DSC2033
Low-Jitter Configurable Dual LVDS Oscillator
General Description
The DSC2033 series of high performance
dual output LVDS 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
DSC2033 has provision for up to eight user-
defined pre-programmed, pin-selectable
output frequency combinations.
DSC2033 is packaged in a 14-pin 3.2x2.5
mm QFN package and available in
temperature grades from Ext. Commercial to
Industrial.
