Philips Semiconductors Preliminary specification

Multistandard VIF-PLL
with QSS-IF and AM demodulator

FUNCTIONAL DESCRIPTION
Vision IF amplifier and input switch

The vision IF amplifier consists of three AC-coupled
differential amplifier stages. Each differential stage
comprises a feedback network controlled by emitter
degeneration. The first differential stage is extended by
two pairs of emitter followers to provide two IF input
channels. The VIF input can be selected by pin 30.

Tuner and VIF AGC

The AGC capacitor voltage is transferred to an internal IF
control signal, and is fed to the tuner AGC to generate the
tuner AGC output current (open-collector output).
The tuner AGC takeover point can be adjusted. This allows
the tuner and the SWIF filter to be matched to achieve the
optimum IF input level.

The AGC detector charges/discharges the AGC capacitor
to the required voltage for setting of VIF and tuner gain in
order to keep the video signal at a constant level.
Therefore for negative video modulation the sync level and
for positive video modulation the peak white level of the
video signal is detected. In order to reduce the reaction
time for positive modulation, where a very large time
constant is needed, an additional level detector increases
the discharging current of the AGC capacitor (fast mode)
in the event of a decreasing VIF amplitude step. The
additional level information is given by the black-level
detector voltage.

TDA9811

VCO, Travelling Wave Divider (TWD) and AFC

The VCO operates with a resonance circuit (with L and C
in parallel) at double the 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 actually double the PC
frequency is generated by the frequency-phase detector
and fed via the loop filter to the first variable capacitor
(FPLL). This control voltage is amplified and additionally
converted into a current which represents the AFC output
signal. The VCO centre frequency can be decreased
(required for L accent standard) by activating an additional
internal capacitor. This is achieved by using the L accent
switch. In this event the second variable capacitor can be
controlled by a variable resistor at the L accent switch for
setting the VCO centre frequency to the required L accent
value. At centre frequency the AFC output current is equal
to zero.

The oscillator signal is divided-by-two with a TWD which
generates two differential output signals with a 90 degree
phase difference independent of the frequency.

Video demodulator and amplifier

The video demodulator is realized by a multiplier which is
designed for low distortion and large bandwidth. The vision
IF input signal is multiplied with the ‘in phase’ signal of the
travelling wave divider output. In the demodulator stage
the video signal polarity can be switched in accordance
with the TV standard.

Frequency Phase Locked Loop detector (FPLL)

The VIF-amplifier output signal is fed into a frequency
detector and into a phase detector via a limiting amplifier.
During acquisition the frequency detector produces a DC
current proportional to the frequency difference between
the input and the VCO signal. After frequency lock-in the
phase detector produces a DC current proportional to the
phase difference between the VCO and the input signal.
The DC current of either frequency detector or phase
detector is converted into a DC voltage via the loop filter,
which controls the VCO frequency. In the event of positive
modulated signals the phase detector is gated by
composite sync in order to avoid signal distortion for
overmodulated VIF signals.

1995 Oct 03 6

The demodulator output signal is fed via an integrated
low-pass filter for attenuation of the carrier harmonics to
the video amplifier. The video amplifier is realized by an
operational amplifier with internal feedback and high
bandwidth. A low-pass filter is integrated to achieve an
attenuation of the carrier harmonics for B/G and
L standard. The standard dependent level shift in this
stage delivers the same sync level for positive and
negative modulation. The video output signal is 1 V (p-p)
for nominal vision IF modulation.

with QSS-IF and AM demodulator

Video buffer

For an easy adaption of the sound traps an operational
amplifier with internal feedback is used in the event of B/G
and L standard. This amplifier is featured with a high
bandwidth and 7 dB gain. The input impedance is adapted
for operating in combination with ceramic sound traps. The
output stage delivers a nominal 2 V (p-p) positive video
signal. Noise clipping is provided.

SIF amplifier and AGC

The sound IF amplifier consists of two AC-coupled
differential amplifier stages. Each differential stage
comprises a controlled feedback network provided by
emitter degeneration.

The SIF AGC detector is related to the SIF input signals
(average level of AM or FM carriers) and controls the SIF
amplifier to provide a constant SIF signal to the AM
demodulator and single reference QSS mixer. The SIF
AGC reaction time is set to ‘slow’ for nominal video
conditions. But with a decreasing VIF amplitude step the
SIF AGC is set to ‘fast’ mode controlled by the VIF AGC
detector. In FM mode this reaction time is also set to ‘fast’
controlled by the standard switch.

TDA9811

AM demodulator

The AM demodulator is realized by a multiplier. The
modulated SIF amplifier output signal is multiplied in
phase with the limited (AM is removed) SIF amplifier
output signal. The demodulator output signal is fed via an
integrated low-pass filter for attenuation of the carrier
harmonics to the AF amplifier.

1

Internal voltage stabilizer and

The bandgap circuit internally generates a voltage of
approximately 1.25 V, independent of supply voltage and
temperature. A voltage regulator circuit, connected to this
voltage, produces a constant voltage of 3.6 V which is
used as an internal reference voltage.

For all audio output signals the constant reference voltage
cannot be used because large output signals are required.
Therefore these signals refer to half the supply voltage to
achieve a symmetrical headroom, especially for the
rail-to-rail output stage. For ripple and noise attenuation

1

the

⁄2VP voltage has to be filtered via a low-pass filter by

using an external capacitor together with an integrated
resistor (fg= 5 Hz). For a fast setting to 1⁄2VP an internal
start-up circuit is added.

⁄2VP-reference

Single reference QSS mixer

The single reference QSS mixer is realized by a multiplier.
The SIF amplifier output signal is fed to the single
reference QSS mixer and converted to intercarrier
frequency by the regenerated picture carrier (VCO).
The mixer output signal is fed via a high-pass for
attenuation of the video signal components to the output
pin 20. With this system a high performance hi-fi stereo
sound processing can be achieved.

8. Offset current measured between pin 7 and half of supply voltage (VP= 2.5 V) under the following conditions: no
input signal at VIF input (pins 1, 2, 4 and 5) and VIF amplifier gain at minimum (V28=VP). Due to sample-and-hold
mode of the FPLL in L standard, the leakage current of the loop filter capacitor (C = 220 nF) should not exceed
500 nA.

10. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 2 V (p-p), in event of
CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 Ω resistor must be connected from
output to input (from pin 21 to pin 22).

11. The leakage current of the AGC capacitor should not exceed 1 µA at B/G standard respectively 10 nA current at
L standard. Larger currents will increase the tilt.

12. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 10). B = 5 MHz weighted

SOLDERING
Introduction

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.

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”

Soldering by dipping or by wave

The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

(order code 9398 652 90011).

TDA9811

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
