FEATURES
? Suitable for negative vision modulation
? Applicable for IF frequencies of 38.9, 45.75 and
58.75 MHz
? Gain controlled wide-band Vision Intermediate
Frequency (VIF) amplifier (AC-coupled)
? True synchronous demodulation with active carrier
regeneration (ultra-linear demodulation, good
intermodulation figures, reduced harmonics and
excellent pulse response)
? Peak sync pulse AGC
? Video amplifier to match sound trap and sound filter
? AGC output voltage for tuner with fixed resistor for
takeover point setting
? AFC detector without extra reference circuit
? Alignment-free FM-PLL detector with high linearity
? Stabilizer circuit for ripple rejection and to achieve
constant output signals
? 5 to 9 V positive supply voltage range
? Low power consumption of 300 mW at 5 V supply
voltage.
GENERAL DESCRIPTION
