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.
