DSC2140

DSC2240

Low-Jitter I

C/SPI Programmable HCSL Oscillator

General Description

The DSC2140 and DSC2240 series of

programmable,

high-performance

HCSL

oscillators utilizes a proven silicon MEMS

technology to provide excellent jitter and

stability while incorporating high output

frequency flexibility. DSC2140 and DSC2240

allow the user to modify the output

frequency using I

C or SPI interface,

respectively. User can also select from two

pre-programmed default output frequencies

using the control pin.

DSC2140 and DSC2240 are packaged in 14-

pin 3.2x2.5 mm QFN packages and available

in temperature grades from Ext. Commercial

to Industrial.
