· 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 of 33.4, 33.9,38.0, 38.9, 45.75, and 58.75 MHz
· 4 MHz reference frequency input: signal from Phase-Locked Loop (PLL) tuning system or
operating as crystal oscillator
· 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 pin OP1
· Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog
converter, AFC bits readable via I2C-bus
· Take Over Point (TOP) adjustable via I2C-bus or alternatively with potentiometer
· Fully integrated sound carrier trap for 4.5, 5.5, 6.0, and 6.5 MHz, controlled by FM-PLL
oscillator
· Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode, PLL controlled
· SIF-AGC for gain controlled SIF amplifier, single reference QSS mixer able to operate in high
performance single reference QSS mode and in intercarrier mode, switchable via I2C-bus
· AM demodulator without extra reference circuit
· Alignment-free selective FM-PLL demodulator with high linearity and low noise
· Four selectable I2C-bus addresses
· I2C-bus control for all functions
· I2C-bus transceiver with pin programmable Module
Address (MAD).
