1.3 GHz PLL with I²C Bus for TV Tuner
U6207B
Description
The U6207B is a single chip frequency synthesizer with
I²C bus control. This IC contains a high frequency
prescaler which can be switched off. The maximum input
frequency at switched off prescaler is 220 MHz, so that
Features
D 1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
D 15 bit counter accepts input frequencies
up to 220 MHz
D mP-controlled by I²C bus
D 3 switching outputs (open collector)
special channels, e.g. weather forecast channels, can be
received. 3 open collector switching outputs are
available.
D 4 addresses selectable at Pin 7 for multituner
application
D 62.5 kHz (–1.3 GHz)/ 7.8125 kHz (–220 MHz)
