General description
The TDA6650ATT; TDA6651ATT 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.
[1]
See Table 20 “Characteristics” for differences between
TDA6651ATT/C3/S2 and TDA6651ATT/C3/S3.
The device includes three double balanced mixers for low, mid and high bands, three
oscillators for the corresponding bands, a switchable IF amplier, 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 amplier input to
enable IF ltering 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]
For bandwidth optimization please refer to
Application note AN01014.
The IF amplier is switchable in order to drive both symmetrical and asymmetrical
outputs. When it is used as an asymmetrical amplier, the IFOUTB pin needs to be
connected to the supply voltage VCCA.
