1. General description
2. Features
TDA6500TT and TDA6501TT are programmable 2-mixer, 3-oscillator and synthesizer
MOPLLs intended for pure 3-band tuner concepts.
The device includes two double balanced mixers for the low and mid/high bands and three
oscillators for the low, mid and high bands, respectively. Other functions are an
IF amplifier, a wide-band AGC detector and a PLL synthesizer. Two pins are available
between the mixer output and the IF amplifier input to enable IF filtering for improved
signal handling.
The device can be controlled according to the I
