DESCRIPTION  
P8  
The SN761677 is a single-chip synthesized tuner IC  
designed for TV/VCR tuning systems. The circuit consists  
of a PLL synthesizer, 3-band local oscillators and mixer,  
30-V dc/dc converter for tuning the amplifier, four NPN  
emitter follower band drivers, four NPN open collector  
ports, and is available in a small package outline. The  
15-bit programmable counter and reference divider are  
controlled by I2C bus control. Tuning step frequency is  
selectable by the reference divider ratio for a 4-MHz Xtal  
oscillator.  
Pleasebe aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments
