Overview
The LA7161V is an RF modulator which generates, from a baseband video and audio signal, PLL frequency synthesized RF TV channel signal in VHF band.

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.

Functions
• RF VCO
• RF mixer
• RF buffer
• Video clamp
• White clip
• Audio FM
• 4V regulator
• Reference OSC
