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.
Table 1.
[1]
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
enable IF filtering for improved signal handling and to improve the adjacent channel
rejection.
Table 2.
[1]
[2]
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
