C Bus for TV Tuner
Description
The U6207B is a single chip frequency synthesizer with
I
2
C 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
1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
special channels, e.g. weather forecast channels, can be
received. 3 open collector switching outputs are
available.
15 bit counter accepts input frequencies
up to 220 MHz
P-controlled by I
