1.3 GHz PLL for TV- and VCR- Tuner
Description
The U6220B is a single chip frequency synthesizer with
I
2
C bus and 3-wire bus control (universal bus). This IC
contains a high frequency prescaler, a crystal oscillator,
a switchable reference divider, 5 open collector switching
outputs and an additional mixer switch output for band
switching. The U6220B is especially designed for low
cost, high performance 2-band and EasyLink tuners
(please see application note ANT017 ‘Semiconductors
for TV Tuners - The New EasyLink Concept’).
Features
1.3 GHz divide-by-8 prescaler integrated
EasyLink interface to MOSMIC and mixer IC
Universal bus:
