FUNCTIONAL DESCRIPTION
Vision IF amplifier and AGC detector
The TDA9809M is comprised of the functional blocks
shown in Fig.1:
The vision IF amplifier contains three AC-coupled
differential amplifier stages. Each differential stage
includes a feedback network controlled by emitter
degeneration.
• Vision IF amplifier and AGC detector
• Tuner (TV/radio) and VIF AGC
The AGC detector generates the required VIF gain control
voltage for constant video output by charging/discharging
the AGC capacitor. The sync level of the video signal is
therefore detected for negative video modulation.
• Frequency Phase-Locked Loop (FPLL) detector
• VCO, Travelling Wave Divider (TWD) and TV AFC
• Video demodulator and amplifier
• Intercarrier mixer
• RIF amplifier and AGC detector
Tuner (TV/radio) and VIF AGC
• FM-PLL demodulator, level detector and radio AFC
For TV operation, the AGC capacitor voltage is converted
to an internal IF control signal and then fed to the tuner
AGC to generate the tuner AGC output current at
pin TAGC (open-collector output). The tuner AGC
takeover point can be adjusted at pin TADJ. This allows
the tuner to be matched to the SAW filter in order to
achieve the optimum IF input level.
• Audio Frequency (AF) signal processing
• Internal voltage stabilizer
• Logic.
For FM radio operation, an AGC detector is provided to
obtain some adjacent channel protection.

TDA9809M
Frequency Phased-Locked Loop detector (FPLL)
Intercarrier mixer
The VIF amplifier output signal is fed, via a limiting
amplifier, to a frequency and phase detector. During
acquisition, the frequency detector generates a DC current
that is proportional to the difference in frequency between
the input signal and the VCO signal.
The intercarrier mixer is realized by a multiplier.
The sound IF signal passes through the vision IF SAW
filter and the composite IF signal is then fed to the
intercarrier mixer. Here, the IF signal is multiplied by the
90° TWD output signal to convert the sound IF to the
intercarrier frequency. By using this quadrature detection,
the low frequency video signals are removed. The mixer
output signal is fed, via a high-pass filter used to attenuate
the video signal components, at output pin 10.
After frequency lock-in, the phase detector generates a
DC current proportional to the phase difference between
the input signal and the VCO signal. The DC current
generated by the frequency or phase detector is converted
to a DC voltage via the loop filter, which controls the VCO
frequency.
RIF amplifier and AGC detector
The radio IF amplifier amplifies the 10.7 MHz radio IF
signal. This signal is supplied by the tuner and is fed to the
RIF input (pin 4) via a matching circuit and a ceramic
band-pass filter. This amplifier contains two stages.
The first stage, a conventional 0 dB differential amplifier
designed for optimal dynamic range, is followed by a
switchable differential amplifier stage with a gain of 10 dB.
Either the radio IF or the TV IF signal can be selected at
the output (pin 10).
VCO, TWD and TV AFC
The VCO operates with a resonance circuit (with L and C
in parallel) at double the Picture Carrier (PC) frequency.
The VCO is controlled by two integrated variable
capacitors. The control voltage required to tune the VCO
from its free-running frequency to double the PC frequency
is generated by the FPLL and fed via the loop filter to the
first variable capacitor. This control voltage is amplified
and converted into a current which represents the AFC
output signal. At the centre frequency, the AFC output
current is zero.
The TWD divides the oscillator signal by 2 and generates
two differential output signals with a 90° phase difference
independent of frequency.
The RIF output signal is fed via ceramic band-pass filters
to the FM-PLL demodulator and the radio IF AGC detector.
The AGC threshold is very high and is designed to obtain
some adjacent channel protection. The AGC detector
output is fed to the tuner AGC output stage (pin 12) to
control the tuner.
Video demodulator and amplifier
FM-PLL demodulator, level detector and radio AFC
Video demodulation is realized by a multiplier designed for
low distortion and wide bandwidth. The vision IF input
signal and the ‘in-phase’ signal of the travelling wave
divider output are multiplied together.
The FM-PLL demodulator consists of a limiter and an FM
phase-locked loop. The 8-stage internally AC-coupled
limiter amplifies and limits the TV FM sound intercarrier or
the radio FM intermediate frequency signal prior to
demodulation. The limiter is designed for high sensitivity
and AM suppression with low DC offset and needs no
external pins for DC coupling.
The demodulated output signal is fed to the video amplifier
via an integrated low-pass filter used to attenuate the
carrier harmonics. This is an operational amplifier with
internal feedback and wide bandwidth. A low-pass filter is
integrated to attenuate the carrier harmonics. The video
output signal at Vo(vid) is 1.1 V (p-p) for nominal vision IF
modulation, in order to achieve 1 V (p-p) at the sound trap
output.
1998 Jan 08
Furthermore, the AF output signal can be force muted by
connecting a resistor between pin 11 and ground. The soft
mute function can be disabled by connecting a resistor
between pin 11 and the power supply. See the application
circuit in Fig.16.

