DSC2133 Datasheet, PDF (1/6 Pages) Micrel Semiconductor – Low-Jitter I2C/SPI Programmable Dual LVDS Oscillator

DSC2133 DSC2233
Low-Jitter I²C/SPI Programmable Dual LVDS Oscillator
Datasheet
General Description
The DSC2133 and DSC2233 series of
programmable, high-performance dual LVDS
oscillators utilizes a proven silicon MEMS
technology to provide excellent jitter and
stability while incorporating high output
frequency flexibility. DSC2133 and DSC2233
allow the user to independently modify the
frequency of each output using I²C or SPI
interface, respectively. User can also select
from two pre-programmed default output
frequencies using the control pin.
DSC2133 and DSC2233 are packaged in 14-
pin 3.2x2.5 mm QFN package and available
in temperature grades from Ext. Commercial
to Industrial.
