DESCRIPTION  
The SN761681 is a synthesized tuner IC designed for  
TV tuning systems. The circuit consists of a PLL  
synthesizer, three-band local oscillator and mixer,  
30-V output tuning amplifier, four NPN band-switch  
drivers, and is available in a small-outline package. A  
15-bit programmable counter and reference divider  
are controlled by I2C bus protocol. Tuning step  
frequency is selectable by this reference divider ratio  
for a crystal oscillator.