Philips Semiconductors
Preliminary specification
Single standard multimedia IF-PLL and FM
radio demodulator
The FM-PLL consists of an integrated relaxation oscillator,
an integrated loop filter and a phase detector.
The oscillator is locked to the FM intercarrier signal output
from the limiter. As a result of locking, the oscillator
frequency tracks with the modulation of the input signal
and the oscillator control voltage is superimposed on the
AF voltage. The FM-PLL operates as an FM demodulator.
Soft mute occurs when the internal level detector output
voltage is lower than the mute threshold voltage at pin 8
(provided an external resistor is not connected between
the limiter input, pin 11, and the supply voltage). The mute
stage reduces the AF signal by 25 dB, with an internal time
constant of approximately 7 ms.
If a resistor is connected between pin 11 and ground
(forced mute), the mute stage will reduce the AF signal by
more than 70 dB with the same time constant.
The level detector detects, rectifies and amplifies the
output signals from the first 5 limiter stages. These signals
are then summed and the composite signal passed
through a low-pass filter, followed by a 6 dB output
amplifier. A DC voltage dependent on the limiter input level
is generated for controlling the behaviour of the AF soft
mute. The 6 dB output amplifier can be switched off via the
control logic and the level detector output signal fed to
pin 14. Furthermore, the steepness of the level detector
output signal tracks that of the power supply voltage.
Otherwise, the AF signal will not be reduced.
The AF post-amplifier, which was designed to include a
rail-to-rail output stage, provides the required AF output
level at pin 7.
Internal voltage stabilizer
The bandgap circuit generates a voltage of approximately
1.25 V internally, independent of supply voltage and
temperature. A voltage regulator circuit connected to this
voltage generates a constant 3.6 V which is used as an
internal reference voltage.
The radio Automatic Frequency Control (AFC) stage is
comprised of a 10.7 MHz phase shifting network, a phase
detector (quadrature demodulator), a differential amplifier
input stage (which receives the limiting amplifier output
signal) and a current mode output stage.
Logic
A ceramic resonator is used for phase shifting. This
permits alignment-free operation.
The logic circuit detects the logic levels and threshold
voltages at ports LP0 and LP2 and controls the internal
functions as described in Table 2.
AF signal processing
The AF signal processing stage consists of a pre-amplifier
for the FM-PLL demodulator output signal, an AF source
selector, a soft and forced mute stage with an integrated
time constant and an AF post-amplifier.
The FM demodulator output signal is pre-amplified by an
operational amplifier (30 dB gain) with internal feedback,
high gain and high common mode rejection. The feedback
circuit, together with external capacitor CDEC connected to
pin 9, keeps the DC level at the pre-amplifier output
constant (2.3 V). An external resistor connected in series
with CDEC provides a gain reduction capability.
The low-pass filter characteristic (130 kHz bandwidth) of
the amplifier reduces the harmonics of the IF signal at the
sound signal output.

Notes
1. Video and sound parameters are degraded at VP ≤ 4.5 V.
2. This parameter is not tested during production and is provided as application information for use in designing the
television receiver.
3. Loop bandwidth BL = 70 kHz (natural frequency fn = 12 kHz; damping factor d ≈ 3; calculated for peak level).
Resonance circuit of VCO: Q0 > 50; CVCO = 8.2 pF ± 0.25 pF; Cint ≈ 8.5 pF (loop voltage ≈ 2.7 V).
4. Temperature coefficient of external LC circuit is equal to zero.
5. Vi(VIF)(rms) = 10 mV; ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture
video modulation.
6. Vi(VIF) signal for nominal video signal.
7. The leakage current of the AGC capacitor should not exceed 1 µA to avoid larger tilt.
8. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 13). B = 5 MHz weighted
in accordance with “CCIR 567” .
9. The intermodulation figures are defined:
 V 0 at 3.58 (4.4) MHz 
α IM(0.92/1.1) = 20 log  -------------------------------------------------------  + 3.6 dB ; αIM(0.92/1.1) value at 0.92 or 1.1 MHz referenced to

 V 0 at 2.76 (3.3) MHz 
10. Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth = 70 kHz.
a) Modulation VSB; sound carrier off; fvideo > 0.5 MHz.
b) Sound carrier on; SIF SAW filter K9453; fvideo = 10 kHz to 10 MHz.
11. Response speed valid for a VIF input level range of 200 µV up to 70 mV.
12. A current source output is provided to match the AFC output signal to different tuning systems. The test circuit is
given in Fig.6 for TV mode and in Fig.11 for radio mode. The AFC steepness can be changed by the resistors at
pin 14.
a) A voltage output is provided to match the AFC output signal to different tuning systems. The DC load current
should not exceed 180 µA.

