possible to disable the
black clamps when the horizontal PLL in the digital video
processor is not locked to the selected video signal. This
is done by bus bit CMP for the primary CVBS channel and
bus bit CMS for the secondary CVBS channel.
Special attention is required when the same CVBS input is
selected for primary and secondary CVBS channels.
In this case the black level clamp loop is only closed for the
primary CVBS input. Due to internal offsets this will
normally result in a deviation on the black level of the
digitized secondary CVBS output.
7.10
7.12
Power supply circuit
An internal bandgap circuit generates a stable voltage of
1.25 V. This voltage is multiplied to a reference voltage of
2.3 V, and a digital supply voltage of 2.5 V. These two
voltages must be decoupled by external capacitors.
A 1/2VP reference voltage for the audio ADCs also requires
an external decoupling capacitor. The PNX3000 contains
two voltage regulators to supply the SDACs that are used
in the digital video processor. Each regulator requires a
few external components (one transistor, two resistors and
a decoupling capacitor). The output voltage is adjustable
between 1.25 V and 3.3 V by selection of external
resistors values.
Data link transmitters
Three serial data links are used for transportation of the
digital video and audio data coming from the ADCs in the
PNX3000 to the digital video processor. The use of serial
data connections results in a considerable reduction in pin
count and the number of connection wires that are needed
between both ICs.
The communication between data link transmitter and data
link receiver consists of two signals, a data signal and a
strobe signal. The two signals together contain the data,
bit-sync and word-sync information. For optimal EMC
performance both data and strobe are low voltage
differential signals. The voltage swing on each wire is
300 mV.
7.13
East-west interface
The PNX3000 contains a voltage to current converter that
serves as the interface between the voltage output of the
digital video processor and the current input of the
east-west stage of the vertical deflection amplifier
(TDA8358). The transconductance is determined by the
value of an external resistor.
Each data word sent over a data link consists of 44 bits:
4 video samples of 10 bits each, 2 audio bits and
2 word-sync bits. The word clock is 13.5 MHz. The data
rate on each of the three data links is 594 Mbit/s.

K/W
Note
1. The value given for the thermal resistance from junction to ambient should only be considered as an indication. Most
of the dissipated heat is conveyed to the ambient air through the Printed-Circuit Board (PCB) on which the IC is
mounted. The actual value of the thermal resistance depends on the number of metal layers, size and layout of the
PCB, and also on the dissipation of other components on the PCB.
11 QUALITY SPECIFICATION
In accordance with document “SNW-FQ-611”.

Notes
1. The supply voltage for the analog audio part may have a value between 5 V and 8 V. For a supply voltage of 5 V the
maximum amplitude of in- and output signals is 1 V (RMS). For a supply voltage of 8 V the maximum amplitude of
in- and output signals is 2 V (RMS).
2. The value of the regulated voltage is determined by the external resistive voltage divider. The voltage range
mentioned relates to the voltage at the emitter of the external transistor. The stability of the voltage regulator loop

depends on the value of the decoupling capacitor Cdec on the emitter of the external transistor. Recommended value
Io
is C dec = 1.5 × ------ µF, with Io in mA.

