TDA9812 - Multistandard VIF-PLL and FM-PLL/AM demodulator
NXP Semiconductors
General Description
The TDA9812/T is an integrated circuit for multistandard vision IF signal processing and AM and FM sound demodulation in TV and VTR sets.
Key Features
5 V positive supply voltage.
Gain controlled wide band VIF-amplifier (AC-coupled).
True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response).
Gated phase detector for L/L accent standard.
VCO frequency switchable between L and L accent (alignment external) picture carrier frequency.
Separate video amplifier for sound trap buffering with.
