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
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
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
TakeOver 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).
2 GENERAL DESCRIPTION
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.
3 APPLICATIONS
TV, VTR, PC, and STB applications.

6. The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the
internal video signal with 1.1 V (p-p) as a reference:
Vo(intc)(rms) =
1.1 × -----1----- × 10r
22
V
and
r
=

×
V-V----ii-((-SP---CC---))
( dB )
+

dB
±

dB
where:
-----1-----
22
is the correction term for RMS value,
VV-----ii-((--SP---CC----)) (dB)
is the sound-to-picture carrier ratio at pins VIF1 and VIF2
in dB, 6 dB is the correction term of internal circuitry and ±3 dB is the tolerance of video output and intercarrier output
Vo(intc)(rms).
7. Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from
the tuning system.
