Ja nevim jestli to souvisi, ale kazdopadne tahle hodnota (3,579545MHz)
byva u dost ruznych obvodu mimo televizni techniku. Viz napr. zmineny
MT8870, je to primo v datasheetu
(http://assets.zarlink.com/DS/zarlink_MT8870D_OCT_06.pdf): "A 3.579545
MHz crystal connected between pins OSC1 and OSC2
completes the internal oscillator circuit."
