TV AUTOMATIC FINE-TUNING CIRCUIT
• HIGH SENSITIVITY
• 25kHz MAX. FREQUENCY DEVIATION
• INTERNAL VOLTAGE REGULATOR
• INTERNAL AGC
GENERAL DESCRIPTION-The ITT3064 is a TV
automatic fine-tuning linear integrated circuit
constructed on a single chip. It combines all
of the automatic fine-tuning circuitry, except
transformers, in one integrated circuit. Systems
with low level I.F. amplifiers can now achieve
tuning accuracies of ±25 kHz due to the
ITT3064's high sensitivity. Internal voltage regulation
improves overall performance and reduces
system cost.
