TDA9889TS
Philips Semiconductors
DVB selective AGC amplifier
Product specification
TDA9888TS; TDA9889TS
FEATURES
Applicable for terrestrial and cable TV reception
70 dB variable gain wide-band Intermediate Frequency
(IF) amplifier (AC-coupled)
Gain control via external control voltage (0 to 3 V)
2 V (p-p) differential low IF (downconverted) output for
direct Analog-to-Digital Converter (ADC) interfacing
Digital Video Broadcast (DVB) downconversion with
integrated selectivity (allows to use one SAW filter
applications)
Integrated anti-aliasing tracking low-pass filter
Fully integrated synthesizer controlled oscillator with
excellent phase noise performance
Synthesizer frequencies for a wide range of world wide
DVB standards (for IF centre frequencies of 36, 44
and 57 MHz) with different channel bandwidths
(6, 7 and 8 MHz) are possible; see Tables 1 and 2
4 MHz reference frequency input [signal from
Phase-Locked Loop (PLL) tuning system] or operating
as crystal oscillator
Tuner Automatic Gain Control (TAGC) detector for
independent tuner gain control loop applications
TAGC operating as peak-sync detector, fast reaction
time due to additional speed-up detector
TAGC switch for feed-through of TAGC signal from
analog TV demodulator (e.g. TDA9886) in case of
hybrid (analog and digital TV demodulation) application
Stabilizer circuit for ripple rejection and to achieve
constant output signals
Electrostatic discharge (ESD) protection for all pins.
GENERAL DESCRIPTION
The TDA9888TS; TDA9889TS is an AGC amplifier circuit
with integrated selectivity. The device provides
downconversion and filtering without alignment for all DVB
standards. The filtering considers the tough neighbouring
channel conditions.
