Vision IF amplifier and AGC detector

The vision IF amplifier contains three AC-coupled differential amplifier stages. Each differential stage includes a feedback network controlled by emitter degeneration.

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, while the peak white level is detected for positive video modulation. In order to reduce the reaction time for positive modulation, where a very large time constant is needed, an additional level detector is used to increase the discharge 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.

Tuner (TV/radio) and VIF AGC

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.

For FM radio operation, an AGC detector is provided to obtain some adjacent channel protection.

Frequency Phase-Locked Loop detector (FPLL)

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 proportional to the difference in frequency between the input signal and the VCO signal. 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. For positively modulated signals, the phase detector is gated by composite sync in order to avoid signal distortion with overmodulated VIF signals.

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.

The VCO centre frequency can be decreased (required for L accent standard) by activating an additional internal capacitor using logic ports LP0 and LP1. A variable resistor connected to LADJ can be used in conjunction with the second variable capacitor to set the VCO centre frequency to the required L accent value. 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.

Video demodulator and amplifier

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 video signal polarity can be switched in the demodulator stage in accordance with the relevant TV standard.

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 for B/G and L standard.

Preliminary specification

 

 

Multistandard multimedia IF-PLL and FM

TDA9816M

radio demodulator

The standard-dependent level shift in this stage delivers the same sync level for positive and negative modulation.

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.

SIF amplifier and AGC

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

The SIF AGC detector is related to the SIF input signal (average level of AM or FM carrier). It controls the SIF amplifier to provide a constant SIF signal to the

AM demodulator and single reference QSS mixer.

The 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’ mode according to the TV standard.

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 the intercarrier frequency by the regenerated picture carrier (VCO).

The mixer output signal is fed, via a high-pass filter used to attenuate the video signal components, to output pin 14. High performance hi-fi stereo sound processing can be achieved with this system.

For a simplified application without a sound IF SAW filter, the single reference QSS mixer can be switched to the intercarrier mode by connecting pin 27 and/or pin 28 to ground. In this mode, the sound IF signal passes through the vision IF SAW filter and the composite IF signal is then fed to the single reference QSS 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.

AM demodulator

A multiplier is used for AM demodulation. The modulated SIF amplifier output signal and the ‘in-phase’ limited

(AM is removed) SIF amplifier output signal are multiplied together. The demodulated output signal is fed, via an integrated low-pass filter used to attenuate the carrier harmonics, to the AF amplifier.

RIF amplifier and AGC

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 to the TV IF signal can be selected at the output (pin 14).

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 16) to control the tuner.

FM-PLL demodulator level detector and radio AFC

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.

Furthermore, the AF output signal can be force muted by connecting a resistor between pin 15 and ground. The soft mute function can be disabled by connecting a resistor between pin 15 and the power supply. See the application circuit in Fig.18.

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.

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 19. Furthermore, the steepness of the level detector output signal tracks that of the power supply voltage.

Multistandard multimedia IF-PLL and FM

TDA9816M

radio demodulator

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.

A ceramic resonator is used for phase shifting. This permits alignment-free operation.

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 13, 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.

The source selector operational amplifier selects and amplifies the appropriate AF source signal by means of the control logic: AM from the AM demodulator in TV L/L accent mode, FM from the FM demodulator via de-emphasis (internal resistor, external capacitor Cde-em at pin 12) in TV B/G mode or FM direct from the FM demodulator in radio mode.

Soft mute occurs when the internal level detector output voltage is lower than the mute threshold voltage at pin 11 (provided an external resistor is not connected between the limiter input, pin 15, and the supply voltage). The mute stage reduces the AF signal by 25 dB, with an internal time constant of approximately 7 ms.

If forced mute is active (see Table 2), or a resistor is connected between pin 15 and ground, the mute stage will reduce the AF signal level by more than 70 dB, with the same time constant.

Otherwise, the AF signal level 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 10.

Internal voltage stabilizer

The band gap 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.

Logic

The logic circuit detects the logic levels and threshold voltages at ports LP0, LP1 and LP2 and controls the internal functions as described in Table 2.
