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. Features • Single phase-locked loop architecture • EPROM programmability • Factory-programmable (CY2071A, CY2071AI) or field-programmable (CY2071AF, CY2071AFI) device options • Up to three configurable outputs • Low skew, low jitter, high-accuracy outputs • Internal loop filter • Power management (OE) • Frequency select options • Configurable 5V or 3.3V operation • 8-pin 150-mil SOIC package Benefits • Generates a custom frequency from an external source • Easy customization and fast turnaround • Programming support available for all opportunities • Generates three related frequencies from a single device • Meets critical industry standard timing requirements • Alleviates the need for external components • Supports low-power applications • Three outputs with two user-selectable frequencies • Supports industry standard design platforms • Industry standard packaging saves on board space
