Functional Description

The CY2907 is a general purpose clock generator designed for use in a wide variety of applications — from graphics to PC peripherals to disk drives. It generates selectable system clock frequencies from a single reference input (crystal or reference clock). The CY2907 is configured with an EPROM array, similar to the other devices in the Cypress EPROM Programmable Clock family, making it easy to customize for any application. Furthermore, the CY2907 is compatible with all industry standard 9107 and 9108 clock synthesizers.
