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.
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 (500Ω//40pF)
PLL
• 4 independent I2C addresses
• I2C 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.