3. This parameter is not tested during production and is just given as application information for the designer of the
television receiver.
4. Loop bandwidth BL = 60 kHz (natural fN = 15 kHz; damping factor d = 2; calculated with top sync level as IF PLL
input signal level).
5. The IF PLL demodulator uses an internal VCO (no external LC-circuit required) which is calibrated by means of a
digital control circuit which uses the clock frequency of the microcontroller/teletext decoder as a reference. The
required IF frequency for the various standards is set via the I2C-bus. When the system is locked the resulting
IF frequency is very accurate with a deviation from the nominal value of less than 25 kHz.
6. Measured at pin CVBSOUTIF with 10 mV (RMS) top sync input signal at VIF input.
7. So called projected zero point, i.e. with switched demodulator.
8. The signal amplitude at the CVBSOUTIF output depends on the setting of bits VA1 and VA0. The recommended
settings for negative modulation (bit PMOD = 0) is VA1 = VA0 = 1. For positive modulation (bit PMOD = 1) the
settings VA1 = 1 and VA0 = 0 is recommended. The Vo(dem)(p-p) and ∆Vo values specified are valid if the
recommended settings are used.
9. Measured in accordance with the test line given in Fig.3. For the differential phase test the peak white setting is
reduced to 87 %:
a) The differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and
smallest value relative to the subcarrier amplitude at blanking level.
b) The phase difference is defined as the difference in degrees between the largest and smallest phase angle.
10. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
batches which are made in the pilot production period.
11. This figure is valid for the complete video signal amplitude (peak white-to-black), see Fig.4.
12. The noise inverter is only active in the ‘strong signal mode’ (no noise detected in the incoming signal).
13. The test set-up and input conditions are given in Fig.5. Measurement is done with an input signal of 10 mV (RMS).
14. Measured at an input signal of 10 mV (RMS). The S/N is the ratio of black-to-white amplitude to the black level noise
voltage (RMS value); B = 5 MHz. Weighted in accordance with CCIR 567.
15. The time-constant of the IF AGC is internal and the speed of the AGC can be set via bus bits AGC1 and AGC0. The
AGC response time is also dependent on the acquisition time of the PLL demodulator. The values given are valid for
the ‘norm’ setting (AGC1 = 0 and AGC0 = 1) and when the PLL is in lock.
16. The AFC control voltage is generated by the digital tuning system of the PLL demodulator. This system uses the
external crystal frequency as a reference and is therefore very accurate. For this reason no maximum and minimum
values are given for the window sensitivity figures. The tuning information is supplied to the tuning system via the
I2C-bus. Two bits are reserved for this function. The AFC value is valid only when bit LOCK = 1.
17. Exceeding this amplitude leads to intermodulation distortion.
18. The intercarrier sound (2nd SIF) signal is not normally an analog output signal of the IC. It can be made available on
the DTV output pins by setting bus bits DSIF = 1 and DFIF = 0.
19. The weighted S/N ratio is measured under the following conditions:
a) The vision IF modulator incidental phase modulation for black-to-white jumps must be less than 0.5 degrees
b) QSS AF performance of the vision IF modulator, measured with the television demodulator AMF2 (audio output
and weighted S/N ratio) better than 60 dB (deviation 27 kHz) for 6 kHz sine wave black-to-white modulation
c) Picture-to-sound carrier ratio of the vision IF modulator: PC/SC1 = 13 dB (transmitter)

d) The measurements must be carried out with the Siemens SAW filters G3962 for vision IF and G9350 for sound IF.
Input level for sound IF 10 mV (RMS) with 27 kHz deviation
e) The PC/SC ratio at the vision IF input is calculated as the addition of the TV transmitter ratio and the SAW filter
PC/SC ratio. This PC/SC ratio is necessary to achieve the S/NW values as indicated.
20. The demodulated AM sound signal can be made available in the analog domain on LINE or SCART audio outputs
by selecting AM internal (bus bit AMX = 0).
21. The frequency range of the 2nd SIF channel is limited by the 2nd SIF anti-alias filter. If a 10.7 MHz FM radio IF signal
is supplied to the external 2nd SIF input; an external 10.7 MHz bandpass filter must be used; and the internal
anti-alias filter must be bypassed by setting bus bit SLPM = 1.
22. The cascade of sound trap and group delay correction filter compensates for the group delay pre-distortion of the BG
standard, curve A (see “Rec. ITU-R BT.470-4”). The indicated values are the difference between the group delay at
4.43 MHz and the group delay at 10 kHz.
23. The digitized U and V signals have the following polarity: U = +(B−Y) and V = +(R−Y).
24. The S/N ratio is defined as the ratio of the full scale black-to-white amplitude to the black level noise voltage
(RMS value).
25. The S/N ratio is defined as the ratio of the full scale peak-to-peak signal amplitude to the zero signal noise voltage
(RMS value).
26. The video ADC is specified as a stand-alone circuit. Distortion and noise of the video switch and anti-alias filters is
not included.
27. The gain of the microphone amplifiers can be switched between low (17 dB) and high (35 dB). The low gain can be
used for microphones with a sensitivity between 5 mV (RMS) and 40 mV (RMS) at 94 dB SPL. The high gain can be
used for microphones with a sensitivity of less than 5 mV (RMS) at 94 dB SPL.
28. If the audio supply voltage is 8 V; the 5 V full scale reference voltage for the audio A to D converters at pin 91
(VAADCP) is generated by the IC itself, using the internal bandgap reference. This gives the best power supply
rejection ratio for the digital audio outputs. If the audio supply voltage is 5 V; pin 91 must be connected to the external
5 V supply. This results in a reduced power supply rejection ratio for the digital audio outputs.
29. Signals HV_PRIM and HV_SEC must be generated by the digital video processor using a 13.5 MHz clock. Where
pulse widths are specified in clock pulses, a 13.5 MHz clock is assumed (1 clock pulse is 74.1 ns). To enable
detection of the vertical blanking interval, a larger pulse width is used for a number of lines during the vertical blanking
period; see Figs 9 and 10.
30. Most timing parameters in this section are expressed in number of clock cycles, abbreviated as ck.
31. The east-west drive circuit is a voltage to current converter circuit, that requires an external conversion resistor. The
open drain output transistor can only sink current. The relation between input voltage and output current is as follows:
Vi
I o = ------------------- where Rew is the external conversion resistor. The voltage across the external conversion resistor is
4 × R ew
equal to Vi/4. The voltage at output pin EWIOUT must not be lower than Vi/4 + 0.25 V. The output current must not
be larger than 1.2 mA.
32. The switching levels of pins SDA and SCL are compatible with an external signal amplitude of 3.3 V and 5 V.
33. The IRQ output is an open-drain output; active LOW. The pin IRQ must be loaded with a pull-up resistor.

