... Philips Semiconductors Multistandard VIF-PLL and FM-PLL/AM demodulator FUNCTIONAL DESCRIPTION Vision IF amplifier The vision IF amplifier consists of three AC-coupled differential amplifier stages. Each differential stage comprises a feedback network controlled by emitter degeneration. 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) ...
