C/SPI Programmable Dual CMOS Oscillator
General Description
The DSC2111 and DSC2211 series of
programmable, high-performance dual CMOS
oscillators utilizes a proven silicon MEMS
technology to provide excellent jitter and
stability while incorporating high output
frequency flexibility and drive strength
control. DSC2111 and DSC2211 allow the
user to independently modify the frequency
of each output and CMOS drive strength
using I
2
C or SPI interface, respectively. User
can also select from two pre-programmed
default output frequencies using the control
pin.
DSC2111 and DSC2211 are packaged in 14-
pin 3.2x2.5 mm QFN packages and available
in temperature grades from Ext. Commercial
to Automotive.
