Functional Description

The CY2071A is a general-purpose clock synthesizer designed for use in applications such as modems, disk drives, CD-ROM drives, video CD players, games, set-top boxes, and data/telecommunications. The device offers up to three configurable clock outputs in an 8-pin, 150-mil SOIC package and can operate off either a 3.3V or 5V power supply. The on-chip reference oscillator is designed for 10 MHz to 25 MHz crystals. Alternatively, an external reference clock of frequency between 1 MHz and 30 MHz can be used.
