TD7627FN
3-WIRE AND I2 C BUS SYSTEM, 2.7 GHz DIRECT TWO MODULUS-TYPE FREQUENCY SYNTHESIZER FOR CATV
The TD7627FN can be combined with a micro CPU to create a
highly functional frequency synthesizer. The control data
conforms to 3-wire bus and standard I2 C bus formats. BUS-SW
can be used to easily switch for easy tuner system set-up.
