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 settop-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

? Qualified according to JEDEC for consumer applications

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

? 4 IF pins to connect a 2 pole bandpass

? Symmetrical IF preamplifier with low output impedance able to drive a compensated SAW filter (500?//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

? Bus controlled power down 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
