ACS8530 SETS

Notes: (i) The frequency acceptance and generation range will be ±4.6 ppm around the required frequency when the external crystal

frequency accuracy is within a tolerance of ±4.6 ppm.

(ii) The fundamental acceptance range and generation range is ±9.2 ppm with an exact external crystal frequency of 12.800 MHz. This

is the default DPLL range, the range is also programmable from 0 to 80 ppm in 0.08 ppm steps.
