TDA9888TS; TDA9889TS
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.
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.
