TYPE NUMBER
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
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 I
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 I
TakeOver Point (TOP) adjustable via I
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
I
alignment-free IF-PLL demodulators

The TDA9885 is an alignment-free multistandard
(PAL and NTSC) vision and sound IF signal PLL
demodulator for negative modulation only and
FM processing.
The TDA9886 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.
