The DS1087L is a clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz. The DS1087L is shipped from the factory programmed at a specific frequency and spread-spectrum percentage. The user still has access to an internal frequency divider, selectable 2% or 4% dithered output, and programmable output power-down/disable mode through a 2-wire programming interface. All the device settings are stored in nonvolatile (NV) EEPROM allowing it to operate in stand-alone applications. The DS1087L has powerdown and output-enable control pins for power-sensitive applications.
