2 / 22 page 2004 Nov 02 2 Philips Semiconductors Product specification DVB selective AGC amplifier 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. ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA9888TS SSOP16 plastic shrink small outline package; 16 leads; body width 5.3 mm SOT338-1 TDA9889TS |
