General Description
The DS1087L is a clock generator that produces a
spread-spectrum (dithered) square-wave output of fre-
quencies from 130kHz to 66.6MHz. The DS1087L is
shipped from the factory programmed at a specific fre-
quency 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 program-
ming interface. All the device settings are stored in non-
volatile (NV) EEPROM allowing it to operate in
stand-alone applications. The DS1087L has power-
down and output-enable control pins for power-sensi-
tive applications.
