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.
Features
1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
Five open collector switching outputs are available. The
U6209B has a programmable 512/1024 reference divider.
15 bit counter accepts input frequencies up to
170 MHz
Programmable reference divider: divider by 512 or
1024
P-controlled by I
2
C-Bus (MC44818 data format
compatible)
Five port outputs (open collector )
Four addresses selectable at Pin 10 for multi-tuner
application
31.25 kHz ( –1.3 GHz ) / 3.90625 kHz ( –170 MHz )
tuning steps with 4MHz Xtal
Electrostatic protection according to MILSTD 883
