TD7624AFN
3-WIRE AND I²C BUS SYSTEM, 1.3 GHz DIRECT TWO MODULUS-TYPE FREQUENCY
SYNTHESIZER FOR TV AND CATV
The TD7624AFN can be combined with a micro CPU to create a
highly functional frequency synthesizer. The control data
conforms to 3-wire bus and standard I²C bus formats. BUS-SW
can be used to easily switch for easy tuner system set-up.
