Description
The U6220B is a single chip frequency synthesizer with I2C 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’).
