3 1 Brief descriptin The tuner DCT 704x is designed fr digital cable set tp bx applicatin in cmpliance with the Eurpean digital cable standard ETS The tuner cnsists f a VHF/ UHF tuner, a SAW filter fr channel filtering, an IF amplifier with AGC and an antenna lp thrugh functin. The full frequency range frm 47 t 862 MHz is autmatically splitted int 3 bands and after gain setting and filtering cnverted t the standard IF frequency f 36 MHz by means f a mixer/scillatr IC. The tuner incrprates the Thmsn Universal Tuning System, which desn't require any band switching infrmatin. The unit is built n a lwlss printed circuit bard carrying all the cmpnents in a metal husing frame with tp and rear cvers. The aerial cnnectrs (IEC-male/female type) are munted n ne frame side; all ther cnnectins are made via pins at the bttm. The tuner cmplies with the requirements f radiatin, signal handling capability and immunity interference f CENELEC Eurpean standards EN55013 and EN Blck diagram SAW IF Amplifier Ant_in MOPLL TV_ut 1 1 RF_AGC +5V +33V I2C bus IF_ut IF_AGC PRELIMINARY SPECIFICATION Page: 3/20
