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.
