Features
•
•
•
Usable with a single 5-V power supply.
O n - chip IF AGC gives a stabl e PLL
demodulation characteristic.
Usable at both Japanese standard frequency
(IF = 403 MHz) and European standard
frequency (IF = 480 MHz).
AFC sensitivity can be adjusted by externally
set constants.
Digital AFC output is provided.
A keyed AFC pulse input pin permits MUSE
reception.
Video output leve l can be adjusted by an
external resistor. Maximum output: 1 V
