U6224B General Description

The U6224B is a single chip frequency synthesizer with bi-directional I²C-bus control and an unidirectional 3-wire bus control, developed for TV-tuner applications. This IC contains an integrated preamplifier, a high frequency prescaler, a reference divider with programmable divider ratios, a crystal oscillator, a phase/ frequency detector together with a charge pump and a tuning amplifier. It perform also a EASY LINK interface to MOSMIC and Mixer IC.
