TDA6650TT; TDA6651TT

5 V mixer/oscillator and low noise PLL synthesizer for hybrid

terrestrial tuner (digital and analog)

Rev. 05 — 10 January 2007

Product data sheet

1. General description

The TDA6650TT; TDA6651TT is a programmable 3-band mixer/oscillator and low phase

noise PLL synthesizer intended for pure 3-band tuner concepts applied to hybrid (digital

and analog) or digital only terrestrial and cable TV reception.

Different versions are available depending on the target application^[1]

[1] See Table 22 “Characteristics” for differences between TDA6651TT/C3/S2 and TDA6651TT/C3/S3.

The device includes three double balanced mixers for low, mid and high bands, three

oscillators for the corresponding bands, a switchable IF ampliﬁer, a wideband AGC

detector and a low noise PLL synthesizer. The frequencies of the three bands are shown

in Table 2. Two pins are available between the mixer output and the IF ampliﬁer input to

enable IF ﬁltering for improved signal handling and to improve the adjacent channel

rejection.

[1] RF input frequency is the frequency of the corresponding picture carrier for analog standard.

[2] RF input frequency is the frequency of the center of DVB-T channel.

The IF ampliﬁer is switchable in order to drive both symmetrical and asymmetrical

outputs. When it is used as an asymmetrical ampliﬁer, the IFOUTB pin needs to be

connected to the supply voltage V_CCA
