DSC2111FI2-E0019
Crystal-less⢠Configurable Clock Generator
General Description
The DSC2111FI2-E0019 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 DSC2111FI2-E0019 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.