13 TEST AND APPLICATION INFORMATION
13.1
Power supply decoupling
For optimal THD and SNR performance of the analog and digital audio channels, it is important to have stable 5 V and
8 V supply voltages for the audio part of the PNX3000.
The following pins need a stable supply voltage without disturbances in the baseband audio frequency range:
• Pins VCC(1ASW) and VCC(2ASW) (pins 98 and 88); the supply voltage for the analog audio switches. The supply current
to both of these pins is less than 5 mA. Note that this supply voltage may be 5 V or 8 V.
• Pin VAADCP (pin 91); the 5 V full scale reference for the audio ADCs. The current consumption of this pin is about
0.25 mA. This pin must only be connected to the 5 V supply if an audio supply voltage (pins VCC(1ASW) and VCC(2ASW))
of 5 V is used. If an audio supply of 8 V is used, this pin must not be connected to the 5 V supply voltage. In this case
the reference voltage is generated by the IC itself, and only a decoupling capacitor should be connected to this pin.
• Pin VCC(AADC) (pin 77) is the 5 V supply voltage for the audio ADCs. The supply current for this pin is about 23 mA.

15 SOLDERING
15.1
Introduction to soldering surface mount
packages
To overcome these problems the double-wave soldering
method was specifically developed.
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).
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.
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
15.2
• 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;
Reflow soldering
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
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.
Driven by legislation and environmental forces the
worldwide use of lead-free solder pastes is increasing.
The footprint must incorporate solder thieves at the
downstream end.
• 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,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 seconds 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 °C to 270 °C depending on solder paste material. The
top-surface temperature of the packages should
preferably be kept:
Typical dwell time of the leads in the wave ranges from
3 seconds to 4 seconds at 250 °C or 265 °C, depending
on solder material applied, SnPb or Pb-free respectively.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
– for all BGA, HTSSON..T and SSOP..T packages
– for packages with a thickness ≥ 2.5 mm
– for packages with a thickness < 2.5 mm and a
volume ≥ 350 mm3 so called thick/large packages.
15.4
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.
• below 240 °C (SnPb process) or below 260 °C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm3 so called small/thin packages.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
15.3
When using a dedicated tool, all other leads can be
soldered in one operation within 2 seconds to 5 seconds
between 270 °C and 320 °C.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards

2. 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”.
3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
5. 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.
6. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP 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.
8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
9. Hot bar soldering or manual soldering is suitable for PMFP packages.
