U664B datasheet pinout


Frequency divider + 64 for frequency sythesizes in TV-tuner.

The TELEFUNKEN IC used is available in different versions:

• The U664B version is stable even without an input signal and does not oscillate.

• The U664BS version oscillates due to internal feedback when there is no input signal


1. High input sensitivity
2. Large operation frequency range
3. High dynamic stability
4. Low power dissipation
