U6209B
1.3 GHz PLL for TV- and VCR- Tuner
Description
The U6209B is a single chip PLL frequency synthesizer
with unidirectional I
2
C-bus control. This IC contains a
high frequency prescaler which can be switched off.
Five open collector switching outputs are available. The
U6209B has a programmable 512/1024 reference divider.
