I2C-bus controlled multistandard alignment-free
IF-PLL demodulator with FM radio
TDA9887
1
FEATURES
• 5 V 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
• AM demodulator without extra reference circuit
• Alignment-free selective FM-PLL demodulator with high
linearity and low noise
• I2C-bus control for all functions
• I2C-bus transceiver with pin programmable Module
Address (MAD)
• Four selectable I2C-bus addresses
• Gated phase detector for L and L-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 of 33.4, 33.9,
38.0, 38.9, 45.75, and 58.75 MHz
• SIF and FM-AGC for radio (optional)
• 4 MHz reference frequency input: signal from
Phase-Locked Loop (PLL) tuning system or operating
as crystal oscillator
• Radio IF (RIF) input using the sound IF SAW input for
converting to 10.7 MHz, input frequencies are 41.3 MHz
for NTSC (M/N standard) applications and 33.3 MHz for
other applications
• 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
• Alignment-free FM radio demodulation at 10.7 MHz
• Radio AFC
• External FM input and demodulation.
• VIF-AGC monitor output at pin OP2
• External VIF-AGC setting via pin OP1

GENERAL DESCRIPTION
• Precise fully digital Automatic Frequency Control (AFC)
detector with 4-bit digital-to-analog converter, AFC bits
readable via I2C-bus
• TakeOver Point (TOP) adjustable via I2C-bus or
alternatively with potentiometer
The TDA9887 is an alignment-free multistandard
(PAL, SECAM and NTSC) vision and sound IF signal PLL
demodulator for positive and negative modulation,
including sound AM and FM processing. A special function
is implemented for the demodulation of FM radio signals
(fRIF = 10.7 MHz).
• 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
3
APPLICATIONS
• TV, VTR, PC, and STB applications.
• 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
