DSC2031
Low-Jitter Configurable Dual LVDS-CMOS Oscillator
General Description
The DSC2031 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 independent voltage level control.
The frequencies of the outputs can be
identical or independently derived from a
common PLL frequency source.
The
DSC2031 has provision for up to eight user-
defined pre-programmed, pin-selectable
output frequency combinations.
The
DSC2031 is also equipped with independent
pin-selectable output drive strengths for the
CMOS output to reduce EMI and noise.
DSC2031 is packaged in a 14-pin 3.2x2.5
mm QFN package and available in
temperature grades from Ext. Commercial to
Industrial.
