DSC2111FL2-E0018 Datasheet, PDF (1/6 Pages) Micrel Semiconductor – Crystal-less™ Configurable Clock Generator

DSC2111FL2-E0018
Crystal-less™ Configurable Clock Generator
General Description
The DSC2111FL2-E0018 is a programmable, high
performance dual LVCMOS output oscillator utilizing
Micrel's proven silicon MEMS technology to provide
excellent jitter and stability while incorporating
high output frequency flexibility and drive strength
control.
The DSC2111FL2-E0018 allows the user to
independently modify the frequency of each output
and LVCMOS drive strength using I2C interface.
The user can also select from two pre-programmed
default output frequencies using the frequency
select pin.
