FUNCTIONAL DESCRIPTION
Figure 1 shows the simplified block diagram of the device.
The integrated circuit contains the following functional
blocks:
1. Gain controlled IF amplifier
2. Tuner AGC
3. Reference generation
4. Synthesizer for downconversion
5. Downconversion and complex filtering
6. Tracking low-pass filter with reference control
7. Low IF differential output stage
8. Logic control
9. Internal voltage stabilizer.
Gain controlled IF amplifier
The IF amplifier consists of three AC-coupled differential
stages. Gain control is performed by emitter degeneration.
Total gain control range is 70 dB (typ.). The differential
input impedance is typical 2 k
in parallel with 3 pF.
Tuner AGC
The tuner AGC is realized by a TakeOver Point (TOP)
network and a peak-level detector. The threshold level of
the peak detector can be adjusted by an external
potentiometer connected to pin TADJ. For IF signals
above this threshold the level detector provides a
discharge current to pin TAGC. An additional current
source is internally connected to this pin providing charge
current to the external tuner AGC capacitor. For IF signals
of 8 dB below the threshold voltage this current will be
increased by a factor of approximately 40 for faster AGC
reaction. The ratio of discharge to charge current is
normally approximately 2000 and approximately 50 for
fast mode.
For use of the device in different applications the charge
current can be switched off, for hybrid applications the
signal at pin TAGCEXT can be fed via a transmission gate
to pin TAGC (TDA9888TS; TDA9889TS combined with
analog IF), controlled by the 3-state input pin S2. With an
activated transmission gate all internal currents are off.
In the event that the tuner AGC is not needed (e.g. TAGC
from channel decoder or from an analog IF in hybrid
chassis), pin TADJ should be left open-circuit and
therefore all internal AGC currents will be switched off.

Reference generation
The 4 MHz crystal is the reference for the downconversion
synthesizer and the filter synthesizer.
The downconverted DVB frequency and the frequency
adjustment of the integrated filters are dependent on the
precision of the reference signal at pin REF. An operation
as crystal oscillator is possible as well as connecting this
input via a serial capacitor to another low-ohmic reference
frequency source.
The integrated divider-by-8 generates the internally
needed 500 kHz reference frequency for the DVB
synthesizer and the reference filter.
Synthesizer for downconversion
The PLL synthesizer for downconversion consists of a
Voltage Controlled Oscillator (VCO), a divider with a
standard dependent divider factor, a frequency phase
detector (constructed as a digital 3-state comparator) and
a charge pump.
The VCO operates as an integrated low radiation
relaxation oscillator at double the conversion frequency.
For downconversion the VCO frequency is divided-by-2 to
provide two differential square wave signals with exactly
90 degrees phase difference, independent of the VCO
frequency.
The frequency phase detector compares the down-divided
oscillator signal with the 500 kHz reference frequency
signal and controls, via the charge pump, the control
voltage at the external loop filter connected to pin LFS,
which is required to tune the VCO exactly to the wanted
frequency.
The divider, the frequency phase detector and the
reference frequency divider are constructed in a low
radiation technique to optimize the synthesizer spurious
suppression in the downconverted output signal.
Downconversion and complex filtering
The gain controlled IF signal from the IF amplifier is fed to
two identical linear mixers, operating in the `in phase' and
`quadrature' mode in accordance to the 0 and 90 degree
VCO signal from the synthesizer. With this, the
downconverted DVB low IF signal is available as an
I and Q signal in the frequency band from 1 to 9 MHz.
These signals are fed to the complex filter section. As a
result of adding both signals, the unwanted mirror signal
will be attenuated (approximately 34 dB). The unwanted
frequency components below 1 MHz are attenuated in a
high-pass filter. This signal is then fed through a
group-delay equalizer circuit.
Tracking low-pass filter with reference control
The low-pass filter is controlled by a reference signal
[generated by a frequency synthesizer and can be
switched by the standard selection (S0 and S1)].
The tracking low-pass filter is designed as a
Tschebyscheff filter to guarantee sufficient suppression for
the neighbouring picture carrier. An all-pass filter corrects
the characteristic to obtain a flat (equivalent ripple) group
delay behaviour.
Low IF differential output stage
The output amplifier consists of two identical differential
operational amplifiers with a high common mode (DC)
rejection ratio, to provide a constant DC voltage at the
output stage. The amplified Low IF (LIF) signal is available
as a differential signal with an amplitude of 2 V (p-p) and
DC level of 2 V (typ.) between the output terminals of both
amplifiers.
Logic control
The logic control provides an easy selection of the most
common standards for Europe, USA and Japan with the
two switches S0 and S1 (frequency selection different for
TDA9888TS and TDA9889TS) and controls all internal
standard dependent stages.
The five available tuner AGC modes can be set via the
3-state input pin S2 and R
TOP
connection (at pin TADJ).
Internal voltage stabilizer
The band gap circuit generates a voltage of approximately
2.4 V, independent of the supply voltage and the
temperature. A voltage regulator circuit, controlled by this
voltage, produces a constant voltage of 3.55 V which is
used as an internal reference voltage.

SOLDERING
Introduction to soldering surface mount packages
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).
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.
Reflow soldering
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.
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.
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:
below 225
C (SnPb process) or below 245
C (Pb-free
process)
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 mm
3
so called thick/large packages.
below 240
C (SnPb process) or below 260
C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm
3
so called small/thin packages.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount 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.
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.
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 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.
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 seconds to 5 seconds
between 270
C and 320
C.

Suitability of surface mount IC packages for wave and reflow soldering methods
Notes
1. For more detailed information on the BGA packages refer to the
"(LF)BGA Application Note" (AN01026); order a copy
from your Philips Semiconductors sales office.
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.
