Built-in PLL circuit
•A/D converter (6 bits, 1 channel)
•Includes an IF counter and I/O ports for
simplified interfacing
•Adopts an AM double conversion reception
technique
Further improved to noise reduction
•Superlative three-signal characteristics
•Improved medium and weak field NC
characteristics
•Improved separation characteristics
•Built-in anti-birdie filter
•Multipath sensor outputs
(analog and digital outputs)
Support for lower total system costs
•AM double-conversion (up-conversion system)
•Improved FM IF circuit (automatic wide/narrow
CF switching with software in the presence
of adjacent channel interference)
•Reduction in sample-to-sample IF gain
variations by 1/3 simplifies adjustments during
manufacturing
Supports end-product miniaturization
•High-frequency signal lines can be handled
inside the tuner pack
•Easily meets the new FCC regulations
Package: QFP80 (14
