Features

? Flash-programmable capacitor tuning array for low

ppm initial frequency clock output

? Low clock output jitter

— 4 ps typ. RMS period jitter

— ±30 ps typ. peak-to-peak period jitter

? Flash-programmable dividers

? Two-pin programming interface

? On-chip oscillator runs from 10–48-MHz crystal

? Five selectable post-divide options, using reference

oscillator output

? Programmable asynchronous or synchronous OE and

PWR_DWN modes

? 2.7V to 3.6V operation

? Controlled rise and fall times and output slew rate

Benefits

? Enables fine-tuning of output clock frequency by

adjusting CLoad of the crystal

? Allows multiple programming opportunities to correct

errors, and control excess inventory

? Enables programming of output frequency after

packaging

? PPM clock output error can be adjusted in package

? Provides flexibility in output configurations and testing

? Enables low-power operation or output enable function

? Provides flexibility for system applications through

selectable instantaneous or synchronous change in

outputs

? Enables encapsulation in small-size, surface-mount

packages
