Description



Features:

5V supply voltage
Gain controlled wide-band Vision Intermediate
Frequency (VIF) amplifier, AC-coupled
Multistandard true synchronous demodulation with
active carrier regeneration: very linear demodulation,
good intermodulation figures, reduced harmonics, and
excellent pulse response
Gated phase detector for LandL-accent standard
Fully integrated VIF Voltage Controlled Oscillator
VCO), alignment-free, frequencies switchable for all
negative and positive modulated standards via I2C-bus
Digital acquisition help, VIF frequencies of33.4,33.9,
38.0,38.9,45.75,and58.75MHz
4MHz reference frequency input: signal from
Phase-Locked Loop (PLL) tuning system or operating
VIF Automatic Gain Control (AGC) detector for gain
control, operating as peak sync detector for negative
modulated signals and as a peak white detector for
positive modulated signals
External AGC setting via pinOP1
PrecisefullydigitalAutomaticFrequencyControl(AFC
detector with 4-bit digital-to-analog converter, AFC bit readable via I2C-bus
TakeOver Point (TOP) adjustable via I 2C-bus or
alternatively with potentiometer
Fully integrated sound carrier trap for4.5,5.5,
6.0,and6.5MHz, controlled by FM-PLL oscillator
SoundIF (SIF) input for single reference Quasi Split
