1.3 GHz PLL for TV- and VCR- Tuner
U6206B
Description
The U6206B is a single chip PLL frequency synthesizer
with unidirectional I²C bus control. This IC contains a
high frequency prescaler which can be switched off.
5 open collector switching outputs are available.
Features
D 1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
D 15 bit counter accepts input frequencies up to
170 MHz
D mP-controlled by I²C-Bus
D 5 switching outputs (open collector )
D 4 addresses selectable at Pin 8 for multituner
application
D 62.5 kHz (–1.3 GHz)/ 7.8125 kHz (–170 MHz) tuning
steps
D Electrostatic protection according to MILSTD 883
D SO16 small package
Package: SO16
