[LA7161V]
Features
* 5V operation. * PLL synthesized RF VCO (US : 3ch, 4ch, JPN : 1ch, 2ch , TWN : 13ch only), channel selection accomplished using two pins. * PLL synthesized (4.5MHz frequency) and tankless audio FM. * The 4 or 3.58MHz (color subcarrier) reference frequency for PLL can either be generated internally or input from an external source.