14. The intercarrier output signal at pin 10 can be calculated with the following formula using the video output signal at
pin 13 (Vo(video)(p-p) = 1.1 V typical) as a reference:
1
V o ( rms ) = 1.1 V ( p – p ) × ----------- × 10
2 2
V i ( SC )
----------------- ( dB ) + 6 dB ±3 dB
V i ( PC )
-------------------------------------------------------------------20
1
with ----------- = correction term for RMS value,
2 2
V i(SC)
-------------- (dB) = sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB,
V i(PC)
6 dB = correction term of internal circuitry and ±3 dB = tolerance of video output and intercarrier output amplitude
Vo(rms).
V i(SC)
Example: SAW filter G1962 (sound shelf: 20 dB) ⇒ ------------- = – 27 dB ⇒ V o(rms) = 32 mV (typ.) .
V i(PC)
15. Input level for second IF from an external generator with 50 Ω source impedance. AC-coupled with 10 nF capacitor,
fmod = 1 kHz, 27 kHz (54% FM deviation) of audio reference. A VIF/SIF input signal is not permitted. Pin 5 has to be
connected to the positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 µs (75 µs
at M standard) de-emphasis (modulator pre-emphasis has to be activated). The FM demodulator steepness
∆Vo(AF)/∆fAF is positive.
a) Second IF input level 10 mV (RMS).
16. Measured with an FM deviation of 27 kHz, the typical AF output signal is 500 mV (RMS) (Rx = 0 Ω). By using
Rx = 680 Ω the AF output signal is attenuated by 6 dB (250 mV RMS). For handling a frequency deviation of more
than 53 kHz the AF output signal has to be reduced by using Rx in order to avoid clipping (THD < 1.5%). For an
FM deviation up to 100 kHz an attenuation of 6 dB is recommended with Rx = 680 Ω.
17. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.
18. For all S/N measurements, the vision IF modulator used must meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees.
b) QSS AF performance, measured with the television-demodulator AMF2 (audio output, weighted S/N ratio) better
than 60 dB (deviation ±27 kHz) for 6 kHz sine wave black-to-white video modulation.
c) Picture-to-sound carrier ratio; PC/SC1 = 13 dB; (transmitter).
19. The PC/SC1 ratio at pins 1 and 2 is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1
ratio. This PC/SC1 ratio is necessary to achieve the S/NW values as noted. A different PC/SC1 ratio will change
these values.
20. Measurements taken with SAW filter G1962 (sound shelf: 20 dB) for vision and sound IF.
21. The RIF amplifier output (pin 10) must be connected to a multistandard application ceramic filter for
5.5, 6.0 and 10.7 MHz. This total load constitutes an impedance of 250 Ω.
22. d3 tested using two signals with frequencies of f1 = 10.5 MHz and f2 = 10.7 MHz, and with a level of Vi(4)(max)(rms) for
each signal. d3 is the ratio of the intermodulation product at 10.3 MHz to the output level of Vi(4)(max)(rms).
23. The control steepness of the radio AFC detector is dependent on the characteristic of the ceramic resonator, pin 18.
The figure given here will be obtained when applying a typical resonator of the type CDA 10.7 MC1-A (Murata).
The spread of the control steepness depends on the spread of the ceramic resonator characteristic (see Fig.11).

If wave soldering cannot be avoided, the following
conditions must be observed:
SOLDERING
Introduction
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
• The longitudinal axis of the package footprint must
be parallel to the solder flow and must incorporate
solder thieves at the downstream end.
Even with these conditions, only consider wave
soldering SSOP packages that have a body width of
4.4 mm, that is SSOP16 (SOT369-1) or
SSOP20 (SOT266-1).
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
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.
Reflow soldering
Reflow soldering techniques are suitable for all SSOP
packages.
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.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Repairing soldered joints
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) 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.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
Wave soldering
Wave soldering is not recommended for SSOP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
