6 / 61 page TUA6034, TUA6036 Specification 6 V 2.5, 2004-04-28 Product Info General Description The TUA6034, TUA6036 ’TAIFUN’ device combines a mixer-oscillator block with a digitally programmable phase locked loop (PLL) for use in TV and VCR tuners and in set- top-box applications. Ordering Information Type Ordering Code Package TUA6034-T Q67034-H0009 TSSOP-38 TUA6036-T Q67037-A0012 TSSOP-38 TUA6034-V Q67034-H0008 VQFN-48 Features General • Suitable for PAL, NTSC, DVB and ATSC • Wideband AGC detector for internal tuner AGC − 5 programmable take-over points − 2 programmable time constants • Low phase noise • Full ESD protection Mixer/Oscillator • High impedance mixer input (common emitter) for LOW band • Low impedance mixer input (common base) for MID band • Low impedance mixer input (common base) for HIGH band • 2 pin oscillator for LOW band • 2 pin oscillator for MID band • 4 pin oscillator for HIGH band IF-Amplifier • Symmetrical IF preamplifier with low output impedance able to drive a compensated SAW filter (500 Ω//40pF) PLL • 4 independent I 2C addresses •I 2C bus protocol compatible with 3.3 V and 5V micro-controllers up to 400 kHz • High voltage VCO tuning output • 4 PNP ports • 1 NPN port/ADC input • Internal LOW/MID/HIGH band switch • Stand-by mode • Lock-in flag • 6 programmable reference divider ratios (24, 28, 32, 64, 80, 128) • 4 programmable charge pump currents Application • The IC is suitable for PAL, NTSC, DVB-C, DVB-T, ISDB-T and ATSC tuners. The focus is on digital terrestrial. The AGC stage makes the tuner AGC independent of the Video-IF AGC. |
