DSC2040
Low-Jitter Configurable HCSL Oscillator
General Description
The DSC2040 series of high performance
dual output oscillators utilize a proven silicon
MEMS technology to provide excellent jitter
and stability while incorporating additional
device functionality. The two outputs are
controlled by separate supply voltages to
allow for high output isolation. The
frequencies of the outputs can be identical or
independently derived from a common PLL
frequency source. The DSC2040 has
provision for up to eight user-defined pre-
programmed,
pin-selectable
output
frequency combinations.
DSC2040 is packaged in a 14-pin 3.2x2.5
mm QFN package and available in
temperature grades from Ext. Commercial to
Industrial.
