CY2071AFXI

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
