FUNCTIONAL DESCRIPTION
The TDA9809M is comprised of the functional blocks
shown in Fig.1:
Vision IF amplifier and AGC detector
Tuner (TV/radio) and VIF AGC
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
FM-PLL demodulator, level detector and radio AFC
Audio Frequency (AF) signal processing
Internal voltage stabilizer
Logic.
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.
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.
